Cascade Monitors Stormwater Treatment Wetlands

A new video produced by Clackamas Water Environment Services (WES) features Cascade Environmental Group staff Todd Alsbury and Simon Apostol as they perform fish sampling in Carli Creek, a tributary of the Clackamas River and the site of significant restoration efforts by WES.

Since 2018, the innovative Carli Creek Water Quality Project has been filtering harmful pollutants from stormwater runoff from surrounding industrial properties before it reaches Carli Creek and the Clackamas River. In addition to surveying the restored stream for native fish species, Cascade has been assisting WES in monitoring the wetland treatment cells and riparian areas for compliance with U.S. Army Corps of Engineers and Oregon Department of State Lands permits and mitigation performance standards. Cascade has teamed with Mosaic Ecology on this project, Mosaic is maintaining the site to ensure the site achieves the native plant cover goals.
