Rivers across Alaska are turning orange, and scientists think thawing permafrost is likely the cause.
The results come from a @USGS and @NatlParkService survey of “rusting” streams, plus satellite observations from @NASA and others.
In the Aleutian communities of Area M, fish are far more than a resource - they are life and survival.
For many rural families, fish are the only dependable subsistence food source. State fishery decisions aren’t abstract policies passed in faraway rooms; they shape everyday meals, family traditions, local jobs, and food security in villages that rely on healthy fish runs to sustain them.
Aleut's new documentary 'Anchored Here' brings these realities into focus. Through the voices of fishermen, elders, and community members, they reflect on how decisions carry real consequences.

"...Communities in northwest Alaska that are removed from roads depend on fish, large ungulates and marine mammals that are now in danger, the report concludes."
"Researchers documented a loss of fish species like Dolly Varden and Slimy Sculpin as the minerals shifted the water quality. The loss of fish also coincided with a steep decrease in benthic macroinvertebrate diversity and periphyton biomass, according to the research...."
"...Waters that were observed as transparent in June 2017 turned to a burnt orange in the summer of 2018....Waters that display a change in color also see a decrease in stream biodiversity...."
"Now, high-latitude fish species, like Pacific salmon, Dolly Varden and Arctic grayling, are at risk of losing habitat due to the disbursement of iron and toxic metals in Arctic streams in northern Alaska, according to the study...."
Alaska’s diverse ag background is supporting job creation and sparking our economy. I was happy to bring Senator John Boozman to a kelp farm in Kodiak, where their innovative practices are employing folks and making a great Alaskan product.
@HeidiDrygas About 10 yrs ago, we came across two deer swimming in the ocean when commercial fishing. It was wild. We slowed down, circled them, and tried to get them pointed in the direction of the nearest shore. Eagles swimming are another wild sight!
