Seriously, why not? Because its Gold Medal water? So are North Delenay and Steamboat Res. You can even use bait at Steamboat. Because the water level drops in the winter? They take water out of Blue Mesa, Turquiose, Twin Lakes, Rudei, and Williams fork in the winter. Slot limits for the fish? Got those at Twin Lakes,Crawford, and the Delenays. Does anyone really have a good reason or is it because Aurora Water says so??? ???
