Description Washington State’s Department of Ecology (Ecology) selected the Lacamas Creek watershed in 2010 for a water quality improvement project because segments of Lacamas Creek and its tributaries did not meet water quality standards for temperature, dissolved oxygen, and fecal bacteria. In addition, nutrient concentrations in the watershed are historically very high. Ecology conducted water quality sampling in 2010 – 2011 and published a summary of watershed groundwater conditions in 2013. In 2021, Ecology elected to conduct the water quality study as a Source Assessment study. Ecology staff also conducted additional bacteria sampling in 2021. This report summarizes the water quality data collected in 2010 – 2011 and 2021, presents a technical analysis of potential sources of pollution in the watershed, and outlines recommendations for improving the watershed’s water quality.
