• Where to Fish on Ash Tree Reservoir

  Depth went unrecorded, which puts the reading back on you. A reservoir gives you a hard edge, a shelf, and not much else. The old creek line under the surface is the feature worth finding. Records held for Harding County cover white sucker, stonecat, black bullhead and green sunfish. County data is a starting point rather than a guarantee. At Ash Tree Reservoir the water rewards a slow, careful approach.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No made access appears within a short radius, so plan to park on a verge and walk. A small crankbait along the drop and a worm in the thick stuff cover the bass. A phone call first saves an afternoon. Fishing rules and camping rules are set separately here. Failing this one, try Davis Draw Reservoir, 0.7 miles away. Confirm access to Ash Tree Reservoir locally before you travel.
