SECTION 2 2.7. Public Utilities Elk River is located outside of the Metropolitan Urban Service Area. Both sanitary sewer and subsurface sewage treatment systems are located within the City.Elk River has 8 municipal wells for water supply and distribution as well as numerous individual wells throughout the City. Storm sewers,ditches,curbs,and gutters provide stormwater conveyance for the City. Figure 2 shows the City's stormwater system of pipes,channels, and ponds.Future street maintenance and redevelopment will likely dictate the extension or reconstruction of the storm drainage system. 2.8. Surface Waters Many of Elk River's lakes, streams,and wetlands are protected under the Department of Natural Resources' protected waters program. Refer to Figure 3 in Appendix A for a map of the Public Waters Inventory (MN DNR) and National Wetland Inventory(US Fish and Wildlife). The Department of Natural Resources is the regulatory agency that permits work in public waters. In addition,the Army Corps of Engineers has permitting authority over waters of the United States, which often includes individual lakes, streams, and wetlands. Local Government Units(LGUs)are responsible for administering the rules of the Wetland Conservation Act of 1991 (WCA). The intent of the WCA is to promote no net loss of wetlands. Elk River is the LGU responsible for administering the WCA within the City. 2.8.1. Water Quality Data Water quality data for the City has been obtained from the Minnesota Pollution Control Agency (MPCA)Environmental Data Access site. This database is utilized by participating agencies to compile water quality testing data and is almost entirely used for the storage of water quality parameters. Refer to Figure 7 for many of the water quality monitoring locations within the City of Elk River. Water quality monitoring information/data can be found at the MPCA's Environmental Data Access site at hltp://www.pca.state.mn.us/index.php/water/water-monitoring-and-reporting/water-moni toring-and-reporting.html. 2.8.2.
