A long productive spell runs morning through afternoon. Make the first hour count and build on it. Autumn rewards covering water while the fish roam.

Upper Reservoir is one of the Norfolk County listings for Massachusetts. The water sits 302 feet up. Nearest town is Foxborough, 1.5 miles off. Wrentham lies 2.6 miles off, Mansfield another 3.8 miles. Nearby, in order: Lakeview Pond 0.3 miles off, Sunset Lake the better part of 0.7 miles, Crocker Pond 0.9 miles off, Mann Pond the better part of 1.4 miles and Neponset Reservoir 2.1 miles off. Two sets of local rules meet not far from this water.
Nothing we hold settles how deep this runs. Built water gives depth close in, which suits a bank angler. The arms fish better than the open middle whenever the water is up. Reported across Norfolk County: bluegill, pumpkinseed, chain pickerel and yellow perch. Those are county-wide records, so not every one of them will be in this water. The near bank of Upper Reservoir is often the one people ignore.
Expect July to average close to 71°F, with January the cold end at about 26°F. Temperature moves within a narrow band, and so does the fishing. Hard water here is never dependable, so check for yourself before stepping out. February into May fishes hardest as the water warms. Time your trip to Upper Reservoir by conditions rather than dates.
Whether the bank is open is not something our records settle. The car has to stay half a mile away, which shapes how much tackle you bring. The water borders Cocasset Brook Greenbelt, so reserve rules are likely to apply. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. A phone call first saves an afternoon. Where parking is tight, arriving early solves most problems. Lakeview Pond at 0.3 miles is the sensible second choice. For Upper Reservoir, the notice at the access point is the final word.
