Boat Transfer Facility at Rapide Croche lock
The board of directors of the Fox River Navigational System Authority (FRNSA) is reviewing construction bids and revising conceptual designs for a proposed boat transfer facility at the Rapide Croche lock. Bids on the project came in higher than the $3.8 million budgeted, so the board voted to send the project back to committee for further study, development, and re-bidding.
The lock was sealed in 1988 and will remain closed as a barrier to prevent the spread of aquatic invasive species (AIS) through the Fox River and Lake Winnebago. Originally sealed to prevent sea lamprey from invading the waters, the barrier is effective in protecting the waters from other species.
The Fox River Navigational System Authority (FRNSA) is maintaining the barrier to be in compliance with Wisconsin Statute 237.10(2), the state law that created FRNSA. Additionally, the DNR rule NR 40 that makes it illegal to possess, transport, transfer, or introduce any invasive species in the state. However, we are also committed to restoring full navigation of the Fox River, so a boat transfer and cleaning station will allow recreational and commercial vessel access to Green Bay and Lake Winnebago via the Fox River.
Proposed plans call for modifying the existing lock to build and install a bridge crane and supporting structure complete with a hot water bath to destroy AIS. Detailed information about the proposed transfer station may be found at this link.
Monitoring the waterway
FRNSA has prepared an AIS Control and Monitoring Plan for the Rapide Croche Boat Transfer Station. The goal of this plan is to prevent the upstream spread of aquatic invasive species and safely transfer boats at the Rapide Croche Lock Barrier. When the station is operational it will incorporate the use of a Hazard Analysis and Critical Control Point (HACCP) plan that shall address the critical and operating parameters for station including documentation, record keeping and guidance for station operators.
The most updated, proposed design for the boat transfer and cleaning station is below.
