Fishing at Jenny Lake, Grand County, Colorado

• Overview

  Jenny Lake is one of the Grand County waters in Colorado. The setting is mixed forest on every side. About 3 acres of surface, which puts the far bank inside easy sight. Our Grand County list holds plenty of bigger water. For a base, Fraser sits 8.2 miles out. The nearest city of size is Boulder, 22 miles away. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Jenny Lake

  Our records hold no depth for this water. The productive water is a rod length or two out, not a hundred. Read the surface for the wind lane, then fish the edge of it. Grand County records list black-spotted cutthroat trout, brook trout and rainbow trout among the fish reported. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Anyone new to Jenny Lake should walk it once before setting up.

• Seasonal Patterns

  Expect July to average close to 54°F, with January the cold end at about 20°F. A solid cap is the normal state through winter. Ice-out usually falls in mid May, and the weeks after it fish hardest. Break-up near mid May, freeze-up near mid November: that is the shape of an average year. Look to early summer and the first cool weeks of autumn. Keep it in mind when planning a trip to Jenny Lake.

• Tackle & Baits

  Our records carry no access rule either way. 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. Season dates differ by species, so read the table. Access can change hands, so last year's answer may not hold. Yankee Doodle Lake, 0.6 miles away, makes the obvious fallback. Nothing on Jenny Lake should be assumed from this page alone.
