Congrats to Annalise Hollosy, 2014 Butterfly Festival Design Contest winner!

12th grader Annalise Hollosy is a student at Hopewell Valley Central High School. Her design creatively depicts our theme of Flying Colors, celebrating the splendor and vibrancy of the butterfly. This theme reflects the changes that are taking place at the Watershed, including a new LEED Platinum environmental center and a redesigned trail network.

Thanks to all our local high school and middle school students who submitted artwork for this contest. We were amazed and inspired by the talent and creativity that went into all submissions, and our judges had a very difficult time making a decision.
