This fish barrier was on Coulee Creek, a tributary to the Spokane River. This total barrier blocked access to 32.13 miles of habitat for native redband rainbow trout. There are 4 crossings downstream of the barrier and about 26 crossings upstream. The original crossing with three barrier culverts was replaced with a 40 foot long steel bridge and fish passage has now been restored. Heavy agricultural influences in the upper watershed have been identified as contributing to the channel degradation, however the channel does appear to be recovering, as evidenced by riparian vegetation, point bar deposition and building of a small active floodplain inside the incised channel. According to a study titled "Baseline Assessment of Fish Species Distribution and Densities in Deep and Coulee Creeks" and "A Genetic Assessment of the Wild Rainbow Trout Populations in Select Tributaries of Latah (Hangman) Creek and the Middle Spokane River," published in 2005 by Jason McLellan of WDFW, "the results of the genetic analysis indicated that the rainbow trout in Coulee Creek are likely genetically pure, native redband rainbow trout."
