Campbell Lake 04-0196-00 Lake Water Quality

Campbell Lake is located 8 miles north of Bemidji, MN in Beltrami County. It is an irregular shaped lake covering 462 acres (Table 1). Campbell Lake has one inlet and one outlet, which classify it as a drainage lake (Figure 1). The inlet is located on the southern end of the lake and receives drainage from Peterson Lake. The northern bay contains the outlet. Water from Campbell Lake joins the Turtle River and flows into multiple lakes from there. Water quality data have been collected on Campbell Lake in since 2001 (Tables 2-3). These data show that the lake is at the mesotrophic/eutrophic border (TSI 49-51), which is characteristic of dense aquatic plant growth and possible algae blooms in late summer. Campbell Lake is a member of the Turtle River Watershed Association. The Turtle River Watershed Association was started in 1998, and includes representatives from eleven different lakes. Each lake has at least one member on the board of 19. With a membership of almost three hundred, the Turtle River Watershed Association has worked extensively towards maintaining and improving water quality throughout the watershed. They have been involved in many projects, including water quality monitoring, plant surveys, ditch cleanups, and newsletter distribution.
