Fishing at Round Lake, Boulder County, Colorado

• Overview

  Within Boulder County, Colorado, you have Round Lake. The water sits 11,175 feet up. About 3 acres of surface, which puts the far bank inside easy sight. It is a small entry by Boulder County standards. The nearest town is Granby, 14 miles away. Then Fraser, 16 miles, and Nederland, 16 miles. The nearest boundary is a fair way off.

• Where to Fish on Round Lake

  No depth figure has reached our records, which makes a plummet useful. A soft bed grows weed late into autumn, which keeps fish shallow. Where the bottom changes texture, fish gather; find that line. Across Boulder County, recorded fish include black-spotted cutthroat trout, brook trout and brown trout. Those are county-wide records, so not every one of them will be in this water. Round Lake fishes better once you know its edges.

• Seasonal Patterns

  July runs about 53°F on average, January about 17°F. Winter closes the water for a while, and the reopening is worth catching. Ice fishing carries the winter, and the water opens about mid May. The season between ice runs from about mid May to early November. The weeks after the thaw and the ones before the freeze are the strongest. The season on Round Lake follows the weather closely.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. Public data shows nothing built here, so treat the whole approach as informal. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Ask in the nearest town if you are unsure. Where the way in crosses private ground, ask first. Stone Lake at 0.7 miles is the sensible second choice. The position on Round Lake is worth confirming on the day.
