Irvine Lake Reports & Info I went out Sunday morning with the lil bro and did some shore fishing...didnt wanna spend the $50 on a boat when the lake closes at 4 pm. The water is dropping steadily and the bite has picked up some. We stayed until about 3pm and managed 2 cats. Missed quite a few bites and farmed one. ALOT more action than the previous 2 outings. I'll probably get out again this upcoming weekend and rent the boat.
