Earth Month Part 2: The Return of Trout. Please come help add brown trout to the Kayaderosseras Creek! Friends of Kayaderosseras and Avery’s Trout Hatchery Fisheries will collaborate to bring hundreds of new fish to the Kayaderosseras at Kelley Park in the Village of Ballston Spa at 10 am TOMORROW (Sunday, May 1). We need you to join us with a bucket, and carry the young fish the last 20 feet to add them to the creek! Lots of fun, and a great way to celebrate and contribute to Earth Month.
