Northern Pike
Pike own the shallow marsh bays and the weed edges that run the length of the reservoir — the most-logged fish on Mountsberg, hunting a warmwater system that suits them exactly. This is vegetated, shallow, ambush water, and northerns spawn in the flooded weedy shallows the marsh provides. Start where the weed meets open water and work the bays; that seam is where they wait to collect whatever swims past.

The pike fishery tracks the weed and the water level. In spring, after the second-Saturday-of-May opener, fish are fresh off the flooded, weedy shallows where they spawn, and they hold the marsh bays and weed edges throughout the reservoir.
Come mid-summer the vegetation chokes the whole system — even an electric motor fouls in it — so the game narrows to the open weed pockets you can still reach by paddle. Fall reopens the water as the weed thins, and the bite picks back up along the edges.
Perch and the marsh's panfish forage feed them in the same cover they hunt. Two practical limits shape every trip: the winter drawdown that pulls the reservoir down, and the park's own rules — electric motors only, no gas, and a live-bait ban that leaves you worms and artificials.
Structure
The reservoir-wide vegetated shallows are classic pike ambush water and hold the lake's most-logged catch; the back bays warm first and fish early in the season.
As summer weed fills in, the fishable water shrinks to the open pockets and edges a paddler can reach — thick vegetation limits even trolling motors in places.
Regulations
This is a summary, not the legal regulation — confirm current rules with the official source before fishing.
