Marfell Lake Number 1 is a Boulder County water, Colorado side. Beyond the shoreline you have mixed woodland. Nearest town is Lafayette, 1.8 miles off. Boulder sits 9.9 miles out, and it is the nearest city worth the name. If this one is busy: Prince Reservoir Number 2 out at 0.7 miles, Erie Lake about 1 mile, Thomas Reservoir out at 1.1 miles, Waneka Reservoir about 2.4 miles and Hecla Lake out at 2.9 miles. A county boundary sits nearby, which can matter for local access rules.
Our records hold no depth for this water. Points where the flooded channel swings in are the reliable ones. Inflow corners move water, and moving water gathers fish. Open biodiversity records for Boulder County list black-spotted cutthroat trout, brook trout, brown trout and bluegill. What holds for the county may not hold for this water. The shape of this water rewards a slow walk along one bank.
Long-run averages give July about 73°F and January about 28°F. The year turns gently, without extremes at either end. Hard water here is never dependable, so check for yourself before stepping out. The cooler months are the comfortable ones to fish here. Plan around that when you fish this water.
The access position is unclear from public sources. Recorded parking is half a mile off, far enough to travel light. The water borders Josephine Roche Open Space, so reserve rules are likely to apply. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Parking space is the usual limit rather than the bank itself. Some ground is open by custom rather than by right, so tread carefully. Prince Reservoir Number 2, 0.7 miles away, makes the obvious fallback. Ask locally about this water if anything is unclear.
