A history of restoration efforts for Vancouver Lake

Envirosphere Co. 1983-1985. Vancouver Lake Fisheries Catch Data Report for ...

State and federal fisheries agencies have expressed concern over the effect of the Vancouver Lake Restoration Project on fisheries resources of the Columbia River. Of particular concern was whether the Vancouver Lake flushing channel would divert juvenile salmon and trout, which utilize the Columbia River as a nursery area and migration pathway, into the lake where they could become disoriented and incur increased mortality from predation or adverse water quality or both. Columbia River water flowing through the lake and out via Lake River may attract upriver migrating adult salmon and trout into the lake. This would cause migration delays and possibly mortality. Concerns were also expressed over the effect of increased flushing and dredging of the lake on resident warm-water fish species, important to local sport fishermen.

1982: A fisheries monitoring program was designed to address the major agency concerns. This report briefly describes methods and major findings for studies completed between April and December 1982 and makes recommendations for further study. The scope of the 1982 study differed from that originally planned because the flushing channel's opening was delayed and, surprisingly, juvenile Chinook salmon were encountered rearing in the lake. Originally only one survey was planned prior to opening the flushing channel, and its purpose as to characterize the lake's resident fish population. Because of the discovery of juvenile Chinook in this survey, additional surveys were planned to monitor these fish to see how long they stayed in the lake and how they fared in relation to feeding success and to seasonally increasing water temperatures. It was not until November 1982, in conjunction with the opening of the flushing channel, that the monitoring program returned to the original schedule.

1983: A fisheries monitoring program was designed to address the major agency concerns. This report briefly describes methods used, tabulates fish catches by location and date, and discusses the disposition of the catch for the sampling period of January to December 1983. The 1983 study followed the original scope of work with some modifications. Because of the delay in opening of the flushing channel (from June 1982 to October 1982), the 1983 program was the first year of sampling the lake during peak periods of downstream juvenile Chinook salmon migration with the flushing channel in operation. Also, due to the low number of juvenile Chinook salmon entering the lake during June and July by way of the flushing channel, a mark and recapture program was not undertaken in the lake as originally planned.

1984: A fisheries monitoring program was designed to address the major agency concerns. This report briefly describes methods used, tabulates fish catches by location and date, and discusses the disposition of the catch for the sampling period to the end of the project, January through September 1984. the 1984 study followed the original scope of work with some modifications. Because of the delay in opening of the flushing channel (from June 1982 to October 1982), the 1984 program was the second year of sampling the lake during peak periods of downstream juvenile chinook salmon migration with the flushing channel in operation.
