Haystack is currently at 75 percent full. Excess brood rainbow trout were released into Haystack Reservoir the third week of February. This is a rare opportunity for anglers to catch trophy-sized broodstock rainbow trout in Haystack Reservoir in late February and March. Anglers have been reporting success catching these large fish. Following draining of Haystack Reservoir for maintenance, anglers should expect slow fishing as the reservoir is restocked and fish populations rebound.
