• Where to Fish on Allegheny Reservoir

  No figure exists for depth, so let the water show you. Held water runs deepest at the wall and shallows back to the inflow. Inflow corners move water, and moving water gathers fish. Warren County records list brown trout, brook trout and walleye among the fish reported. Species recorded across the county may be limited to a few waters. On Allegheny Reservoir the quiet end is the one worth the extra effort.

• Seasonal Patterns

  The range across the year is 22°F to 67°F. The middle months are generous; the ends are demanding. Hard water holds through the cold months, breaking up near early April. On the long-run averages the water opens up around early April and starts locking again about mid December. Spring is short and heavy here; autumn is longer and steadier. Expect Allegheny Reservoir to follow that timing.

• Tackle & Baits

  We hold no note on access for this one. There is a campsite half a mile from the water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Take the rules with you rather than trusting memory. Check whether bait restrictions apply before you buy any. Science Lake at 9.3 miles is the sensible second choice. For Allegheny Reservoir, the notice at the access point is the final word.
