The Vancouver Lake warmwater fish population was sampled during the fall of 1998. Vancouver Lake is a large lake, connected directly to the Columbia River through the Lake River to the north and the constructed flushing channel on the eastern shore. A total of 16 species of fish were encountered, mostly warmwater game fish with a few seasonal visitors. The lake has suffered from water quality problems, and during the 1970s, it was dredged, and a channel was created to aid in increasing the water turnover rate, effectively connecting both ends of the lake to the Columbia River. As there is direct access to the Columbia River, managing this lake as a closed system may prove difficult. It is of our opinion that it may be a more effective use of resources to increase the anglers access to the available resources through providing improved boat launch access, and fish habitat structure throughout the lake. Additionally, educating the public about the how-to's of common carp angling could possibly open up additional resources not commonly utilized by the public. (Document pdf contains 38 pages)

This thesis is concerned with the beneficiation of an oxidized lead ore. Emphasis was placed upon concentration by flotation rather than by gravity methods, although some investigation was made with the Wilfley shaking table. The concentration of lead minerals received most consideration in the problem, but wherever possible attempts were made to increase the silver and gold concentration along with the lead.
