My buddies have been hitting it now & again here lately. Fishing at night - spider rigging minnows/jigs/both - catching limits - catching a few quality sized fish, too. Some have been fishing the habitat put out by the KDFWR & some have been simply following the river channel edges. Most times the fish were between the 12-20ft depths.

Last COE temp chart was 9/10/19 ... showing water temps steady down to 20ft @ ~79deg & O2 levels good to around 20ft (NOTE: these values were taken at the dam & are 10days old)

As far as May ... depending on the Winter & Spring rains, you can find yourself fishing for pre-spawn, spawn, or post spawn fish well into the month. NOTE: Last year the lake was flooded from Feb to May.
