Lake Watershed And Environmental Flows

Red River Valley Association Meeting June 1, 2016

Richard Lowerre Institute Focus on Talk

Why and How of Restoring and Protecting Instream Flows For Environmental Purposes Caddo Lake Watershed

Natural History of Caddo Lake

 The on the Red River  About 100 Miles Long, Moving 1 Mile/Year

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, and watershed.  Ramsar designation  Caddo Lake National Wildlife Refuge  Protection of Instream or Environmental Flows www.caddolake.us 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 The Ramsar Convention on Wetlands

Signed in Ramsar, Iran in 1971

Over 160 Countries Have Joined

Over 2000 designated “Wetlands of International Importance,” with 160 million hectares

Caddo Lake designated in 1993 U.S. Fish & Wildlife Service, International Affairs

1. Izembek National Wildlife Refuge(NWR) 2. Forsythe NWR 3. Okefenokee NWR 4. Ash Meadows NWR 5. 6. Estuarine Complex 7. Bottoms 8. Cache-Lower White Rivers 9. 10. 11. Estuary 12. Pelican Island NWR 13. Caddo Lake 14. Estuary 15. Cache River-Cypress Creek Wetlands 16. Sand Lake NWR 17. 18. Quivira NWR 19. 20. Tijuana River National Estuarine Research Reserve 21. Grassland Ecological Area 22. Kawainui and Hamakua Marsh Complex

From 22 sites – 1.3 million hectares of wetlands

What Ramsar Does/Does Not Do Ramsar Does: Ramsar Does Not:

 Encourage nations to  Impose restrictions on promote wetlands nations and landowners conservation and designate wetlands of  Affect sovereignty rights international importance. – site listing is voluntary

 Provide guidelines,  Act as a regulating entity educational materials, & or a UN convention proposals for protection of wetlands.

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.) Sustainable Rivers Project Goals of Instream Flows Project for the Caddo Lake Watershed in 2004 1. 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 ;

3. Official recognition of the flow regimes in programs; and

4. A Long-term Adaptive Management Process 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
