• Tackle & Baits

  The rules here are undocumented as far as public sources go. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. For the panfish, a small hook, a float and a piece of worm outfish everything fancy. Read any posted signs at the access point rather than assuming. Some ground is open by custom rather than by right, so tread carefully. Hart Lake, 0.4 miles away, makes the obvious fallback. For Armstrong Lake in particular, ask before you travel.
