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.
