Surface water quality data exists for many of the water bodies within the watershed. Several agencies have instituted programs based on particular needs, including: • Anoka Conservation District (ACD) • Metropolitan Council • Minnesota Pollution Control Agency (MPCA) • U.S. Geological Survey (USGS) Monitoring parameters vary by monitoring program, but may include: • Water chemistry (e.g., phosphorus, total suspended solids, chloride) • Biological data (e.g., indices of biological integrity, macroinvertebrates, fish inventories) • Hydrologic data (e.g., flow, water level) Monitoring locations within the watershed are presented in Figure 2-10. Much of the historical monitoring data for the watershed is available from the MPCA's Environmental Data Access (EDA) database at: tt s:// ®•c.st t. n. s/} o-s rf, c t-r-t0 The Anoka Conservation District presently monitors water chemistry, biological, and physical parameters in several LRRWMO waterbodies (see Table 3-7). The ACD monitors the water quality of Round Lake and the Rum River annually, while Grass (Sunfish) Lake water quality is monitored every two years. The ACD also sponsors biomonitoring of invertebrates of the Rum River is done in the spring and fall of each year. The ACD also performs targeted monitoring studies to address specific water quality and quantity issues. Additional detail regarding the ACD monitoring programs, methods, and results are available from the ACD website at: tt, : s c r it i i-su• rt.
