    NEW – CRWP Pollutant Load Modeling Tool (PLMT)

    The purpose of the Clackamas River Watershed Pollutant Modeling Tool is to provide an interactive framework for estimating the relative impacts of land use and best management practices on drinking water source quality in various parts of the watershed. This tool can be used to assess baseline conditions and consider scenarios for land management and pollution reduction in accordance with the Clackamas River Watershed Drinking Water Protection and Source Water Assessment Plans.  To access the tool go to

    River Watershed Agricultural Water Rights Project

    The CRWP worked with a Graduate student at Portland State to understand how many agricultural water rights are in the Clackamas River watershed, where they are and how large they may be, and if there are opportunities to work with these landowners under Oregon water law to put water back instream to increase river flows.  Check out the project Storymap here.

    Assessing Wildfire Risk to Municipal Drinking Water
