Temporary Drawdown of the Rock River to Repair Centerway Dam Beginning September 20

.From the City of Janesville -


The Rock River water level above the Centerway Dam in Janesville will be lowered in order to repair or replace several missing flashboards that were damaged during the flood of 2008. North American Hydro applied for the temporary drawdown of the Rock River between the Indianford Dam and Centerway Dam in order to replace the boards in the structure. The drawdown will begin Sunday, September 20 and is expected to take 6-7 days. The reservoir will be lowered no more that 6 inches a day until a drawdown of about 3 and a half feet has been reached. The river will be at its low point for approximately 4-5 working days to make repairs to the Centerway Dam.

All areas immediately upstream of the Janesville Centerway Dam, some further upstream and possibly some downstream will be affected by the drawdown. The Rock River will remain drawn down until October 6. If you have any questions related to the river drawdown,

City Boat Launches to Close Next Week due to the Rock River Drawdown

In conjunction with the Rock River drawdown, the City will close all boat launches once the river reaches a low enough level to be deemed unsafe. Those who have boats on the river may want to put their boat on its lift or bring it ashore in the coming days. Those who need to bring their boats ashore using the boat launches should do so by next week to ensure the boat launches will be open. More information on exact closure dates will be provided in the near future. For questions concerning the Janesville boat launch operations in the coming weeks,

contact Tom Presny of The Janesville Parks Division at 755-3026.
