With the start of the summer boating season, Memorial Day weekend, extended hours at Tenney Lock on Lake Mendota will be offered from May 22nd through May 25th. The Tenney Lock provides navigation between Lakes Mendota and Monona on the Yahara River Chain of Lakes. The remaining two locks at Babcock on Lake Waubesa and LaFollette on Lake Kegonsa remain closed to navigation. To assist boaters with navigation within the Yahara River Chain of Lakes, buoys are now in place marking slow no wake zones, channel markers, rock hazards, and swim areas.

Dane County is also reminding boaters to help protect waters from aquatic invasive species. Before entering and after leaving a water access, boaters are reminded to:
o Inspect and remove aquatic plants, animals, or mud from boats, trailers, and equipment.
o Drain all water from a boat’s bilge or livewell by removing drain plugs.

Extended hours for Tenney Lock are as follows:

Friday May 22nd
11 a.m. – 10 p.m.

Saturday May 23rd
9 a.m. – 10 p.m.

Sunday May 24th
