The purpose of the study is to assess the effect of removal of hatchery fish on the native trout populations of the McKenzie River. Hatchery fish stocking was discontinued on this section of river in 2010. Quantitative information about native trout in the lower McKenzie River is limited and existing literature suggests that ceasing hatchery trout releases leads to increased wild trout populations due to reduced competition and angling-related mortality. The Lower McKenzie Wild Trout Population Study (LMWTPS) was initiated in 2010 and is ongoing. 2012 marks the third year of data collection.
