White bass have been moving up Trinity River above Lake Livingston for some time, and also in the tributaries feeding lake Houston, East Fork of San Jacinto River. They always move up in Feb. and early March, but dont move back to the main lakes until May. I also questioned the timing, but, as stated, the males move up first. I never trust much fish talk that speaks in terms of Celsius, mm, and such, although I'm an engineer. ;\)
