Last Friday me and a friend fished the tailwater below Cordell Hull in his boat. We put between 15-20 rockfish in the boat and kept one for eating purposes. They were all small (3-7 lbs) but were a ton of fun to catch. Was thinking about going back on Friday if I didn't hunt but heard the tailwater was closed up by the dam. Didn't believe it so I called the resources office at Cordell Hull and sure enough, the tailwater is closed to all boat traffic from the right side ramp up to the dam. They are blasting on the cliffs there and this is apparently the reason. The lady I spoke to said they were meeting about the closure today but didn't know how long it would be effective.
Good rule of thumb is to never wrestle with a pig. You'll only end up getting dirty and the pig likes it!
