7 Mile Creek Data Types: Excel file
Seven Mile Creek watershed, Nicollet County, MN | ||||||
Seven Mile Creek is a much-studied tributary of the Minnesota River. The watershed is small, just 24,000 acres (38 sq mi). It is dominated by row-crop agriculture, except in its lower reaches where the creek flows through a popular county park. Monitoring is focused on the creek's mainstem and its two largest tributaries, SMC 1 and SMC 2. | ||||||
