I'm kind of with you on this. The big reason the NWS alerts don't work is because we've become fatigued by all the Amber Alerts, storm watches and whatnot that buzz our phones throughout the day and night. There needs to be some discretion as to how these are issued, and I would hope the sirens would be exercised with extreme caution. They ABSOLUTELY should be developed and configured with input from the camps, RV parks and condos along the river. Give a XX minute alarm when upstream thresholds are met (rising waters, X feet above normal pool, etc), and have an understood evacuation protocol in place. Each camp, for instance, should have a procedure in place verified by the county for when the alarms go off, each RV camp and River Inn have their own protocols (evacuate, drive downstream to Rendezvous point X), etc. And again, they need to ensure they guard the sirens to where they don't become the next overused NWS alerts that get ignored.
