Pyramid Lake in Bloom

Dense bands of blue-green algae, or cyanobacteria, swirled around the waters of Pyramid Lake in October 2024. This western Nevada lake experiences similar blooms on an almost-yearly basis. The proliferation of single-celled, photosynthetic organisms in autumn 2024 became one of the most active bloom events seen in years, according to the Pyramid Lake Paiute Tribe Water Quality Program.

The OLI-2 (Operational Land Imager-2) on the Landsat 9 satellite acquired this natural-color image of the bloom on October 8. One day earlier, the Pyramid Lake Paiute Tribe noted that bloom activity was increasing with water conditions favorable for phytoplankton growth, and the lake water was becoming more opaque in some areas. The bloom continued to expand and discolor the water and may have reached its peak around October 15.

A San Francisco Estuary Institute water quality analysis tool showed that levels of sunlight-harvesting chlorophyll-a and an index estimating cyanobacteria concentration both increased between late September and mid-October. These estimates were derived from an ocean color instrument on the European Space Agency’s Sentinel-3 satellite mission with additional processing by the NOAA National Ocean Service.

According to the Pyramid Lake Paiute Tribe, the autumn 2024 bloom contains the cyanobacteria Nodularia spumigena. Nodularia species are nitrogen fixers common in warm, brackish waterbodies. Recurring Nodularia blooms have been documented for decades in Pyramid Lake, including by Landsat satellite observations and in situ measurements.

Nodularia spumigena has the potential to produce toxins such as nodularin, which can affect the liver and cause other adverse health effects in humans. It may also bioaccumulate in aquatic vertebrates and invertebrates. The tribe reported on October 15 that the bloom was releasing toxins and advised people to avoid contact with the water. It may take two to three weeks from the peak of the bloom for water conditions to return to normal, they said.

Pyramid Lake is located in a remote desert area about 35 miles (56 kilometers) northeast of Reno, Nevada, and is fed primarily by the Truckee River. It is a remnant of the ancient and much larger Lake Lahontan, which formed during the last ice age when the regional climate was significantly cooler and wetter. Scientists believe Nodularia was part of the ecosystem going back to the days of Lake Lahontan.

Today, Pyramid Lake may be best known for its striking calcium carbonate formations known as tufas, as well as its fishery. The waterbody is the only remaining habitat for the endangered cui-ui (Chasmistes cuius), a large, long-lived suckerfish. It was also home to the world record-setting Lahontan cutthroat trout (Oncorhynchus clarkii henshawi), a 41-pounder landed in 1925.

Strange salmon So after the Pink salmon I promised some bonus fish, and here they are! These three were also featured on the poster. They’re all a bit unusual; they’re either a salmon but don’t behave like one, or vice versa. In order they are:

Steelhead (Oncorhynchus mykiss irideus) Also known as: Rainbow, redband (trout)

Steelhead are the anadromous form of the Rainbow trout. Meaning they, just like salmon, live at sea but are born and return to spawn in freshwater. However, unlike salmon, they don’t die afterwards. After regaining their strength at sea they may return multiple times, and Steelhead as old as 11 years have been found spawning. Unlike regular rainbows these fish develop very salmon-like heads when spawning, with long faces and slight kypes. Their beautiful spotting is very fine and unusually regular on the tail. This unique patterning is always present and can be used to identify them even at sea. Thanks to the rich marine environment, Steelhead grow big: 48" (122 cm) and 55 lbs (25 kg) is maximum, but 20-30″ (50-75 cm) and 5-20 lbs (2.5-9 kg) average. 

Coastal cutthroat trout (Oncorhynchus clarkii clarkii) Also known as: Sea-run cutthroat, Harvest (trout)

Coastal cutthroat are the anadromous form of the regular Cutthroat trout. Unlike Steelhead and Pacific salmon, Cutthroat do not make lengthy migrations out to sea. Often they just hang out in estuaries for a few months, spending much of the rest of the year in freshwater. Not all upriver migrations are to spawn either; sometimes they just want to overwinter or feed. When fresh out of saltwater Cutthroat can be quite silvery, with pale throat slashes. But as they approach spawning they become more and more yellow and the slashes that give them their name more pronounced red. Coastal cutthroats don’t grow very big: 24″ (60 cm) and 8 lbs (3.5 kg) is the recorded maximum, but average is 10-16″ (25-40 cm) and 1-5 lbs (0.5-2 kg). 

Kokanee salmon (Oncorhynchus nerka) Also known as: Kennerly’s salmon/trout, Kokanee trout, Silver trout, Little redfish, Kikanning, Walla Kokanees are the landlocked form of the Sockeye. Instead of venturing to sea, they spend most of their time in lakes, swimming upriver from them to spawn. Their pocket size and habitat should make identification easy enough. Interestingly, they often bear spots on their back and tail, something Sockeyes never have. The red on their gill covers can also be more extensive. The comparatively nutrient poor lake environment keeps Kokanees at an almost dwarf size compared to Sockeyes. Maximum size is 20″ (50 cm) and 6.25 lbs (3 kg), but don’t expect more than 9-12″ (23-30 cm) and 1-3 lbs (0.5-1 kg) on average.

Why Forests Need Salmon

(Originally posted at my blog at https://rebeccalexa.com/why-forests-need-salmon/)

One of my favorite fall activities is to check local streams for salmon runs. Here in the Pacific Northwest, and extending north into Alaska, we have seven species of anadromous Salmonidae: chinook salmon (Oncorhynchus tshawytscha), chum salmon (Oncorhynchus keta), coho salmon (Oncorhynchus kisutch), sockeye salmon (Oncorhynchus nerka), pink salmon (Oncorhynchus gorbuscha), coastal cutthroat trout  (Oncorhynchus clarkii clarkii), and steelhead (Oncorhynchus mykiss). My favorite run is the chum salmon that run up Ellsworth Creek in southwest Washington each fall, but I’m honestly just happy to see any migrating salmon. And as I hike through stands of ancient western red cedar (Thuja plicata), I like to think about the many ways in which these and other forests need salmon for their ongoing health.

Anadromous fish are those that are born in fresh water, spend much of their adult lives in salt water, and then return to fresh water to spawn. Some, like Atlantic salmon (Salmo salar) and some populations of American shad (Alosa sapidissima) are iteroparous, meaning they can make this journey multiple times in a lifetime. Pacific salmonids, on the other hand, are semelparous, meaning that they spawn once and then die shortly thereafter. (From here on out I am going to use “salmon” as a general, casual term referring to both the Oncorhynchus species, and the steelhead and cutthroat trout.)

Pacific salmon were originally freshwater fish that inhabited lakes and slow-moving rivers. Somewhere around 25 million years ago, the climate cooled significantly, with average temperatures dropping almost twenty degrees F. We’re not sure at what point after this the salmon began expanding into brackish estuaries and then the Pacific Ocean itself, but when they did they found rich sources of food unlike what they had access to in fresh water. Over time, they evolved a life cycle that let them be born in the relatively safe shelter of freshwater streams, and then go out to the ocean to feast on the banquet found there when they were large enough to have a better chance of survival.

Eventually salmon runs could be found in streams as far inland as eastern Idaho, eastern British Columbia, and the southern two-thirds of Alaska (with some Alaskan runs even crossing over into Canada!) And until the arrival of European colonizers, these streams consistently provided indigenous people all along the Pacific coastline an incredibly important source of food, cultural and economic trade, mythos, and more. Unfortunately, the newcomers overharvested the salmon, dammed and destroyed streams and other habitat, and of course spearheaded the causes of anthropogenic climate change.

Indigenous people fish for salmon at Celilo Falls on the Columbia River. As the single longest continuously inhabited community in North America (over 15,000 years!), this location was a home and hub of cultural activity for many indigenous tribes and communities across the region before it was flooded by the completion of the Dalles Dam in 1957.

All these factors have led to a precipitous decline in the size of both salmon runs, and the salmon themselves. This isn’t just detrimental to indigenous communities, though. It also threatens the health of forests all throughout the salmons’ range.

A forest isn’t just made of trees. It’s composed of entire plant communities, fungi (including mycorrhizal species), and the animals, bacteria, and other living beings that share space with them. When salmon travel up and down the waterways as fry, and then later to spawn as adults, they have a direct impact on that ecosystem.

Salmon fry are an important source of food for larger fish, amphibians, birds, and other beings that seek food in the water. In fact, part of why salmon lay so many eggs (over 5,000 in the case of chinook!) is because most of the fry that hatch will never make it to adulthood. But adult salmon aren’t safe from predation on their return trip to their birthplaces. In fact, they are caught and eaten by a wide variety of animals from bears to eagles, wolves to osprey, sea lions to bobcats.

Bears are of particular interest here. Brown bears (Ursus arctos) are well-known for gorging on summer and fall salmon runs to build up massive amounts of fat in preparation for winter hibernation. (Katmai National Park even celebrates their bears during Fat Bear Week every October!) You can watch video feeds of several bears hanging out in their favorite fishing spots by waterfalls and in the flow of the river.

Imagine that you are a young bear, perhaps recently forced to independence by your mother who is now focused on your younger siblings. You have to not only start catching fish without her protection from bigger bears, but you also need to make sure those stronger bears don’t steal your catch. What’s the best thing to do? Run far away into the woods to eat your salmon in peace, then leave the remains among the trees and head back for more.

If the fishing is good, bears will often eat only the fattiest parts of the salmon like the brains and skin, and then leave the rest behind for scavengers. The nutrients in the salmon then disseminate throughout the forest, whether carried in the digestive systems of animals, or broken down in place by decomposers. This helps make the nutrients available to the plants, particularly trees which may store massive amounts of nutrients in their trunks; when the trees die, they essentially become a food pantry for younger beings like new seedlings, fungi, and so forth.

Now–what’s so special about the nutrients in salmon? Well, remember that these fish spend years out in the ocean. And the ocean has an entirely different balance of nutrients floating around in it compared to what’s found in fresh water or on land. The salmon are essentially the only way these ocean-borne nutrients can make their way into the forest in any meaningful amount, and they do so on a regular basis each year. The trees near salmon runs fished by bears may be 300% larger than usual, and salmon also provide nearly three quarters of the nitrogen in the forest. That’s a pretty impressive contribution!

This isn’t just about how forests need salmon; it’s a reciprocal relationship. While the salmon’s immediate habitats are aquatic, these streams, rivers, and other waterways are directly affected by what happens on the land around them.

Every waterway has a watershed–an area of land from which precipitation drains into that waterway. These watersheds nest within each other; the watersheds of small streams are nested within the watersheds of the rivers the streams feed into. That water carries things with it, from soil to pollutants. So the health of the land has a direct impact on what is found in the water.

But it goes beyond what’s washed downstream, and into how it’s washed down. In a healthy forest, for example, the soil is able to absorb a significant amount of precipitation that falls throughout the year, keeping it from simply cascading down hillsides to create flooding and landslides. Water is also stored in the various living beings in the forest; again trees are often the champions with their great size, but smaller plants help with water retention quite a bit as well, both through internal storage and preventing evaporation from soil. A forest that is badly damaged, such as through a clearcut or wildfire, won’t hold water as well. This can lead to floods, landslides and other erosion, and increase the impact of summer droughts as the land simply can’t store as much water, or for as long.

All of this affects the salmon directly. If the watershed is no longer holding and releasing snowmelt, rain, and other water in a controlled manner, this can lead to flooding in waterways which can wash away salmon eggs and fry. Increased erosion buries the gravel that salmon lay eggs in with silt, smothering the eggs so they never hatch. When a riparian zone–the land along a waterway–is stripped of vegetation, the water loses crucial shaded areas that keep temperatures cool. Salmon easily overheat when temperatures rise even a few degrees. And drought can dry up smaller streams, stranding and even killing young salmon while preventing adults from reaching their spawning grounds.

While not every single salmon run exclusively travels through forests, many of them do. And many spawning grounds are found in forests, or at least areas with significant tree cover in riparian zones. Salmon must have healthy forests in order to continue to survive, and the loss of these forests is just one of many factors contributing to their severe decline.

Thankfully, I am far from the only person concerned about the safety of our wild Pacific salmon. There are numerous organizations working to protect and restore salmon habitat through dam removal, preservation and restoration of aquatic habitat and surrounding land, regulations on salmon fishing, and educating people about sustainable seafood options (or just not eating seafood at all.) And even habitat restoration efforts that aren’t directly in salmon-inhabited waterways still have a positive impact on the forest ecosystem as a whole.

We know that forests need salmon, and salmon need forests. To protect one is to protect the other, and long may they both thrive.

Heard the news about the dramatic new revision and understanding of cryptic subspecies of cutthroat trout, which complicates and changes how the US will approach preservation of the threatened greenback cutthroat? Essentially, the “greenback cutthroat” represents at least 2 distinct cryptic lineages of cutthroat trout, and Euro-American land management agencies had been rehabilitating the wrong fish.

“A cutthroat trout, once thought to be one of the true greenback cutthroat (Oncorhynchus clarkii stomias) feeds at the surface of a lake in Rocky Mountain National Park.” From Lindsay Fendt, for bioGraphic: “Resurrecting the Greenback, Take Two: After a case of mistaken identity, scientists face an upstream swim to save a fabled fish” (February 2019).

-

Despite all the attention that local land management agencies, outdoor recreation resort towns, and ultra-rich fly-fishing guide shops give to the “economic importance” (gross) of native cutthroat trout specifically, I still haven’t seen that many local land management agencies update distribution maps of cutthroat subspecies to reflect this pretty exciting research originally published in 2012. This is especially exciting to local enthusiasts of ecology, because the greenback cutthroat (Oncorhynchus clarkii stomias) is one of the most famous of the cutthroat subspecies; the greenback subspecies is Colorado’s formal “state fish” and was apparently understood to be endemic to waterways east of the Continental Divide, along the Front Range near Denver and Colorado Springs, making it one of the only cutthroat subspecies that lives in close proximity to the Great Plains. But it turns out that the greenback cutthroat is more diverse than originally thought. Basically, aside from the 3 known subspecies of cutthroat in Colorado, it seems that there were several (3) other cryptic lineages of cutthroat trout hanging out in the Colorado Rockies, but this has been difficult to detect because of how Euro-American land managers diluted native trout populations throughout the 20th century by stocking Colorado rivers with what they thought were the same subspecies (but were actually different subspecies) of cutthroat from different Colorado watersheds.

-----

This is important because it complicates the way that US agencies and Euro-American land management institutions were trying to remove protections for the greenback cutthroat. I highly recommend checking out Fendt’s great article. Here’s an excerpt:

It’s early October in northern Colorado, and aspen leaves are falling in droves onto the surface of West Creek, a small stream that flows through Rocky Mountain National Park’s southeast corner. Rain from the night before has cast a perfectly formed rainbow across the sky and is feeding an invigorated flow of water over the stream’s rocks. The backcountry scene is undisturbed aside from three men slowly plodding along the stream, their equipment emitting a rhythmic beeping over the sounds of the gurgling creek. Wading in the water is Chris Kennedy, a fish biologist with the U.S. Fish and Wildlife Service. [...]  As they make their way upstream, the men fill a bucket with a species of trout that Kennedy’s team had painstakingly stocked in the stream in previous years. At the time, the trout were thought to be greenback cutthroat trout (Oncorhynchus clarkii stomias), a critically threatened native subspecies that is also Colorado’s state fish. West Creek was one of more than a dozen sites where non-native fish were poisoned and removed to make way for greenback stocking, part of a 30-year, multi-million-dollar effort to restore the fish to its native range. The greenback was well on its way to being removed from the endangered species list when new genetic research changed the game. It turns out, the fish in Kennedy’s bucket aren’t greenbacks but a closely related cousin, a fish that was never actually native in these waters — and is abundant elsewhere.

Basically, Euro-American land managers had been rehabilitating the wrong fish.

-----

There were, up until this past decade, 9 recognized living subspecies of cutthroat trout.

Here are the 9 traditional subspecies:

-----

From the original 2012 research, by Metcalf et al, here is the “traditional” understanding of cutthroat biogeography in the Colorado Rockies, where it was presumed that there were 3 living subspecies and 1 extinct subspecies (O.c. macdonaldi):

And here is the new understanding, where the subspecies known as the Colorado River cutthroat (O.c. pleuriticus) is actually 3 separate cryptic lineages, and the subspecies known as the Greenback cutthroat (O.c. stomias) is actually 2 separate lineages.

-----

Here’s how cutthroat subspecies from west of the Continental Divide were introduced to watersheds east of the Divide:

-----

These maps come from the original article; the research was published here:

But there are also some shorter summaries available:

Excerpt: “With the insight afforded by the historical data, we now know with a great deal of certainty what cutthroat trout strains were here in Colorado before greenbacks declined in the early 20th century,” said Andrew Martin of CU’s ecology and evolutionary biology department. “And we finally know what a greenback cutthroat trout really is.”

Again, highly recommend Fendt’s article.

I just got result 'You are a Coastal Cutthroat trout! (Oncorhynchus clarkii clarkii)' on quiz 'What Pacific Northwestern Salmonid are You?'.

Honestly I'm pretty pleased with this. I think it's pretty accurate to me. Of course I'd take a test for salmon and come out a trout.

[shadow-of-fear-and-doubt]

What Pacific Northwestern Salmonid is your muse?

Your Result: You are a Coastal Cutthroat trout! (Oncorhynchus clarkii clarkii)

What the heck? You're a trout? Bet you didn't expect that! Well here's the twist- the only thing separating most trout from salmon is their behavior- they're in the same genus. Most cutthroat trout prefer inland rivers and lakes, and will never set fin in the ocean, but you are different; you dare to dream...though you're still a little nervous about it! While you prefer to spend time on the coast instead of upstream, you're not really ready to go too far out into the ocean- and you prefer to spend the cold winters cozy in a stream. It's ok, though, you're already seeing horizons most cutthroat trout will never see- and you've got one up on your salmon friends: you won't die the moment you find love.
