Dr. Weitkamp has been investigating fisheries and associated water qualib' issues in the Pacific Northwest River system since 1971. His initial research in this area dealt with the _ater qualir), issue of supersaturation through out the Columbia and Snake Rivers. He subsequenti.v _vorked _vith various habitat, rearing and passage issues in rivers and estuaries of the Pacific Northwest. This _ork investigated the effects of various habitat and water quali_" alterations on fisheries resource. He has designed, managed and directed research investimmng aquatic populations and habitat. Don Weitkamp, Ph.D., is a Parametrix Principal responsible for projects dealing with salmon habitat issues in both estuarine and freshwater. He has conducted numerous salmon habitat projects in the streams and estuaries of the Nor_west to analyze the habitat the' use in port areas. These investigations have determined how young salmon behave in the habitats provided by altered shorelines such as piers, as well as along more natural shorelines. During the last two years Dr. Weidcamp has been conducting an intmasive review of the liter___mredealing w_ the esmarine rearing requirements of young chinook and other salmon resulting in an extensive annotautd bibliography and draft literature review. ANALYSIS OF POTENTIAL RESTORATION lV[EASIJR_S In the 1970' s Dr. Weitkamp began assessing habitat restoration potential for chinook spawning and rearing in both freshwater and estuarine environments. He developed the design and guided monitoring of intertidal rearing habitat in Commencement Bay in 1988 after assessing potential restoration measures for a contaminated sediment site (Tacoma Kraft Mill). Recently he analyzed…
