flows from the upland agricultural area into Seven Mile Creek Park. The
park is located four miles south of St. Peter and seven miles north of
Mankato along US 169. It is one the area's finest parks and is managed
by Nicollet County. Over eight miles of multi-use trails wind through
a beautiful, deep forested valley with a spring-fed trout stream flowing
down the middle. You can hike, bike, and ride horses on the trails (Park

Seven Mile Creek is a designated trout stream. This type of fishery is very rare for South Central Minnesota. These springs are key for trout survival. A trout stream requires a certain mix of streambed geology, adequate groundwater, and compatible land use within the watershed in order for sensitive fish like trout to survive. One of the most important factors is temperature. Trout need cold water and cannot tolerate temperatures above 75 degrees. In an area where prairie and now cropland dominate, cool temperatures are not typical. Seven Mile Creek is an exception. Because this area contains steep gradients, heavily forested vegetation, and a gravelly substrate, a very unique habitat and fishery can exist. A streambank protection project was completed to protect the streambank from erosion as well as to increase trout habitat.
the Department of Natural Resources stocks Seven Mile Creek with fingerling
brown trout (less than a year old, about 4 inches long). The stocked trout
have grown up to 18 inches long, although most are around 6 to 12 inches.
The trout can usually be seen in the deep pools when the water is clear.
Quietly approach the stream and hide behind vegetation to observe and
maybe catch these wary fish. (More trout information)
