Red Rock Lake Fishing Guide, Boulder County, Colorado

• Overview

  Red Rock Lake is one of the Boulder County waters in Colorado. The country round it is rolling bush from end to end. This is a pocket water of some 5 acres, and every part of it is reachable from the bank. Most waters listed here for Boulder County are larger. Start from Nederland, 8.5 miles down the road. Boulder is the closest city, 15 miles away. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Red Rock Lake

  Depth is not on record here, which means reading the ground instead. A natural lake fishes on cover, and cover here means weed and timber. Still water like this holds fish on the edges rather than out in the open. Fish documented in Boulder County include black-spotted cutthroat trout, brook trout, brown trout and bluegill. County records show the wider picture rather than this one place. The shape of Red Rock Lake rewards a slow walk along one bank.

• Seasonal Patterns

  On the long-term average, July reads 55°F and February reads 22°F. The freeze arrives properly here and holds. Break-up comes around mid May, and the run that follows is short and strong. The water is typically free of ice between mid May and mid November. Late spring and early autumn carry the year between them. Red Rock Lake fishes to that pattern most years.

• Tackle & Baits

  Nothing in our records says who may fish here. There is somewhere to leave the car, 140 yards off. A toilet block sits half a mile away. Light line and small metal for the trout; a fly rod earns its place on calm evenings. A landowner's word beats anything printed elsewhere. Rules for boats are stricter than rules for the bank in many places. Left Hand Reservoir, 1.5 miles away, makes the obvious fallback. Check the position at Red Rock Lake before loading the car.
