Gates on the RC Spillway haven't been open in 5 or 6 years and when they are only TRWD personnel or their friends have access. Your info is probably pertaining to the "Waterfall" which is water pumped into RC from the Wetlands Project from across Hwy 287. Many folks fish it in the Spring and cooler months as it attracts baitfish and fish. Not much use in fishing it in the warmer months as the fish are scattered all over the Main Lake now that they have spawned.
Good fishing on RC the past few weeks!
