BLM REA COP 2010 Range-Wide Status of Colorado River Cutthroat Trout (Oncorhynchus clarkii pleuriticus) - Streams The distribution and abundance of Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus; CRCT) have declined from historical levels over their entire range. For this CRCT assessment we used existing information provided by 48 fisheries professionals applied through a consistent methodology to assess the extent of CRCT historical range, their current distribution, including genetic status, and evaluated the foreseeable risks to 285 populations designated as "conservation populations" by management agencies. We estimated CRCT historically occupied about 21,386 miles of habitat in the western U.S. CRCT currently occupy about 3,022 miles of habitat in 51 of the 61 4th level HUCs historically occupied.
