Henderson Inlet effectiveness monitoring
Our monitoring work in the Henderson Inlet watershed highlights how local government projects successfully reduced fecal coliform levels in water.
Thurston County, the cities of Lacey and Olympia, and Thurston Conservation District carried out a range of projects to tackle this water quality problem. These projects aimed to reduce potential sources of fecal contamination like residential wastewater, stormwater, pet waste, and agricultural runoff.
Meanwhile, we monitored water quality in streams throughout the Henderson Inlet watershed to study the effectiveness of these projects. We found that fecal coliform levels in Woodland and Woodard Creeks declined over the timeframe of these projects, despite increases in local population and development.
