Abstract
The study deals with the restoration of water quality of shallow, polluted, and eutrophic lakes. Dredging and removing of lake bottom sediments and introducing better quality water are the restoration measures explored. Vancouver Lake, Washington, was used as a test case. Hydrologic, hydrographic, hydrodynamic, and water quality information, provided by separate but correlated studies, was combined with the aid of mathematical simulation models. Dissolved oxygen (DO) was used as an indicator of the overall water quality in the system. In addition to the DO model, the aquatic life model for computing time-varying levels of phytoplankton and bacteria was also tried. The validity of these models was verified with the actual field data. After verifications of the models under the existing conditions, they were used to project and predict the water quality of Vancouver Lake as will be affected by dredged lake depths and introduced flows from the Columbia River.
