As a stakeholder in your watershed, do you know how your needs inter-relate with the needs of other watershed stakeholders? Increasing demand for water among public, industrial, and agricultural users threatens to reduce streamflow in many watersheds, but the impacts of competing demands on flow rates can be unclear. The HDSS process will produce more data, classifications relevant to all stakeholders, and reviewable documentation to support more robust and flexible instream flow models. Improving modeling results can help balance competing stakeholder needs with healthy stream ecosystems.
