Fishing Rainbow Lake in Matanuska-Susitna Borough, Alaska

• Overview

  The Matanuska-Susitna Borough end of Alaska holds Rainbow Lake. Height above sea level is 197 feet. Surface area is around 159 acres, which gives you real water without needing a boat. The edge covers about 3.9 miles, enough to hold several distinct areas. For supplies, Willow is 4 miles out. It is 34 miles to Anchorage, the nearest city. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Rainbow Lake

  No depth figure appears in our records, so the bank has to tell you. Read the surface for the wind lane, then fish the edge of it. On a natural lake the weed line and the shelf beyond it do the work. Matanuska-Susitna Borough records list rainbow trout, Coho salmon, sockeye salmon, longnose sucker and Arctic charr among the fish reported. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Rainbow Lake repays a walk before the first cast.

• Seasonal Patterns

  The warm month here averages 59°F; the cold one sits at 7°F. Cold locks it up for a good stretch each year. Count on hard cover from midwinter, and open water from late April. Averages place the thaw at late April and the freeze at early November. The strongest runs come at either end of the open season. Anyone fishing Rainbow Lake regularly works to that calendar.

• Tackle & Baits

  Whether the bank is open is not something our records settle. This is a natural basin, not a dammed one. There is no mapped parking or launch nearby, which keeps numbers down. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Where access is informal, keep it that way by behaving. Barbless rules turn up on managed water more often than not. Crystal Lake, 0.9 miles away, makes the obvious fallback. Rules at Rainbow Lake are worth checking on the day.
