Lake Onalaska is a 7,688 acre body of water created when Lock and Dam #7 inundated former backwater areas of the upper Mississippi River in 1937. The entire Lake is within the Upper Mississippi National Wildlife and Fish Refuge and all of the shorelands surrounding the Lake are owned by federal agencies (U.S. Fish and Wildlife Service and U.S. Army Corps of Engineers). The Lake Onalaska Protection and Rehabilitation District is an association of property owners whose land adjoins the federal shorelands, formed under Wisconsin Statutes, to play a role in the planning and management of the Lake's resources (more info.). Lake Onalaska has abundant fish resources, hosts large numbers of migrating waterfowl in spring and fall, and provides diverse human recreational interests.

New Aquatic Invasive Species Found on Lake Onalaska

Water lettuce and water hyacinth were found rapidly spreading near the Brice Prairie shore in early October after they were released from a garden pond. USFWS has issued a news release about water lettuce on Pool 7. The Lake District has played a very active role in removing these species. For more information and a chronology of events see our invasive species page.

U.S. Fish and Wildlife Service Saturday Programs

  • September 19: , 10:30 a.m. – 12:30 p.m.: Discovering Diving and Dabbling Ducks

    Soon we will say “hello again!” to many migrating waterfowl who use the Refuge as a stopover point on their long journeys. One way we can distinguish different types of ducks that visit the Refuge is by their feeding behaviors. Diving ducks prefer to dive under the water to look for food, whereas dabbling ducks prefer to sit on the surface of shallower waters. Come join a Ranger to learn more about diving and dabbling ducks, test your ID skills with our “ducks-on-a-stick” mounts, and go for a walk out to the Lake Onalaska Overlook in search of visiting waterfowl. We will walk a little over a mile. This program will end at the overlook and participants are invited to walk back to the Visitor Center at their own pace. This program is best suited for children ages 8 and above, but people of all ages are invited to participate. Please let us know by September 17 if you plan to join us.

Fred Funk Landing Plans

Semi-final versions of the plans for the upgrades at the Fred Funk Boat Landing on Brice Prairie were presented by MBA Architects in autumn 2014. These plans are being used for working through the permitting processes with various agencies:

COE Revised Land Use Allocation Plan

The U.S. Army Corps of Engineers has released a Land Use Allocation Plan (LUAP) document (link to pdf) which updates the original 1983 Master Plan with the intent of providing better information from modern aerial photos and Geographic Information Systems. The document states that "there are no new policy changes made or suggested in this document". The LUAP is used to guide federal agencies in determining what types of public uses should be allowed on federal lands along the upper Mississippi River.
