This report presents water quality and stream channel morphology data from twenty-six monitoring stations in national parks in Oregon and Washington States. The dataset includes one station at Ebey’s Landing National Historical Reserve, three stations at Lewis and Clark National Historical Park, eight stations at Mount Rainier National Park, seven stations at North Cascades National Park, and seven stations at Olympic National Park. The report compares eleven years of data (2011–2021) collected by the National Park Service’s North Coast and Cascades Inventory and Monitoring Network to state water quality standards and criteria, where available. At twenty-five of the twenty-six stations network staff collected continuous air and stream water temperature data. In addition, at all stations staff collected annual measurements of core water quality parameters and channel morphology characteristics. Finally, staff conducted annual assessments of benthic macroinvertebrates at all stations. These macroinvertebrate data will be summarized in a separate report.
