Chestnut Reservoir, Colorado: Fishing Spots and Seasons

• Overview

  Weld County, Colorado, is where Chestnut Reservoir sits. It lies 4,797 feet above sea level. It covers about 3 acres, so this is small water you can walk round in under an hour. It is a small entry by Weld County standards. For a base, La Salle sits 4.1 miles out. It is 8.7 miles to Greeley, the nearest city. The nearest boundary is a fair way off.

• Where to Fish on Chestnut Reservoir

  Without a survey to go on, judge depth from how the bank falls away. Held water runs deepest at the wall and shallows back to the inflow. Inflow corners move water, and moving water gathers fish. Across Weld County, recorded fish include white sucker, common carp, green sunfish, longnose sucker and bluegill. Those are county-wide records, so not every one of them will be in this water. The shape of Chestnut Reservoir rewards a slow walk along one bank.

• Seasonal Patterns

  Long-run averages give July about 72°F and January about 26°F. Most months fish reasonably, given the right weather. It is not guaranteed from one year to the next. The hot months push the fishing to dawn and dusk. Expect Chestnut Reservoir to follow that timing. Spring warms the shallows first, so start there.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. The map shows no ramp or car park nearby, so this is a walk-in water. For the carp, bait a margin spot and sit on it; corn and bread still work. Gates get locked out of season on water like this. Night access is frequently treated as a separate matter. Failing this one, try Behrens Reservoir, 1.9 miles away. Confirm access to Chestnut Reservoir locally before you travel.
