Peltier Lake and Centerville Lake are both located partially within the City and mostly in Lino Lakes. A private ditch flows northeasterly through the City to Clearwater Creek. Anoka County Ditch 55 flows from the City of Lino Lakes southwesterly through the City to Clearwater Creek. Judicial Ditch 3 flows into Clearwater Creek, which then flows west and then north through the City to Peltier Lake. The RCWD serves as the drainage authority for both of the public drainage systems (Judicial Ditch 3 and Anoka County Ditch 55), but not the natural waterways or private ditches. Judicial Ditch 3 ends approximately one mile upstream of Peltier Lake, where Clearwater Creek changes from an altered watercourse to a natural meandering channel. The extent of these watercourses is shown in Figures 10 and 11. Peltier Lake has a surface area of approximately 579 acres with a maximum depth of 18 feet. Water quality data has been recorded for some parameters since 1974. Centerville Lake is approximately 474 acres in surface area with a maximum depth of approximately 19 feet. Water quality data on Centerville Lake has been recorded since 1980. Centerville Lake has regional use for fishing and boating. As shown in Table 3.4, there are two Minnesota Department of Natural Resources (MnDNR) Protected Waters in the City. These include a portion of Centerville Lake, designated as 02000600, and a portion of Peltier Lake, designated as 02000400. Also included under MnDNR authority are three protected wetlands as discussed in the next section.
