Holter and the Regulating Reservoirs are seeing fluctuating fish activity, including kokanee, walleye, and pike. Kokanee are deeper, while walleye thrive in weed beds using jigs and drop shots. For effective results, use chartreuse, pink, or orange lures. Early mornings and evenings offer the best chances for bites.

In Helena, summer fishing is thriving, particularly at Hauser Lake and the Regulating Reservoir. Walleye prefer weed pockets, with better evening bites using jigs. For trout, focus on the White Sandy stretch. Kokanee fishing is improving, with successful trolling techniques highlighted. Key colors for lures include pink, chartreuse, and metallics.

Walleye are found around weed beds, favoring subtle motions with lures like ned rigs and small paddle tails. The stretch from York Bridge to the dam is currently best for trout, with effective trolling using cranks and weighted cowbells at varying speeds. Kokanee are present but not abundant in Hauser.

Anglers are successfully catching kokanee in the Regulating Reservoir, especially during morning and evening hours. The preferred method involves trolling wedding rings with scented corn, using colors like chartreuse, pink, or orange. Fish are being found at depths ranging from 10 to 35 feet, with a speed of 1.0 to 1.2 mph recommended.
