A history of restoration efforts for Vancouver Lake

Washington.
Vancouver Lake is rapidly dying as the result of both natural and man-made causes. The means are available to reverse this trend, but they require the firm commitment of area residents and the backing of advisory and regulatory agencies. Fortunately, past and present support for the rehabilitation of Vancouver Lake has been strong. The lake has been extensively studied, with the conclusion that due to Vancouver Lake's unique position, adjacent to two major municipalities and within the Columbia River floodplain, the rehabilitation of Vancouver Lake is feasible and would result in a primary recreational resource for Clark County.
The purpose of this study is the preparation of a Master Plan for the rehabilitation of Vancouver Lake. The findings of this investigation are in substantial agreement with the recommendations of Washington State University (WSU) and Stevens, Thompson, Runyan, Inc. (STR). The successful rehabilitation of Vancouver Lake should include the following three major activities:
- Flushing the lake with relatively clean Columbia River water.
- Dredging the alek to provide for recreational usage.
- Control of pollution entering the lake.
All three actions are essential if the lake is to be made safe and usable for swimming, boating, and other recreation.
In its present condition, Vancouver Lake is highly polluted. Present excessive pollutants include coliform bacteria, turbidity, and nutrients. Problems are compounded by the shallowness of the lake, an average depth of only 2 to 3 feet at mean low water. Flushing the lake with Columbia River water will greatly improve the aquatic environment of the lake, but should not be expected to create crystal-clear water. Water quality will reach a level intermediate between the existing condition and that of the Columbia River. Some turbidity and algae will remain. The concentrations of bacteria and other pollutants will be moderately low. Water temperatures will be slightly cooler than at present during the summer and warmer during the winter. The lake will be suitable for boating, sailing, fishing, and with minor additional effort--which could be provided by supplemental wells--for swimming along the beach area. Lake water quality will continue to improve as the quality of the Columbia River improves and as programs to reduce the influx of pollutants to the lake are implemented.
The proposed rehabilitation plan includes the construction of a channel and culvert system. The channel would extend from the Columbia River at Blurock Landing to Lower River Road, adjacent to the lake. The culverts would extend the flushing system beneath a transportation corridor and would discharge into the lake. The culverts would be equipped with sluice gates on the Columbia River side and with flap gates on the lake side. The flap gates woud prevent reverse flow out of the lake through the culverts. The sluice gates could, if necessary, be used to prevent inflow to the lake during periods of high turbidity in the river, to isolate the lake from migrating salmonids, and for lake maintenance. Four 96-inch diameter culverts are recommended to provide a sufficient volume of flow for the study plan.
