Jewel Lake in Boulder County: How and When to Fish It

• Overview

  Jewel Lake stands in Boulder County, Colorado. It lies 9,970 feet above sea level. It covers about 3 acres, so this is small water you can walk round in under an hour.

The boundary is near enough that local access rules are worth double-checking.

• Where to Fish on Jewel Lake

  Depth went unrecorded, which puts the reading back on you. Where the bottom changes texture, fish gather; find that line. Read the surface for the wind lane, then fish the edge of it. Boulder County records list black-spotted cutthroat trout, brook trout, brown trout and bluegill among the fish reported. Species recorded across the county may be limited to a few waters. Take Jewel Lake a stretch at a time.

• Seasonal Patterns

  Average temperature peaks around 52°F in July and bottoms out near 19°F in February. Expect a real winter and a strong spring after it. The lid arrives early and lasts until roughly late May. Averages place the thaw at late May and the freeze at early November. From the thaw to midsummer the fishing improves week by week. That is the shape of the year on Jewel Lake.

• Tackle & Baits

  Our records carry no access rule either way. Mapping shows a campsite some half a mile from the water. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Season dates differ by species, so read the table. Where the way in crosses private ground, ask first. Mills Lake sits 0.2 miles off and takes the overflow.
