• Where to Fish on Wonderland Lake

  Depth remains unrecorded, so treat the first session as a survey. Held water runs deepest at the wall and shallows back to the inflow. Standing timber shows when the level drops, and fish sit against it. Survey and observation records for Boulder County include black-spotted cutthroat trout, brook trout, brown trout, bluegill and rainbow trout. Records at this level tell you what is in the area. Wonderland Lake gives up its fish to patience rather than distance.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. The nearest car park is half a mile from the water. There are picnic tables half a mile away. Toilets show in mapping about half a mile away. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Local rules can differ across the county line, so check where you stand. Some water is controlled locally without a sign saying so. Maxwell Reservoir, 0.6 miles away, makes the obvious fallback. Confirm access to Wonderland Lake locally before you travel.
