Watershed Health & Watershed Action Planning

We've transitioned our stormwater management program from a regulatory-driven approach to stormwater management. Our focus is on improving overall watershed health. This integrated approach is focused on four main components:

  • Hydrology
    Managing stormwater runoff in a manner that minimizes flooding and stream channel degradation
  • Water Quality
    Reducing in-stream contaminants
  • Habitat
    Promoting the function and/or restoration of functioning and healthy streams and riparian areas
  • Biological
    Maintaining viable aquatic insect and diverse fish and wildlife populations

RiverHealth Stewardship Program

The RiverHealth Stewardship Program offers grants to support community groups, businesses, and property owners who want to improve the health of watersheds within the surface water areas served by Water Environment Services. See the Grant application and guide for forms and program details, including eligibility and project ideas. For questions, contact Gail Shaloum at 503-742-4597 or gshaloum@clackamas.us

The grant application process is open February through mid-April annually.

Watershed Action Plans

We initiated Watershed Action Plans in the Kellogg/Mt. Scott and Rock Creek basins. The goal of these plans is to develop basin-specific strategies for watershed management.


We conduct a long-term monitoring program to evaluate stream health in its surface water areas. The comprehensive monitoring program began in 2009, although we've sampled macroinvertebrates since 2002.

Geomorphic monitoring reveals the impacts associated with hydromodification, or the change in stream habitat caused by urban runoff. Macroinvertebrate monitoring indicates the impacts on ecological systems. This information is useful for the prioritization of stream restoration projects and watershed management efforts.
