IDNR Announces Updated Operating Schedule at Stratton-Bolger Lock and Dam
MCHENRY, Ill. – The Illinois Department of Natural Resources (IDNR) today announced an updated operating schedule for the William G. Stratton-Thomas A. Bolger Lock and Dam facility on the Fox River in McHenry County for the 2019 navigation season.
To facilitate ongoing construction operations at the Stratton-Bolger facility, beginning Aug. 19, the lock will be closed on Mondays and Tuesdays (with the exception of Labor Day Monday, Sept. 2 and Columbus Day Monday, Oct. 14) through the end of the 2019 navigational season.
Beginning Aug. 19 and continuing through the month of September, IDNR lock tenders will operate the lock on Wednesdays through Sundays from 8:00 a.m. until midnight.
For the month of October, IDNR lock tenders will operate the lock on Wednesdays through Sundays from 8:00 a.m. until 8:00 p.m.
The Stratton-Bolger facility is closed for the winter season each year from Nov. 1 through April 30.
So you could really do a 24/7 full out construction push the month of April and probably at least half of November and knock it out rather than the middle of boating season like you tried to pull in July this year.
Closing the river after NO rain right after July 4th takes brains.
The riverfront owners who happened to take that week off for staycation got RIPPED OFF!
