Description, Use and Regulations

Description:  The Fawn Island (Little Sioux) site is located along the left descending bank of the Missouri River. 

  • The project contract was awarded in May 2009 and was completed in the spring of 2010.  The completed project consisted of a 2,975-foot-long by 150-foot-wide chute  of approximately 9 acres of shallow water habitat. 
  • However, because of erosion from 2011 flooding, the upper end of the chute was temporarily closed, making this site a backwater that is connected at the lower end during normal flow levels.
  • This project incorporated new development ideas and construction methodologies to add large woody debris structures in the chute throughout its length.  These structures will be monitored to assess their performance from many aspects including biological response and longevity. 

Status:  Open to the public.  Construction is complete.

Site Use:  The site is open to the public for a variety of outdoor activities including fishing, bird watching, and hunting when in season.

Site-use Regulations:  

  • People visiting these areas must comply with all applicable federal and state laws and regulations, including hunting, fishing, etc.  In general Title 36 Part 327 of the Code of Federal Regulations governs the use of Corps property.  Other regulations may apply to properties owned by other federal agencies.
  • Special regulations and restrictions may be posted on site.

Special-use Regulations:  See above.
