• Tackle & Baits

  Whether the bank is open is not something our records settle. Parking within half a mile means no long carry with tackle. There is a mapped landing stage half a mile away. A picnic area is mapped about half a mile away. There are toilets mapped about half a mile away. Some banks are open only from a marked point. Keep proof of licence with you rather than in the car. If the gate is shut, East Reservoir at 0.4 miles is the nearest alternative. Confirm before you fish Main Reservoir.
