• Where to Fish on Eggleston Reservoir Number 4

  Nothing we hold settles how deep this runs. 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. Fish documented in Boulder County include black-spotted cutthroat trout, brook trout, brown trout, bluegill and rainbow trout. The county list is broader than any single water. The shape of this water rewards a slow walk along one bank.

• Seasonal Patterns

  In an average year July sits at 71°F and January at 31°F. Spring and autumn are the strongest, but nothing is truly closed. Hard water here is never dependable, so check for yourself before stepping out. Autumn steadies things again once the heat lets go. On this water the same rules apply, with local timing.

• Tackle & Baits

  The paperwork position is blank for this one. Parking is not close: half a mile from the bank, and no nearer option is mapped. For the trout, small spinners and a box of nymphs cover both approaches. Bank access can be seasonal on ground like this. Access can change hands, so last year's answer may not hold. Should this one be busy, Marshall Lake is 0.9 miles off. Where this water is concerned, a local answer beats a written one.
