Watery Rooster Tail Is A Sight To Behold

Off to the side of Highway 21 toward Idaho City is the spillway for Lucky Peak Dam, and it has been putting on a heck of a show lately.

According to the Army Corps of Engineers, who were on site, the Boise River is at flood stage when it hits 7,000 cfs, so the Lucky Peak Dam is doing its job and holding back the water. Currently, the intake of Lucky Peak Reservoir from Grimes Creek and Arrowrock Reservoir is a humbling 15,500 cfs.

With near-record snow packs, flood warnings have already been released. Here's hoping the rooster tail is enough to prevent any serious flooding this season.
