During the spring season, anglers might encounter hatches of blue-winged olive, Callibaetis and pale morning dun mayflies, a variety of caddisflies, midges, damselflies and dragonflies. Freshwater shrimp (scuds) and leeches are present in weedy areas, too. Typically, midges are present in the morning and evening hours, followed by damselfly nymphs, dragonfly nymphs and a variety of caddis and mayfly nymphs. Spin- and bait-cast anglers also hook large trout in shallow areas on plugs, such as rainbow-colored Rapalas, copper and silver spoons and leadhead feather jigs. Those offerings are especially effective early and late in the day as trout move out of the depths and onto the flats.
