Prospect Reservoir Fishing Guide, Weld County, Colorado

• Overview

  Prospect Reservoir sits in Weld County, out in Colorado. Beyond the shoreline you have farm and woodlot. It measures some 379 acres, and wind has room to build across it. You are looking at roughly 4.1 miles of shoreline, with plenty of water between access points. Size puts it in the front rank of our Weld County list. Nearest place of any size is Keenesburg, 6.5 miles away. Further out sit Hudson (7.9 miles) and Lochbuie (11 miles). No boundary runs near, so the county rules hold throughout.

• Where to Fish on Prospect Reservoir

  No figure exists for depth, so let the water show you. Levels move with the draw rather than the rain on water like this. Look for where the old bank line still shows under the surface. Species logged across Weld County include white sucker, common carp, green sunfish, longnose sucker and bluegill. Records at this level tell you what is in the area. Take Prospect Reservoir a stretch at a time.

• Seasonal Patterns

  Average temperature peaks around 73°F in July and bottoms out near 28°F in January. The freeze here is occasional rather than annual. Cover comes and goes, so treat it with suspicion rather than trust. April and May are the settled weeks, with October close behind. Anyone fishing Prospect Reservoir regularly works to that calendar.

• Tackle & Baits

  Our records carry no access rule either way. Access points are not mapped for this water, which suits people who like quiet. For the carp, bait a margin spot and sit on it; corn and bread still work. Rules differ from one water to the next round here. Night access is frequently treated as a separate matter. Failing this one, try Horse Creek Reservoir, 3.7 miles away. None of that is settled for Prospect Reservoir in what we hold.
