Fishing Recommendations

Welcome to one of the gems of the Maine North Woods. Spencer Lake, located in the Jackman region (T3 R5 BKP WKR), is a quintessential North Woods fishery. Surrounded by rugged mountains and dense timber, it offers a wilderness experience with a chance at some truly impressive native fish.

As your guide, here is the lowdown on how to tackle Spencer Lake for Brook Trout and Landlocked Salmon.


🎣 Location Overview

Spencer Lake is a deep, cold-water lake approximately 6 miles long, covering over 3,000 acres. What makes it special is its depth and water quality. Unlike many shallower Maine ponds that warm up too much in the summer, Spencer has deep "refugia" (colder layers) that allow Brook Trout to grow to trophy sizes—often exceeding 3 or 4 pounds.

The lake is framed by the dramatic Little and Big Spencer Mountains. The shoreline is rocky with significant drop-offs, but it also features several key inlets and a major outlet (Spencer Stream) that are magnets for fish. Anglers love it because it offers a "big water" feel with "remote pond" tranquility.

💡 Pro Tips & Local Knowledge

  1. Find the "Cool" Water: In the summer, look for the mouth of Fish Brook or other small unnamed trickles. The water entering the lake is often 5-10 degrees cooler, and Brookies will stack up there like cordwood.
  2. The "Spencer Twitch": When trolling streamers, don't just let the rod sit. Use your hand to give the line short, erratic jerks. This often triggers a Salmon that has been following the fly for minutes.
  3. Wind is your Friend: A "Chop" on the water breaks up the light and makes the fish less spooky. If the lake is glass-calm, go deep or stay very quiet.
  4. The Outlet: The area near the dam/outlet where the water begins to move toward Spencer Stream is a prime spot for Landlocked Salmon, especially in the evening.
