The Center for Lakes and Reservoirs (CLR) at Portland State University (PSU) was established by the Oregon State legislature to address lake management and invasive aquatic species issues in Oregon. The CLR is in the Environmental Science and Management Department at PSU, which has a major focus on watershed and aquatic ecosystem management. Faculty from other PSU departments and other universities and adjunct faculty from federal agencies (US Fish and Wildlife Service, US Army Corps of Engineers, Smithsonian Institution) collaborate with CLR on research projects and serve on graduate student committees.

Lake and aquatic nuisance species management are the major foci of the CLR. We develop management plans and conduct research on limnological and invasive species biology in freshwater and marine systems. The Aquatic Bioinvasion Research and Policy Institute (ABRPI) is joint effort with the Smithsonian Environmental Research Center (SERC), which has facilities on the Chesapeake Bay and San Francisco Bay. The ABRPI strengthens our capabilities in marine research and broadens the geographic scope and habitat types where we work.

In 2001, the Governor's office charged the CLR with developing the Oregon Aquatic Nuisance Species Management Plan. The Plan is the cornerstone of our work on aquatic invasive species. It is a comprehensive approach to management of aquatic invasive species in the State and includes prevention, outreach and education, detection, research, and management planning components. The CLR is responsible for implementing the Plan in cooperation with state agencies with management responsibilities (Oregon Department of Agriculture, Oregon Department of Fish and Wildlife, Oregon State Marine Board).

NEW: Oregon Lake Watch Program

Come Join the Oregon Lake Watch Program! Are you interested in learning more about one of Oregon's great lakes? Do you go fishing, camping or boating and wonder what that plant is growing just under the surface or what our native crayfish look like? Volunteering with the Oregon Lake Watch (OLW) program may be for you! OLW is a new program starting up this spring with funding from the OSMB and organized by the Center for Lakes and Reservoirs at Portland State University. OLW is looking for people interested in protecting their favorite lake by learing to monitor water quality (things like water clarity and temperature profiles) and helping to find aquatic invasive animals and plants. Volunteers can pick any lake they're interested in within the state, so if you need an excuse to head up to the Cascades or out to the coast... this is it! Please visit our webpage for more details about the program.

Research Facilities

CLR Office BuildingFacilities available at the CLR include approximately 1300 square feet of office space in the Harrison Street Building for faculty, staff, and students; an 1800 square foot research greenhouse; and approximately 2000 square feet of analytical laboratories, equipment storage, and offices in PSU's Science Buildings I and II. The greenhouse contains 10, 1000-liter insulated tanks, with individual temperature and light control, for studying submersed aquatic plants. Shallow beds are also available for research on emergent/wetland species.
Laboratory equipment includes a Perkin-Elmer CHN analyzer, a Shimadzu TOC analyzer, Turner SCUFA for in-situ chlorophyll fluorescence, PAM and benchtop fluorometers, and spectrophotometers. Hydrolab and YSI equipment is available for field measurements of chemical and physical characteristics of lakes, along with bottom dredges, corers, plankton nets, etc. Biosonics hydroacoustic instruments coupled with Trimble GPS equipment are used for bathymetric mapping. Boats are available for work on most types of water (18-ft pontoon, 16-foot v-hull, 12-foot flat bottom, 16-ft kayak, and 10-foot inflatable). A light pick-up is used as a field vehicle.
