I think much of the draw is the lahontan spawn brings the fish in shallower where the wade and “ladder” mostly fly anglers have better access to fish as they cruise in the shallower areas. The spawn period is considered to be December through May. There are winter and spring run spawning activity. The Feb through March is popular I think because weather is not as severe and the spawn activity starting allows easier access to the big fish especially for Anglers without boats. Fishing activity sure picks up in Feb and March. That’s my best guess.
time spent fishing isn't deducted from ones life
