  2. 2. Leo A. W. Wiegman! About this slide show! Environmental communications! Croton-on-Hudson, NY! 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 < > 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 <>. Sometimes, it is best to let the pictures tell the story. # # # Use of images from this slide show in any other format requires permission: contact To cite this slide show, please use: Wiegman, L (2008) Slide Show on Croton River Gorge for Teatown Board of Trustees, February 2, 2008
