The USGS will collect new information about the distribution, abundance, and movement of the finespotted Snake River cutthroat trout below Jackson Lake Dam and determine the effects of discharge, sediment accumulation, and off-channel habitat on cutthroat trout recruitment and survival. Data collected will be used to develop new insights into the management of this portion of the Snake River and potential for restoring some elements of ecosystem function that have been lost since the construction of Jackson Lake Dam. Project partners include the National Park Service, Montana State University, Utah State University, Wyoming Game and Fish, US Bureau of Reclamation, and the Teton Conservation District.
