ms have reduced distribution of the endangered Colorado pikeminnow Ptychocheilus lucius in the upper Colorado River basin: low-head diversion dams blocked upstream passage and large dams inundated free-flowing segments and cooled downstream reaches with deep-water releases. To date, range restoration efforts in the Colorado and Gunnison Rivers have focused on building fish ladders around diversion dams to allow recolonization of upstream reaches. Upstream thermal suitability for this warmwater cyprinid was assessed using temperature data and existing distributional information from river reaches where Colorado pikeminnow movements were unrestricted. Among-site thermal regime comparisons were made using mean annual...

We evaluated the thermal regime and relative abundance of native and non-native fish and invertebrates within Kelly Warm Spring and Savage Ditch, Grand Teton National Park, Wyoming. Water temperatures within the system remained relatively warm year round with mean temperatures less than 20 degrees Celsius near the source, and greater than 5 degress Celsius approximately 2 km downstream of the spring source. A total of 5 non-native species were collected; Convict/Zebra Cichlids (Cichlasoma nigrofasciatum), Green Swordtail (Xiphophorus hellerii), Tadpole Madtom (Noturus gyrinus), Guppies (Poecilia reticulate), and Goldfish (Carassius auratus). Non-native fish (Zebra Cichlids and Swordtails), red-rimmed melania snails...
FY2011Thousands of data points have been collected by Oregon Department of Fish and Wildlife and Nevada Division of Wildlife from the 1950s to the present describing the distribution of declining native redband and endangered Lahontan cutthroat trout, and the invasive, nonnative brown and brook trout. USGS analyzed this data to understand the climate-related changes to species distributions and model extinction risk. The results, submittedfor publication, will be used by the State of Oregon as it drafts conservation plans for redband trout and by the Nevada Division of Environmental Protection in drafting water quality criteria to protect and monitor the states coldwater fisheries.
