Bibliography of Vancouver Lake watershed, including Burnt Bridge Creek, Flushing Channel, Lake River, and Salmon Creek

A history of restoration efforts for Vancouver Lake

Jeane, G.S. (to D. Burkhalter). 1973. Water quality survey of Burnt Bridge and Salmon Creeks, Clark County, Washington [memo; 2/1]. Olympia, WA: Washington State Dept. of Ecology.

Objective: To document existing water quality of both creeks prior to complete urbanization of drainage basins and to determine general location of water quality problem areas.

Summary: Salmon and Burnt Bridge Creeks were evaluated by sampling aquatic insects and measuring basic water quality parameters. The creeks were under the influence of light surface runoff even though the monthly rainfall was below average. The nutrients (NO₃-N, NO₂-N, and NH₃-N) at Burnt Bridge Creek are twice as high as Salmon Creek. Mill Creek (station BS) is the only station on Salmon Creek approaching the levels found in Burnt Bridge Creek. The two most downstream stations of Burnt Bridge Creek (28C070 and EB) exhibited the highest total coliform levels measured (20,000 and 8,000 colonies/100 ml). The source of these bacteria does not seem to be sewage due to low fecal levels and is probably due to surface runoff. Three stations on Salmon Creek (DS, BS, and AS) and two stations on Burnt Bridge Creek (28C070 and EB) were all higher than background turbidity levels by 50%. Soil erosion practices or other causative factors (construction) should be reviewd and modifed to prevent these increases. Burnt Bridge Creek has been nearly channelized and is mainly influenced by agriculture and urban runoff. Aquatic insect populations are depressed on this creek due to lack of suitable habitat. No further channelization of the stream above station BB should be allowed. Salmon Creek is a much more productive creek according to quantity of aquatic insects and fish habitat. Current operation of the four STP's should be maintained or upgraded to prevent damage to the resource. The source of the high nutrients and turbidity in Mill Creek (station BS) should be located and corrected. Salmon Creek even with the dicharges from four STP's exhibits lower levels of nutrients than Burnt Bridge Creek. The Columbia Acadamy STP should be repaired and the chlorine residual raised to and maintained at the required level. Operation of this plan by competent personnel should be required.
