"Formerly called Minnesetah River, this stream starts out mildly in Penn Yan and picks up speed as it drops 300 feet on its 6-mile trek to Seneca Lake.
After a hiatus of nearly ten years, the state started annually stocking the stream again in 1999 with about 1,000 browns ranging from 8 to 13.5 inches. However, most anglers go up this creek searching for lake-run fish ranging from 3 to 10 pounds. Seneca Lake browns, mixed with a few landlocked salmon, start running around November and can be found all the way up to Cascade Mills, the first waterfall impassable by fish.
Rainbows about the same size run the same stretch in early April. Both species hit worms, egg sacs, streamers, silver Dardevle spoons, and white Rooster Tail spinners. From the mouth to Cascade Mills, the minimum length for salmon and trout is 15 inches, and the daily limit is three in any combination."
