Good morning Ben,
Rest easy, even the heavier crews that over eat at the He Man will have plenty of water. We are a flood control reservoir, not a water source, so we mostly experience a reduced flow as opposed to a reduced summer pool level as the Army Corps likes to call it. The technology to make Chuck Mill waters potable can be, shall we say, rather dicey, so the fellow that made the call to utilize the lake for flood control only was using good judgment for a change, or possible listened to the Native Americans for once, being familiar with the river for say 10,000 years prior as they were.
Just add a good sailing breeze and we will be set. See you soon, Marion
