Reservoir D in Adams County: How and When to Fish It

• Overview

  Reservoir D lies in Adams County, in Colorado. Rolling hill runs right down to the water. This is a pocket water of some 12 acres, and every part of it is reachable from the bank. Derby sits 2.9 miles from here and is the nearest stop. Commerce City lies 4.5 miles off, Welby another 5.1 miles. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Reservoir D

  Depth is unknown to us, and the shoreline is the better guide. Standing timber shows when the level drops, and fish sit against it. Held water runs deepest at the wall and shallows back to the inflow. Records held for Adams County cover common carp, white sucker and bluegill. Take it as the county picture rather than a promise for this water. On Reservoir D that means starting tight and working out.

• Seasonal Patterns

  Seasonal averages run from 29°F in January up to 73°F in July. The year gives four workable seasons without severe ends. Cover comes and goes, so treat it with suspicion rather than trust. Autumn steadies things again once the heat lets go. At Reservoir D the season follows that pattern closely.

• Tackle & Baits

  Our records carry no access rule either way. Mapping is blank for access, so scout the approach before committing the car. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking is often the real limit rather than the bank itself. Where the way in crosses private ground, ask first. If the gate is shut, Lake Mary at 1.8 miles is the nearest alternative. Rules at Reservoir D are worth checking on the day.
