Fish species in Boulder Reservoir

Boulder Reservoir is a reservoir in Boulder County, Colorado, and covers about 700 acres, reaches about 28 feet at its deepest point and holds roughly 13,270 acre-feet.

The best plan at Boulder Reservoir is to choose one arm or shoreline and work it from shallow cover to the first deep break.

What Makes Boulder Reservoir Different

Boulder Reservoir is shallow for its size and exposed to Front Range wind. A light push can move bait toward a bank, while a hard blow can muddy broad flats and make the clean-water edge more useful.

Walleye and smallmouth bass fit firm points and rock. Perch, crappie, and bluegill use the best weeds or protected pockets. Trout may roam open water, so troll a small spoon when the bank pattern is quiet.

Boulder Reservoir FAQs

Why does wind matter at Boulder Reservoir?

The open, shallow water reacts quickly, moving bait on a light wind and muddying broad flats during a stronger blow.

Where should Boulder Reservoir walleye anglers begin?

Work a firm point or rocky edge with a jig or crankbait, then check the first drop.

What is a useful panfish plan at Boulder Reservoir?

Use a small jig or worm around the cleanest weeds and protected pockets.
