Andalusia Small Boat Harbor


Mississippi and Illinois Rivers


All small boat harbor projects have a local sponsor, usually a municipality. Assurances between the Corps and local sponsor provide for the Corps to maintain adequate access ways, while the local sponsor provides adequate areas and retaining structures for dredged material placement. Maintenance dredging of small boat harbors is usually accomplished by the local sponsor through a contract. USACE staff periodically provide technical support to local sponsors to assist them in developing their dredging contracts. Harbors have historically been dredged every two to five years if funding is available. Based on project priority and the last funding received, the following harbors were dredged in FY10:

  • Andalusia Harbor located at river mile 473, Rock Island County, Illinois. Sponsor - Village of Andalusia.
  • Moline Harbor located at river mile 488 in Rock Island County, Illinois. Sponsor - City of Moline.
  • Quincy Bay and Quincy Harbor located at river mile 327.4 in Adams County, Illinois. Sponsor - City of Quincy.


The River and Harbor Act of 1962 authorized the modification of the Mississippi River 9-foot Navigation Project, between the mouth of the Missouri River and Minneapolis, to provide for the construction and maintenance of 14 small boat harbors and for the maintenance of one existing small boat harbor (Quincy Bay). Two are on the Illinois Waterway and eleven are on the Mississippi River. The projects were constructed for shallow draft recreational vessels, and projects depths range from five feet to nine feet at flat pool.


The 2010 Energy and Water Development and Related Agencies' Appropriations Act, Conference Report 111-278, appropriated funds in the amount of $900,000 for dredging Western Small Boat Harbors. Since 2010, no additional funding has been appropriated for dredging small boat harbors in Rock Island District.
