• Tackle & Baits

  The paperwork position is blank for this one. Anglers are recorded at Cold Spring Pond, roughly 0.9 miles off. This sits inside Pinkney Hill Preserve, so read the reserve notices first. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check whether a boat is allowed before you tow one. Fishing rules and camping rules are set separately here. Failing this one, try Bear Hill Pond, 1.6 miles away. Treat Old Pembroke Reservoir as unsettled until someone local tells you otherwise.
