Peconic River Professional Review and Guide
"Running from west to east for roughly 15 miles to feed Flanders Bay, this stream is dammed in several places, creating warm-water impoundments.
The state stocks about 300 brown trout ranging from 9 to 14 inches into the headwaters annually. They hit worms and nymphs. The river’s bread-and-butter fish is the largemouth bass. Ranging anywhere from 12 to 22 inches, they take anything from Jitterbugs and Hula Poppers worked on still summer evenings to buzzbaits, spinnerbaits, and lipless crankbaits such as Cotton Cordell’s C-29 Super Spot Minnows. Chain pickerel range from 15 to 25 inches and voraciously attack jerkbaits and worms on spinner harnesses. Yellow perch running from 6 to 12 inches and black crappies of 8 to 10 inches are plentiful; try jigging Beetle Spins and 2-inch curly-tailed grubs on bottom or swimming them through the water column.
Key species: Brown trout, largemouth bass, chain pickerel, black crappie, and yellow perch."
