Abstract: Stonecats are only found in restricted sections of two river drainages, the St. Vrain River near Longmont, CO and the Republican River near Wray, CO (Figure 1). They are found in riffle and pool sections of warmer rivers and are intolerant of water pollution derived from agriculture (Gammon and Gammon 1993; Duehr et al. 2006) and increased suspended solids (Bergstedt and Bergersen 1997). In the St. Vrain River, stonecats overlap with common shiner populations, which currently have special protection from thermal pollution through a Tier-1 Warm Water thermal standard (Regulations #31 and #38, WQCD). My study is aimed at determining whether this standard is also protective for stonecats.
