Nonnative, predatory lake trout and exotic whirling disease were introduced to the vast, seemingly secure Yellowstone Lake ecosystem, home to the largest remaining concentration of cutthroat trout. In the early 2000s the impacts of an expanding lake trout population and whirling disease coincided with that of drought, resulting in a precipitous decline in cutthroat trout. Cascading effects through the ecosystem have Hayden Survey camping near Yellowstone Lake in 1871. been documented.

  • Native Fish Conservation
    Yellowstone SScience Native Fish Conservation @ JOSH UDESEN Native Trout on the Rise he waters of Yellowstone National Park are among the most pristine on Earth. Here at the headwaters of the Missouri and Snake rivers, the park’s incredibly productive streams and lakes support an abundance of fish. Following the last Tglacial period 8,000-10,000 years ago, 12 species/subspecies of fish recolonized the park. These fish, including the iconic cutthroat trout, adapted and evolved to become specialists in the Yellowstone environment, underpinning a natural food web that includes magnificent animals: ospreys, bald eagles, river otters, black bears, and grizzly bears all feed upon cutthroat trout. When the park was established in 1872, early naturalists noted that about half of the waters were fishless, mostly because of waterfalls which precluded upstream movement of recolonizing fishes. Later, during a period of increasing popularity of the Yellowstone sport fishery, the newly established U.S. Fish Commission began to extensively stock the park’s waters with non-natives, including brown, brook, rainbow, and lake trout. Done more than a century ago as an attempt to increase an- gling opportunities, these actions had unintended consequences. Non-native fish caused serious negative impacts on native fish populations in some watersheds, and altered the parks natural ecology, particularly at Yellowstone Lake. It took a great deal of effort over many decades to alter our native fisheries. It will take a great deal more work to restore them. As Aldo Leopold once said, “A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic com- munity.

  • Mountain Lakes Guide: Absaroka, Beartooth & Crazies
    2021 MOUNTAIN LAKES GUIDE Silver Lake ABSAROKA - BEARTOOTH & CRAZY MOUNTAINS Fellow Angler: This booklet is intended to pass on information collected over many years about the fishery of the Absaroka-Beartooth high country lakes. Since Pat Marcuson began surveying these lakes in 1967, many individuals have hefted a heavy pack and worked the high country for Fish, Wildlife and Parks. They have brought back the raw data and personal observations necessary to formulate management schemes for the 300+ lakes in this area containing fish. While the information presented here is not intended as a guide for hiking/camping or fishing techniques, it should help wilderness users to better plan their trips according to individual preferences and abilities. Fish species present in the Absaroka-Beartooth lakes include Yellowstone cutthroat trout, brook trout, rainbow trout, golden trout, arctic grayling, and variations of cutthroat/rainbow/golden trout hybrids. These lake fisheries generally fall into two categories: self-sustaining and stocked. Self-sustaining lakes have enough spawning habitat to allow fish to restock themselves year after year. These often contain so many fish that while fishing can be fast, the average fish size will be small. The average size and number of fish present change very little from year to year in most of these lakes. Lakes without spawning potential must be planted regularly to sustain a fishery. Standard stocking in the Beartooths is 50-100 Yellowstone cutthroat trout fingerlings per acre every eight years. Special situations may call for different species, numbers, or frequency of plants. For instance, lakes with heavy fishing pressure tend to be stocked more often and at higher densities.

Detjens 1 and Alexander V. Zale 2 1 U.S. National Park Service, Yellowstone Center for Resources, Native Fish Conservation Program, P.O. Box 168, Yellowstone National Park, WY 82190, USA; [email protected] 2 U.S. Geological Survey, Montana Cooperative Fishery Research Unit, Department of Ecology, Montana State University, MSU–P.O. Box 173460, Bozeman, MT 59717-3460, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-307-344-2281 Received: 17 April 2020; Accepted: 4 June 2020; Published: 6 June 2020 Abstract: Preventing the interbasin transfer of aquatic invasive species is a high priority for natural resource managers. Such transfers can be made by humans or can occur by dispersal through connected waterways. A natural surface water connection between the Atlantic and Pacific drainages in North America exists at Two Ocean Pass south of Yellowstone National Park. Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri used this route to cross the Continental Divide and colonize the Yellowstone River from ancestral sources in the Snake River following glacial recession 14,000 bp. Nonnative lake trout Salvelinus namaycush were stocked into lakes in the Snake River headwaters in 1890 and quickly dispersed downstream. Lake trout were discovered in Yellowstone Lake in 1994 and were assumed to have been illegally introduced. Recently, lake trout have demonstrated their ability to move widely through river systems and invade headwater lakes in Glacier National Park. Our objective was to determine if lake trout and other nonnative fish were present in the connected waters near Two Ocean Pass and could thereby colonize the Yellowstone River basin in the past or future.

  • Visiting Lamar Valley & Tower Junction Area of Yellowstone
    ® Visiting Lamar Valley & Tower Junction Area of Yellowstone Lamar Valley is located in the northeast section of the park, just east of Tower Junction. Home to herds of elk, bison, and several packs of wolves, the Lamar Valley is Yellow - stone's prime location to view wildlife. The best time to see wildlife is in the early morn - ing or late evening. Lamar Valley has the largest concentration of grizzlies in the park, and with a little patience and a lot of luck, you may see one. Be sure to bring along a pair of binoculars or a spotting scope. Lamar Valley is the top destination inside Yel - lowstone Park for viewing wolves. There are also abundant fishing opportunities in the Lamar Valley. Mammoth Springs of Yellowstone Sites of Interest: 1. Tower Falls Overlook At present, there is a partial closure of the Tower Fall trail in effect that unfortunately re - stricts access to the bottom of the waterfall, and will for some time, in the interest of public safety. However, the upper platform at the top of the trail still provides historic views of the falls and remains open to the public. Starting at the parking area for the Tower Fall General Store, this trail leads approximately 100 yards to an overlook of the falls. From there it descends 200 feet (60 m.) via a series of switchbacks to the base of the 132 foot (40m.) fall, where the view is even more dramatic. Trailhead: Starting at the parking area for the Tower Fall General Store Round trip Distance: 1.0 mile (1.6 km.)
