9 CADDO LAKE INSTITUTE Founded in 1992 by Don Henley A nonprofit corporation for scientific and educational purposes To assist the communities of Caddo Lake to protect the Lake, wetlands and watershed. Ramsar designation Caddo Lake National Wildlife Refuge Protection of Instream or Environmental Flows

10 What We Try to Do Assist the local communities with protection of Caddo Lake and thus, its watershed. Obtain Ramsar designation. Convert the Army ammunition plant to a wildlife refuge. Protect the water quality Address the problems of invasive species Assure adequate flows - amount and timing - to Caddo

11 The Ramsar Convention on Wetlands Signed in Ramsar, Iran in 1971 Over 160 Countries Have Joined Over 2000 wetland designated Wetlands of International Importance, with 160 million hectares Caddo Lake designated in 1993

Grassland Ecological Area 22. Kawainui and Hamakua Marsh Complex From 22 sites 1.3 million hectares of wetlands

14 What Ramsar Does/Does Not Do Ramsar Does: Encourage nations to promote wetlands conservation and designate wetlands of international importance. Provide guidelines, educational materials, & proposals for protection of wetlands. Ramsar Does Not: Impose restrictions on nations and landowners Affect sovereignty rights site listing is voluntary Act as a regulating entity or a UN convention

19 Environmental Flow Project Started in 2004 with the U.S. Army Corps of Engineers, the Nature Conservancy and others To bring scientist and stakeholders together to discuss what might be needed and possible to restore some of the historic functions of Big Cypress (and protect those functions for other rivers in the watershed.)

20 Sustainable Rivers Project

21 Goals of Instream Flows Project for the Caddo Lake Watershed in A consensus recommendation for instream flow regimes for the basin not just below Lake O the Pines; 2. New Operating Plan for releases from Lake O' the Pines to provide more natural flows in Big Cypress Bayou; 3. Official recognition of the flow regimes in Texas programs; and 4. A Long-term Adaptive Management Process

22 2007 Senate Bill 3 TCEQ shall adopt appropriate environmental flow standards for most river basin that are adequate to support a sound ecological environment, to the maximum extent reasonable considering other public interests and other relevant factors. The standards shall be recommended by scientist and stakeholders for each river basin, based on environmental flow regime
