Cold Springs Habitat Rehabilitation and Enhancement Project

St. Paul District

Pool 9, Upper Mississippi River, Miles 653 - 654, Crawford County, Wisconsin, Congressional District: WI - 3

Partners

  • USFWS  

Description

The primary habitat deficiencies were low dissolved oxygen levels in winter, forcing fish to migrate from the backwater area.  Sedimentation had also decreased deepwater habitat, preventing fish from escaping the area.


Quick Facts

  • Approximate Acres: 30
  • State(s) Covered: WI
  • Land Ownership: USFWS
  • Management Agency: USFWS
  • Management Authority: Refuge

Features

  • Construction of a weir (a small dam with a controlled opening) across Kettle Creek where it enters the backwater.  This stoplog structure permits creek water to be diverted into the south lobe during the winter
  • Dredge a 4-foot-deep channel through a shallow area in the north lobe to permit fish access to areas with adequate dissolved oxygen levels
