An investment analysis that looked at how much it would cost water users to build and operate the proposed Temperance Flat Dam northeast of Fresno without government funding was
finished earlier this year and quietly passed among water districts, which just as quietly asked the federal government to shelve work on the project. Read More
A range-wide genetic analysis of Lahontan cutthroat populations in Nevada, California and Oregon done by Helen Neville, Trout Unlimited’s senior scientist and UC-Davis in 2018 turned up hybrids — a mix Lahontan cutthroat and rainbow trout — in Independence Lake samples. As one of only two lakes in the world to support a relict self-sustaining and naturally reproducing population of Lahontan cutthroat trout, a threatened species under the Endangered Species Act, Independence Lake is irreplaceable.
A century of fire exclusion from Caples Creek drainage has led to higher fuel loading and tree density, which has increased the risk of high intensity wildfire. An important community water supply serving 110,000 people in the El Dorado Irrigation District is threatened, and the condition of meadows, streamside corridors, and aspen stands has declined. This project will complete 25 miles of prescribed fire containment line in preparation for 8,800 acres of burning. The project includes 4,400 acres of lower elevation understory burning, 4,400 acres of burning in vegetative islands mixed with rock at higher elevation, 25 acres of aspen restoration activities, and 25 acres of meadow restoration activities.

The Caples fire occurred in 2019 as part of the Caples Watershed Restoration project. A controlled burn was initiated at the end of September and classified as a wildfire in early October. The Fire Behavior Assessment Team (FBAT) has been in operation since 2003 and is a Multi-agency group of Fire/fuels managers, and fire scientists. Their task is to collect fire behavior and fire effects data for various objectives and agencies.

Our iconic Snake River chinook salmon are down to less than 1 percent of their historic numbers.
With a few real exceptions, juvenile smolts in Idaho rear in some of the West’s best habitat, but on their way to the Pacific Ocean they must traverse eight dams, including four on the lower Snake River.
How do those dams impact their survival? A recent study used various approaches to estimate Snake River dam-related mortality and averaged their estimates with other comparable studies. The study confirms what scientists have been saying for decades. Read More
Wild summer-run steelhead in the Elwha were extinct before the dams came out. That’s right, extinct. Now – just six years after the dams were removed – hundreds of wild summer-runs have emerged, in all likelihood from the rainbow trout population that persisted above the dams, like a phoenix rising from the ashes.
No hatchery was used to produce summer-run steelhead. All it took was unimpeded access to the ocean for these amazing fish to reappear. And, let’s remember, this resurgence happened during a period of poor ocean conditions that have depressed other salmon and steelhead runs up and down the West Coast.
Nearly everyone agrees that Western rangelands will produce even larger and more frequent wildfires in the future. But are engineered fuel breaks the best answer?
Jack Williams, a scientist who worked for multiple federal agencies and Trout Unlimited says, “The primary culprit for larger fires in the Great Basin is cheatgrass, but warming temps compound the problem. Creating periodic firebreaks would help by breaking up and slowing down the flames. We can do that in a way that benefits the natural systems by expanding riparian and wet meadows along our small streams.”
The answer may be a small dose of much less expensive firebreaks and, surprisingly, strategies involving cows and beavers. Ranchers who fence streamside areas and/or rotate cows to rest pastures occasionally and allow streamside vegetation to grow back help re-establish natural firebreaks of lush green vegetation.
The Pebble mine would be one of the largest open pit gold and copper mines in the world and multiple times larger than every hard rock mine in Alaska combined. This would be an open-pit mine, recovering low-grade copper, gold and molybdenum. It would create a mountain of overburden containing the exact ingredients to produce sulfuric acid and result in a massive toxic tailings pond that will require intense water treatment and maintenance forever.
Pebble Mine would not simply be an open-pit mine. More accurately, the Pebble Mine would be a twisted serpent of ecological and irreparable impact culminating at the head with one the largest mines in the world and fangs full of toxic tailings and sulphuric acid for venom. Help stop the snake before it bites us. Please comment today.
The objective of many BLM management efforts is to shift streams that have been degraded by stressors such as drought, wildfire, and historical grazing practices from a non-functioning designation to a proper functioning designation, and then make sure they stay that way. But how exactly do you do that, especially for such a massive landscape?
Land managers are increasingly turning to two natural approaches to restore degraded riparian areas and improve stream habitats, a one-two punch involving grazing management and beaver. New research led by TU scientists and BLM biologists shows just how effective these can be. Read More
A new study commissioned by a Bristol Bay seafood marketing group paints a doomsday scenario if the bulk tailings dam at the proposed Pebble mine ever suffered a catastrophic breach, an outcome the U.S Army Corps of Engineers has called very remote and one the mine developer has taken steps to avoid.
Billions of gallons of mud would smother valley bottoms, covering vast stretches of salmon habitat, according to an executive summary released Friday. Finely ground-up waste material from mining would travel downstream and spill into Bristol Bay more than 200 river miles from the mine site, threatening the valuable salmon fishery.
“Given the fine-grained nature of the material, it is extremely likely that these tailings would continue to Bristol Bay, where they would eventually settle out in the Nushagak River estuary,” the summary says.
