Description A psuedodynamic model of dissolved oxygen in the Snohomish River Estuary system from Possession Sound to river mile 20 was developed using the model WASP5 to simulate hydrodynamics and water quality. The model was calibrated using data collected in August and September 1993. The model predicted that natural conditions in a large portion of the estuary would be below dissolved oxygen standards under critical conditions. In addition,
part of the lower mainstem is projected to display oxygen deficits in exceedance of the 0.2 mg/L allowed by the standards when natural conditions are below the standard.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
