What to tie on at Gregg Mill Road Access (New Boston)
Picked from recent reports for this stretch.
Clouser Minnow (Bass) (Chartreuse/White)
An effective baitfish imitation for predatory species like bass, pickerel, and salmon, which are active in the cooling fall waters.
Woolly Bugger (Olive)
A versatile year-round streamer, effective for imitating leeches and baitfish for predatory species, especially as water cools.
Woolly Bugger (Black/Olive)
With the current extremely high flows on the Piscataquog River, predatory fish like smallmouth bass, largemouth bass, and even larger fallfish will be pushed to the banks and holding areas. This versatile streamer effectively imitates leeches and baitfish disoriented by the fast water.
Clouser Crayfish (Bass)
Crayfish are a primary food source for smallmouth and largemouth bass, especially in rocky river sections. High water can dislodge them, making them easy prey. This pattern excels when stripped along the bottom near structure.
San Juan Worm (Red)
The Piscataquog River is experiencing extremely high flows, and aquatic worms are easily dislodged and washed into the system, making this a prime food source. The red color provides high visibility in off-color water.
Flashback Pheasant Tail Nymph
Mayfly nymphs are always present in the Piscataquog River. This weighted nymph is an excellent general searching pattern for early spring, effective for trout and panfish holding deeper in the water column due to high flows.
Hendrickson Nymph
Hendricksons are a key early spring mayfly hatch in New England, and the nymphs are actively moving subsurface. Even with high flows, fish will be opportunistic feeders, and this is a primary food source for trout and fallfish.
Squirmy Wormy
Similar to the San Juan Worm, the Squirmy Wormy is incredibly effective in high, potentially turbid water conditions, mimicking natural aquatic worms that are abundant after increased flows. Its soft, wiggly action is irresistible to opportunistic feeders.
