Slack Reservoir near Greenville: Fishing Spots, Seasons and Access

• Overview

  Slack Reservoir falls in Providence County, part of Rhode Island. The coast is 8.8 miles away. It runs to roughly 137 acres — big enough to hold fish away from the bank, small enough to learn. The edge runs 1.8 miles or so, easy to work in an afternoon. It ranks high for size among our Providence County listings. Greenville lies 0.7 miles from the water. North Scituate follows at 2.7 miles, then Johnston at 3.6 miles. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Slack Reservoir

  Depth is unmeasured here, so let the shoreline guide you. Inflow corners move water, and moving water gathers fish. The old creek line under the surface is the feature worth finding. Records held for Providence County cover bluegill, common carp and pumpkinseed. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Work Slack Reservoir in sections rather than trying to cover it.

• Seasonal Patterns

  Between January at about 26°F and July at about 71°F, the water has a wide range to work through. Conditions shift steadily rather than sharply. Cover comes and goes, so treat it with suspicion rather than trust. The hot months push the fishing to dawn and dusk. Anyone fishing Slack Reservoir regularly works to that calendar.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. The nearest car park we can see is half a mile out, so expect a walk with your gear. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A landowner's word beats anything printed elsewhere. Some ground is open by custom rather than by right, so tread carefully. If the gate is shut, Mountaindale Reservoir at 1.7 miles is the nearest alternative.
