It sits well inside its county, with no border complications.

• Where to Fish on Threemile Lake

  There is no published depth for this one, so start shallow and work out. This is a lake, so the margins and the first drop matter most. A soft bed grows weed late into autumn, which keeps fish shallow. Reported across Matanuska-Susitna Borough: rainbow trout, Coho salmon, sockeye salmon, longnose sucker and Arctic charr. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Work Threemile Lake in sections rather than trying to cover it.

• Seasonal Patterns

  The warmest month averages 58°F, the coldest about 12°F. The year splits cleanly: hard water, then open water. Break-up comes around late April, and the run that follows is short and strong. The open-water window runs from around late April to about early November in an average year. Look to early summer and the first cool weeks of autumn. Anyone fishing Threemile Lake regularly works to that calendar.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. No dam controls it, and the level follows the season. Access points are not mapped for this water, which suits people who like quiet. For the trout, small spinners and a box of nymphs cover both approaches. Take the rules with you rather than trusting memory. Keep proof of licence with you rather than in the car. Brocker Lake sits 1.2 miles off and takes the overflow. None of that is settled for Threemile Lake in what we hold.
