Rainfall runoff

Posted

In response to “Water Not Low Enough” which ran in the Aug. 17-23 issue of North Country This Week: The next time you take a glance at the Hannawa Dam please notice the gate built into the structure. This gate is called a floodgate. Between 4,000 to 5,000 cubic feet of water can be discharged per second thru this gate. It can be operated both remotely and/or locally. There is also another control gate on this site called a canal gate where water can be discharged at a rate of 500 cubic feet of water can be discharged per second. Having these two gates to use during a water crisis situation, there was no need to draw the Hannawa reservoir for a potential rainfall runoff.
