| Description |
This document is the second Addendum to Quality Assurance Project Plan Effectiveness Monitoring of Water Stargrass Harvesting Operations, lower Yakima River. The primary goal of this work is to collect temperature, dissolved oxygen, and streamflow velocity data at two pilot treatment locations before and after harvesting of aquatic biomass. Treatments of the pilot locations will occur during the 2021 - 2023 growing seasons in late spring to early fall which also coincides with irrigation season, baseflow conditions, and salmon migration. In addition, two nearby control (unharvested) areas will be monitored to help evaluate harvesting effectiveness. We anticipate harvesting up to one acre of aquatic biomass at each of the two harvesting locations on the mainstem lower Yakima, near Benton City, WA. |
