Mason Reservoir in Weld County: How and When to Fish It

• Overview

  Mason Reservoir stands in Weld County, Colorado. It lies 4,849 feet above sea level. The water measures roughly 22 acres, so nothing here is far from anything else. Ground here is low by Colorado standards. Eaton is the closest place, 7.8 miles off. Ault is 9.6 miles and Kersey 9.9 miles. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Mason Reservoir

  No published figure covers depth, so learn it as you fish. The arms fish better than the open middle whenever the water is up. Rip-rap along the wall holds fish that the open bank never does. Across Weld County, recorded fish include white sucker, common carp, green sunfish, longnose sucker and bluegill. County data is a starting point rather than a guarantee. The shape of Mason Reservoir decides where the fish sit.

• Seasonal Patterns

  Between January at about 27°F and July at about 72°F, the water has a wide range to work through. Ice comes and goes from one year to the next. In a normal year the cover is thin and short-lived. The hot months push the fishing to dawn and dusk. That is the shape of the year on Mason Reservoir.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Nothing built is recorded close to the bank here. For the carp, bait a margin spot and sit on it; corn and bread still work. A phone call first saves an afternoon. Barbless rules turn up on managed water more often than not. For a change of water, Allison Reservoir is 1.9 miles distant.
