A history of restoration efforts for Vancouver Lake

Cooper Consultants, Inc. 1985. Water Quality Effects of Dredging and Flushing at Vancouver Lake: draft report. Port of Vancouver.

The Vancouver Lake Restoration Plan is a three-point program to modify Vancouver Lake and its drainage in order to provid improved water quality in Vancouver Lake. The three parts of the program are: (1) Flush the lake with relatively clean Columbia River water ; (2) Dredge the lake to provide for recreational usage and distribution of flushing/dilution water ; (3) Control the pollution entering the lake.

The Vancouver Lake restoration project addressed the first two goals. The third goal is being addressed under the Clark County 208 comprehensive plan.

A water quality monitoring program was established as part of the Vancouver Lake restoration project to assess water quality effects of the dredging on Vancouver Lake, and to ensure that required water quality standards were met during construction. During the project, the monitoring program was expanded to attempt to assess the overall water quality changes in the lake subsequent to completion of dredging and operation of the flushing channel. This report details the findings of that expanded water quality monitoring program.

Highly turbid, dirty looking water, nuisance algal blooms and bacterial contamination were prime factors that reduced the recreational use of Vancouver Lake. The restoration program goals targeted these problems for improvement by reducing sediment resuspension through dredging, reducing bacterial contamination by controlling sources in Burnt Bridge Creek, and reducing algal growth by lowering the concentration of algal nutrients by flushing. Consequently, the water quality monitoring program emphasized parameters concerned with water clarity and algal growth.

Turbidity, suspended solids and phytoplankton (algae) density were measured regularly, as were the major nutrients required for phytoplankton growth-nitrogen and phosphorus. Algal species were identified and counted, because changes in the kinds of algae present in a lake can provide information about the water quality of the lake. In addition, several parameters, such as pH, conductivity, and dissolved oxygen were measured because they are either influenced by phytoplankton growth or they provide information about changes in the water resulting from the flushing.
