Little Thompson Reservoir in Weld County: How and When to Fish It

• Overview

  Set in Weld County, Colorado, this is Little Thompson Reservoir. Beyond the shoreline you have mixed woodland. With some 33 acres of water, there is room for a boat but no need of one. It lies lower than most water we list in Colorado. For a base, Johnstown sits 1.6 miles out. Milliken is 2 miles and Gilcrest 6.6 miles. The county line runs close by, so rules can change within a short drive.

• Where to Fish on Little Thompson Reservoir

  Depth is unmeasured here, so let the shoreline guide you. Look for where the old bank line still shows under the surface. Built water gives depth close in, which suits a bank angler. Public occurrence data for Weld County names white sucker, common carp, green sunfish, longnose sucker and bluegill. The county figures include rivers and lakes alike. Work Little Thompson Reservoir in sections rather than trying to cover it.

• Seasonal Patterns

  Long-term averages put July at about 72°F and January near 26°F. Most months fish reasonably, given the right weather. It is not guaranteed from one year to the next. Autumn steadies things again once the heat lets go. That shapes the year on Little Thompson Reservoir. Late summer often means an early start or nothing at all.

• Tackle & Baits

  Public sources are silent on who controls the bank. The nearest mapped parking is 0.9 miles away, so the last stretch is on foot. For the carp, bait a margin spot and sit on it; corn and bread still work. Where access is informal, keep it that way by behaving. Check whether bait restrictions apply before you buy any. Hartford Reservoir, 3 miles away, makes the obvious fallback. What applies at Little Thompson Reservoir may have changed since it was mapped.
