Stag Island Habitat Rehabilitation and Enhancement Project

St. Louis District

Pool 25, Upper Mississippi River, Miles 247 - 250, Lincoln County, Missouri

Partners

  • Missouri Department of Conservation 

Description

The Stag Island HREP is located in Lincoln County, Missouri, near the downstream end of Pool 25, between river miles 247.7 and 249.5.  The project area consists of a complex of 4 islands and surrounding off-channel aquatic habitats located on the inside bend of the river, and total 486 acres. The four islands are mainly forested and lie low with respect to the river. 

Sedimentation has eliminated or significantly degraded productive off-channel habitats in Pool 25, especially backwaters, which serve as valuable spawning, rearing, and overwintering areas for riverine fish. Within the Stag Island complex, sediment plugs have formed in the opening of two sloughs. 

The objectives of this project are to decrease sedimentation in the side channel between Stag Island and the Missouri shore, restore high-quality winter habitat for fish, accumulate and maintain aquatic woody structure habitat, restore slackwater habitat for migratory wildlife, and improve the slough habitats on Stag Island.
