Missing Data: Covid, High Spill, Low Fish Detection Results In Lack Of 2020 Juvenile Salmonid Survival Estimates From Upstream Dams To Below Bonneville

Every year about this time, NOAA Fisheries releases a memo detailing preliminary survival estimates for passage of spring-migrating juvenile salmonids through Snake and Columbia River dams – key data for assessing the impact of federal hydropower operations on 13 species of salmon and steelhead listed under the Endangered Species Act. This year, however, due to Covid-19 impacts and more spill for fish, that data took a hit.
