Althea Lake in Middlesex County: How and When to Fish It

• Overview

  Althea Lake is one of the Middlesex County listings for Massachusetts. It sits in rolling bush country. Roughly 42 acres: a morning covers one end, an afternoon the other. A shoreline of some 1.0 miles keeps the choices simple. Nearest town is Tyngsboro, 2.3 miles off. Lowell is the closest city, 4.3 miles away. Being near a boundary, it pays to know which side you are fishing.

• Where to Fish on Althea Lake

  Depth is unmeasured here, so let the shoreline guide you. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Fish documented in Middlesex County include bluegill, pumpkinseed, chain pickerel and yellow perch. Records at county level tell you what is around, not what is stocked here. On Althea Lake a short move beats a long cast.

• Seasonal Patterns

  Seasonal averages run from 23°F in January up to 71°F in July. Cold winters and warm summers give a wide working range. Hard water holds through the cold months, breaking up near late March. Ice clears near late March and comes back about late December in a typical year. Just after the ice goes and just before it returns, the fishing lifts. That shapes the year on Althea Lake.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. This is a natural basin, not a dammed one. Lake Mascuppic Access sits about half a mile away and carries the launch. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. Parking space is the usual limit rather than the bank itself. Rules for boats are stricter than rules for the bank in many places. For a change of water, Long Pond is 1.9 miles distant. Ask locally about Althea Lake if anything is unclear.
