Slide Show on Croton River Gorge for Teatown Board of Trustees, February 2, 2008
The slide show is a visual tour of the Croton River Gorge and its watershed from the dam upriver in winter to the estuary at the
Hudson River down river in summer.
Teatown Lake Reservation < www.teatown.org > is the largest nonprofit nature preserve an environmental education center
in Westchester County. Teatown Lake Reservation is embarking on an ambitious outreach to become an environmental and
educational resource for the five county Hudson Hills to Highlands region.
Under executive director, Fred Koontz, Ph.D., Teatown has secured funding for a multi-year program, “Environmental Leaders
Learning Alliance,” (ELLA) to train local conservation councils and environmental boards in the 39 towns and villages of the 900
square miles of the mid Hudson area. Teatown’s ELLA program will hold its kickoff meeting in mid-2008.
Simultaneously and separately, Westchester County and several communities, led by Croton-on-Hudson near Teatown, are
launching an effort to save the Croton River Gorge and its watershed that drains into the Croton Bay estuary. The estuary is a
federally designated essential fish and wildlife habitat on the Hudson River. The resulting study sets forth a specific Action Plan
of policy recommendations for each of the five municipalities in the watershed to consider. Find the quot;Indian Brook-Croton
Gorge Action Planquot; at < www.westchestergov.com/planning/environmental/>.
Sometimes, it is best to let the pictures tell the story.

drawn from the depths of the reservoir (chutes on the right), as well as from
flow over the gorgeous, stone step spillway on the left (2005).!
