β›ˆοΈ The Les Cheneaux Islands sit along the northern shore of Lake Huron, thirty-six low, forested islands broken apart by narrow channels, hidden bays, and sheltered passages. Their French name means β€œthe channels,” and once you see the place from the water, the name makes perfect sense. 🌊

This is one of the most distinctive boating landscapes in the Great Lakes. The islands stretch along roughly twelve miles of shoreline on the southeastern edge of Michigan’s Upper Peninsula, creating a maze of protected water that feels intimate even though it opens directly onto Lake Huron. A small boat can move through calm coves and quiet passages one minute, then look east and see weather building over one of the largest freshwater lakes on Earth.

That contrast is what makes the place so dramatic.

The Les Cheneaux are not high, cliffed islands. They are low, wooded, limestone-and-dolostone islands shaped by Great Lakes geology, glacial history, clear water, and exposed bedrock. The surrounding region belongs to the same broad Niagara Escarpment story that runs through the Great Lakes, where resistant carbonate rock creates some of the most recognizable shorelines in the basin.

But the culture here is just as important as the geology.

Les Cheneaux became a summer cottage and boating destination in the late nineteenth and early twentieth centuries, and it never fully lost that older Great Lakes rhythm. Hessel, Cedarville, the channels, the docks, and the island cottages still carry the feeling of a place built around boats rather than speed or spectacle.

That is why the wooden boats matter.

The classic mahogany runabouts and antique wooden boats are not just decoration here. They are part of a living boating culture that survived because the channels protected them, the cold water preserved them, and families kept using them generation after generation. Hessel’s wooden boat tradition became so strong that the area now hosts one of the best-known antique wooden boat shows in the country.

And then the weather arrives.

A summer thunderstorm crossing Lake Huron into the Les Cheneaux channels turns the whole place cinematic: dark water, white docks, low islands, polished wooden boats tied tight, and thunder rolling over passages that people have navigated by canoe, sail, and motor for centuries.

Some Great Lakes places became famous by getting bigger.

Les Cheneaux stayed unforgettable by staying itself.

What place do you think has resisted modern tourism better than almost anywhere else?

🍷 The Finger Lakes wine region exists because of ice, depth, and water that refuses to behave like ordinary water.

Seneca Lake is 618 feet deep. Cayuga Lake reaches 435 feet. Those depths are not just trivia. They are the reason this part of upstate New York can grow grapes that should struggle this far north. The lakes absorb heat slowly through the summer, hold it deep into the cold season, and release it back into the surrounding slopes when frost would otherwise be more damaging. 🌊

That lake effect is one of the foundations of Finger Lakes wine country.

The Finger Lakes were carved and over-deepened by glaciers, leaving behind long, narrow basins with steep sides and enormous thermal mass. Around Seneca, Cayuga, and the other major lakes, that stored heat moderates the local climate just enough to matter. It can delay fall frost, soften winter cold, and reduce spring frost risk along the nearby hillsides. Those small temperature margins are invisible to most visitors, but to a vineyard, they can be the difference between survival and failure.

Seneca Lake is the clearest example. It is so deep and voluminous that it rarely freezes completely. Its last widely accepted full freeze was in 1912. That open water is part of why vineyards cluster along its shores and why the region became famous for cool-climate wines like Riesling, Gewurztraminer, Chardonnay, and Cabernet Franc.

The wine story goes back to the nineteenth century, when the first Finger Lakes vineyard was planted in Hammondsport in 1829. But the modern reputation of the region was transformed in the twentieth century, when growers proved that European vinifera grapes could survive and produce serious wine here.

That is the part most people miss.

Finger Lakes wine is not just a farm story.

It is a geology story.

The same glaciers that carved these lakes also created the conditions that made the vineyards possible. A cultural identity, an economy, and one of America’s most important cool-climate wine regions all depend on basins of water cut into the landscape thousands of years before anyone planted a vine.

What other place owes its entire identity to something that happened in deep time?

πŸ‚ For a short window each fall, the cottonwoods along the river arms and sheltered draws of Lake Sakakawea turn gold, and the western North Dakota breaks around them shift into rust, cream, charcoal, and ochre. For a place most Americans have barely heard of, the transformation is almost unreal. 🌊

Lake Sakakawea is one of the most overlooked fall landscapes in the Great Plains. Created by Garrison Dam on the Missouri River in 1953, the reservoir stretches for roughly 178 miles across North Dakota and holds more than 1,500 miles of shoreline. That size creates an entire world of bays, river arms, coulees, ravines, and long water corridors where autumn color appears in flashes instead of crowds.

The cottonwoods are the key. Plains cottonwoods have always belonged to the Missouri River bottomlands, where moisture, floodplain soils, and sheltered valley conditions allowed them to grow in places the open prairie could not. Around Lake Sakakawea, those trees still mark the old logic of the river country. They gather in draws, shoreline pockets, and protected bottoms, turning bright yellow against water and badland clay.

What makes the scene different from a mountain fall-color display is the contrast. There are no dense maple forests here. Instead, there is open sky, wind, reservoir water, exposed earth, and sudden ribbons of gold. The surrounding breaks and badlands give the whole landscape a harsher beauty, with eroded slopes glowing cream, rust, and brown under the low autumn sun.

Bald eagles add another layer to the season. The Missouri River system, including Lake Sakakawea, is important eagle country in North Dakota, and eagles are often associated with large lakes, rivers, open water, and mature cottonwoods. In fall, when migration overlaps with changing leaves and active fisheries, the reservoir can feel far wilder than its name recognition suggests.

And maybe that is the point.

Some places become famous because the world was taught how to look at them.

Others remain magnificent in near silence.

Lake Sakakawea in autumn is one of those places.

What overlooked landscape do you think deserves more attention?

🐟 Every September, adult Chinook salmon pass through the fish ladder at Bonneville Dam on their way back to the streams where they were born. The ladder exists because the dam blocked a migration that had been running for thousands of years and the federal government was legally required to mitigate the damage. It works imperfectly. It is better than nothing. The fish that use it are completing a journey that the dam made harder and the tribes that depend on them never asked to be made harder. 🌊

Bonneville Dam, completed in 1938 on the Columbia River at the head of the Columbia River Gorge, was the first large federal hydroelectric dam on the Columbia mainstem and established the template for the Columbia River power system that now includes fourteen federal dams on the mainstem and hundreds more on its tributaries. The dam's fish passage facilities, including the fish ladders that allow adult salmon and steelhead to pass upstream over the dam's 60-foot height, were required by the project authorization and represented the federal government's acknowledgment that the Columbia River's salmon runs, which supported tribal treaty fisheries guaranteed by the 1855 treaties and a commercial fishing industry of significant economic importance, had to be maintained despite the dam's obstruction. The fish ladders at Bonneville were the first large-scale salmon passage facilities on a major Pacific Northwest dam and became the technical and regulatory model for fish passage requirements at subsequent Columbia River dams.

The passage efficiency of Bonneville's fish ladders has been monitored continuously since the dam's construction, and the data collected there over eighty-five years constitutes one of the most comprehensive long-term records of adult salmon migration in the world. The numbers tell a complicated story. Bonneville's fish counts, which enumerate every adult salmon and steelhead that passes over the dam, show that the ladders work in the sense that substantial numbers of fish do pass, in the hundreds of thousands annually in good years.
They also show that passage rates are significantly below historical runs, that the fish that do pass must survive a gauntlet of additional dams, warm water, predation, and altered habitat that was not present before the dam system was built, and that the specific wild fish populations most dependent on the upstream habitat above Bonneville have declined in ways that the passage facility counts cannot reverse. The ladder gets the fish over the dam. What happens to them above it is determined by everything else the Columbia River system has become.

What do you think fish ladders at large dams represent in the broader context of the obligation that dam-building created toward the salmon runs and the tribal nations whose treaty fisheries depend on them, and is a fish ladder an adequate mitigation for a dam that blocks a migration that existed for ten thousand years?

πŸŒ… Lake Okeechobee is the largest freshwater lake in the American South, and it is in a state of chronic ecological crisis. It's water is too high in phosphorus from agricultural runoff. Its algae blooms are toxic. Its releases to the estuaries on both coasts are damaging those ecosystems. And the Herbert Hoover D**e that holds it back from the communities below has been rated as deficient infrastructure for decades. Everything about this lake is a management problem that has not been adequately solved. πŸ’”

Lake Okeechobee occupies a shallow depression in the South Florida limestone, its 730 square miles of surface averaging only nine feet in depth and reaching a maximum of twelve feet, a geometry that makes it more analogous to a wetland marsh than to the deep lake its size suggests. The lake is the hydrological center of the greater Everglades system, historically releasing water south through the sawgrass marshes toward Florida Bay in a slow, wide sheet flow that maintained the specific hydrology the Everglades ecosystem required. The development of South Florida in the twentieth century, including the drainage of the Everglades Agricultural Area south of the lake and the construction of the Herbert Hoover D**e around the lake's perimeter after the 1928 hurricane, fundamentally reorganized this natural system, converting the lake from the gravity-fed headwaters of a self-managing wetland into a managed water storage facility whose releases are controlled by the Army Corps of Engineers to balance flood control, water supply, agricultural irrigation, and environmental flow requirements that often conflict with each other.

The phosphorus problem at Lake Okeechobee originates in the Everglades Agricultural Area and the Kissimmee River basin north of the lake, where agricultural runoff from dairy farms, sugarcane fields, and vegetable operations enters the lake carrying dissolved phosphorus in concentrations that far exceed the threshold above which cyanobacteria blooms become a regular occurrence. The lake's shallow depth and warm Florida climate make it particularly susceptible to bloom formation once phosphorus levels are elevated, and the blooms that have become a near-annual feature of the lake's summer and fall seasons generate toxins that have closed recreational areas, affected downstream estuaries when bloom-contaminated water is released, and produced imagery of bright green toxic water covering the surface of the largest lake in the American South that has become one of the most recognized symbols of agricultural non-point source pollution in the United States. The solutions to the phosphorus problem are understood scientifically. Their implementation is constrained by the political economy of Florida agriculture and the specific legal protections that agricultural operations enjoy under state and federal environmental law.

What do you think an adequate solution to the Lake Okeechobee phosphorus crisis would actually require, and does your answer change depending on whether you are a South Florida resident, an Everglades ecologist, a sugarcane farmer in the Everglades Agricultural Area, or a Seminole Tribe member whose treaty territory includes the lake?

🦒 Every spring, tundra swans stop at Lake Winnibigoshish in northern Minnesota on their way to their Arctic breeding grounds, their arrival timed to the ice-out that opens the lake's shallow feeding areas to their long-necked diving. The Leech Lake Band of Ojibwe have been reading this lake's seasonal transitions for generations. The swans have been making this stop for longer than anyone has been keeping records. 🌊

Lake Winnibigoshish, called Winnie by Minnesotans who have been fishing it for generations, is the fourth largest lake in Minnesota, its 68,000 acres of shallow, wind-swept surface in the headwaters of the Mississippi River watershed making it one of the most productive walleye lakes in the upper Midwest and one of the most significant waterfowl staging areas on the Mississippi Flyway. The lake sits within the boundaries of the Leech Lake Reservation, home of the Leech Lake Band of Ojibwe, whose traditional territory encompasses the lake and whose relationship to its seasonal ecology predates the federal reservation system by many centuries. The Ojibwe name for the lake, from which Winnibigoshish derives, translates roughly as miserable wretched dirty water, a characterization that reflects not contempt but familiarity with the lake's tendency to become dangerously rough in the wind storms that cross its large, shallow surface without obstruction, a practical warning encoded in the name rather than an aesthetic judgment.

The annual ice-out on Lake Winnibigoshish is a significant ecological event that triggers a cascade of biological transitions across the lake and its surrounding watershed, the open water releasing the oxygen and light constraints that limit winter biological activity and allowing the spring productivity pulse that fuels the lake's fishery and wildlife resources through the growing season. The tundra swans that use Winnibigoshish as a spring staging area are among the most visible beneficiaries of ice-out timing, their arrival and departure keyed to the availability of the aquatic vegetation and invertebrates accessible in the lake's newly opened shallows. The specific timing of ice-out at Winnibigoshish has been recorded consistently enough over the past century that researchers use it as one of the more reliable long-term indicators of spring temperature trends in the upper Midwest, the date of ice-out moving earlier by a measurable amount over the past several decades in a pattern consistent with the regional warming trend documented in weather station data from the same period.

What do you think the measurable advancement of Lake Winnibigoshish's ice-out date over the past century tells us about the relationship between climate change and the specific seasonal timing that the biological communities depending on this lake have calibrated their annual cycles to, and what happens when the biological calendar and the climate calendar begin to diverge?

06/12/2026

πŸ’§ Harlan County Lake in Nebraska is the centerpiece of one of the longest-running interstate water disputes in the American West, a conflict between Kansas and Nebraska over the Republican River that has been in federal court repeatedly since the 1940s and that produced a Supreme Court decision requiring Nebraska to pay Kansas over a hundred million dollars for water it used in violation of their compact. The irrigation pivot is still running. The dispute is not settled. 🌊

The Republican River Compact, signed in 1943 between Colorado, Kansas, and Nebraska, allocated the Republican River's water among the three states based on estimated natural flows and established a framework for sharing the river's resources that was designed for a pre-irrigation, pre-groundwater-pumping agricultural landscape. What the compact's drafters did not fully account for was the relationship between surface water flows in the Republican River and groundwater pumping from the alluvial aquifer connected to it, a relationship that became critically important as Nebraska's High Plains irrigated agriculture expanded dramatically in the decades after the compact was signed. When Nebraska farmers pumped groundwater from wells connected to the Republican River system, they were effectively reducing the river's flow into Kansas in amounts that were not measured or accounted for under the compact's original framework, a deduction from Kansas's allocated share that Kansas argued violated the compact and Nebraska initially resisted acknowledging.

The legal reckoning for Nebraska's excess Republican River water use came in stages, beginning with Kansas filing an original action in the United States Supreme Court in 1998 that ultimately resulted in a Special Master's report and a 2003 consent decree requiring Nebraska to reduce its Republican River water use and account for the groundwater-surface water connection that the compact's drafters had not anticipated. Nebraska's continued excess use after the decree led to further Supreme Court proceedings and a 2015 judgment requiring Nebraska to pay Kansas $5.5 million in damages and $110.8 million in disgorgement of economic benefit, one of the largest monetary judgments in an interstate water dispute in American history. The judgment was paid. The underlying tension between Nebraska's irrigated agriculture and Kansas's compact allocation has not been fully resolved, because the aquifer that connects them does not recognize state lines and its response to pumping operates on timescales measured in decades rather than in the annual accounting cycles of compact administration.

What do you think the Republican River compact dispute tells us about the adequacy of mid-twentieth century water allocation agreements for managing twenty-first century water use patterns in a region where groundwater pumping, surface water flows, and interstate legal obligations are all connected in ways the original compact writers could not fully anticipate?

🌱 Spirit Lake in 2024 is not the same lake it was before Mount St. Helens erupted in 1980. It will never be that lake again. But forty-four years after the eruption sterilized it, geese are nesting on the log mat, trees are growing from the floating debris, and the water is supporting fish species that colonized it from tributaries that survived the blast. The lake did not recover. It became something else entirely. 🌊

Spirit Lake's ecological trajectory in the four decades since the 1980 eruption of Mount St. Helens has become one of the most intensively studied natural recovery experiments in the history of ecology, a unique opportunity to observe how a complex lake ecosystem reassembles itself from near-zero biological conditions when the physical chemistry of the lake and the surrounding landscape change simultaneously and dramatically. The immediate post-eruption lake was a hostile environment by almost any biological measure, its water temperature elevated by geothermal heat, its chemistry altered by the volcanic material that covered its floor, its pH and dissolved oxygen levels outside the range that most aquatic organisms can tolerate. The log mat that covered its surface in the first years after the eruption further altered the light regime of the water column beneath it. By any standard assessment of the immediate post-eruption conditions, Spirit Lake should have required decades to begin supporting complex biological communities.

What actually happened was faster and stranger than the initial predictions. Within years of the eruption, microbial communities had colonized the lake's altered chemistry and were beginning to process the volcanic organic material on the lake floor. Within a decade, invertebrate communities had established in sections of the lake where conditions allowed. Within fifteen years, salmonids were being documented in the lake, having colonized from the small tributary streams that had survived the blast and that provided access to the lake once water temperatures and chemistry recovered sufficiently. The log mat, rather than remaining a biological dead zone, began accumulating windblown organic debris, moss colonization, and eventually soil-forming processes that have converted much of its original surface into a floating wetland platform supporting a succession sequence that is, forty years later, beginning to look like the early stages of a floating forest. The lake that exists today is not a recovered version of the lake that existed before 1980. It is a genuinely new biological community, assembled from the organisms that survived the eruption, those that colonized from outside, and those that evolved their behavior and distribution in response to conditions that had no historical precedent.

What do you think the Spirit Lake recovery tells us about the relationship between catastrophic disturbance and ecological resilience, and does a landscape that recovers from a volcanic eruption by becoming something new rather than returning to what it was represent success, failure, or something that our existing frameworks for thinking about ecological recovery don't fully capture?

06/12/2026

🦟 Mono Lake's alkali flies are one of the most important food resources in the entire Pacific flyway, and the winter hatches that produce clouds of emerging insects above the lake surface are a biological event of extraordinary scale that almost no one outside the scientific and birdwatching communities knows is happening in the Eastern Sierra every January. The flies have been feeding the birds that use this lake for thousands of years. The Indigenous people who lived here ate them too. 🌊

The alkali fly, Ephydra hians, is among the most numerous insects in North America at certain times of year in certain locations, and Mono Lake is the most significant of those locations, its highly alkaline and saline water providing an environment that the alkali fly has specifically adapted to exploit. The flies complete their entire life cycle in and around the lake, their larvae living in the mineral-rich water and feeding on the algae and bacteria of the lake's unique ecosystem, their pupal cases attached to submerged rocks and tufa formations, their adults emerging in hatches of such density that historical accounts describe visitors walking along the shore watching the ground move as fly swarms shifted with the wind. The Kutzadika'a people, the Northern Paiute band whose traditional territory encompassed Mono Lake, harvested the fly pupae as a significant food source, collecting them from the rocks and shoreline where they accumulated in drifts of several inches in depth, roasting or drying them for consumption and for trade with neighbouring groups. The pupae were called kutsavi and were a substantial nutritional resource, their caloric value and ease of collection making them an important part of the Kutzadika'a diet and the basis of the people's name, which translates roughly as the fly pupae eaters.

The alkali fly's role in the lake's ecosystem extends well beyond its importance to the Kutzadika'a. The flies are the primary food source for the millions of shorebirds and waterfowl that use Mono Lake as a stopover during their migrations along the Pacific flyway, California gulls that breed on the lake's islands feeding their chicks almost exclusively on alkali flies during the summer nesting season, eared grebes staging on the lake in autumn consuming enormous quantities of both flies and the brine shrimp that share the lake's productive chemistry, and dozens of migratory shorebird species stopping at the lake specifically to feed on the fly accumulations at the water's edge. The conservation of Mono Lake's water level, won through the decade-long legal battle documented in its own chapter of the lake's history, was in significant part a conservation of the specific lake chemistry and shoreline habitat that makes the alkali fly's extraordinary productivity possible, making the legal victory that saved the lake a victory for the entire food chain that depends on it.

What do you think the Kutzadika'a people's intimate knowledge of the alkali fly's ecology, accumulated over generations of harvest and observation, might contribute to the scientific understanding of Mono Lake's biological systems, and what is lost when that knowledge is not incorporated into contemporary lake management?

A Georgia lake vanished in minutes and left 39 people dead. On November 5, 1977, the Kelly Barnes Dam above Toccoa Falls Bible College failed without warning, sending a 35 acre lake through the campus and nearby homes. Students, staff, and children were killed. The dam had been raised and modified without proper engineering oversight, and the disaster changed Georgia dam safety forever.
