• Where to Fish on Black Hollow Reservoir

  The records we hold are silent on depth, so plan to find it yourself. The arms fish better than the open middle whenever the water is up. A reservoir gives you a hard edge, a shelf, and not much else. Across Weld County, recorded fish include white sucker, common carp and green sunfish. Those are county-wide records, so not every one of them will be in this water. On Black Hollow Reservoir that means starting tight and working out.

• Seasonal Patterns

  July runs about 71°F on average, January about 27°F. Temperature moves within a narrow band, and so does the fishing. Cover comes and goes, so treat it with suspicion rather than trust. June to September is hot work, so the first and last hours are what count. That shapes the year on Black Hollow Reservoir.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. We find no slipway, car park or made path within a short radius, so treat access as rough. For the carp, bait a margin spot and sit on it; corn and bread still work. Where the road in crosses private land, ask first. Some stretches are reserved and marked as such on the ground. If the gate is shut, Lillie Reservoir at 2.3 miles is the nearest alternative. What applies at Black Hollow Reservoir may have changed since it was mapped.
