Data Alert: 3 August 2023 There was an error in data loading of daily averages that resulted in mixed reporting of Water Quality Monitoring (WQM) and scroll case water temperature at multiple locations. Daily average forebay water temperature data downloaded from DART between 15 June 2022 - 2 August 2023 were impacted; data may have included scroll case measurements. Please contact DART Team, dart@cbr.washington.edu if you have any questions. We apologize for the mixed reporting of daily average water temperature values.
