• Seasonal Patterns

  Climate normals give 70°F for July and 24°F for January. A solid cap is the normal state through winter. The lid arrives early and lasts until roughly late March. Averages suggest open water from about late March through to roughly late December. Just after the ice goes and just before it returns, the fishing lifts. At Reservoir Number Four the season follows that pattern closely.

  We have no record of the rules that apply on this bank. Parking is not close: half a mile from the bank, and no nearer option is mapped. Somewhere to sit and eat is half a mile out. Purgatory Chasm State Reservation covers this ground, which means extra rules to check. Check whether a boat is allowed before you tow one. Where parking is tight, arriving early solves most problems. If the gate is shut, Swans Pond at 0.9 miles is the nearest alternative. Confirm access to Reservoir Number Four locally before you travel.
