An International River < 1850 s - Small impact of humans on the river > 1850 s - Dramatic changes began to occur 1900s Treaties between Mexico US Convention of 1906: above Fort Quitman, Texas Treaty

3 An International River < 1850 s - Small impact of humans on the river > 1850 s - Dramatic changes began to occur 1900s Treaties between Mexico US Convention of 1906: above Fort Quitman, Texas Treaty of 1944: below Fort Quitman to Gulf Dams constructed Elephant Butte Dam: First major dam (1916) International Dams: Falcon (1954) Amistad (1969) The River Today - Increasing tension over water supply 3

4 Binational Water Management Information System: Rio Grande Basin Motivation Water scarcity over past 10+ years necessitates Determining water availability in the basin Developing new planning tools Providing analysis for improved water management Objectives Develop a comprehensive, bi-national, basin-scale scale database Georeferenced (GIS) Relational Database Organized according to the basin principle Watersheds delineated and hydrologic parameters calculated Hydrologic and related data accessible for analysis (including time t series) Available to stakeholders Mexican and US federal, state, and local organizations Assist in US-Mexican bi-national cooperation concerning water in the basin 4

10 Binational Geodatabase Tracing upstream from Amistad Res. 10

11 Time Series in the Geodatabase Over 5,000,000 time series records today 11

12 Water Quality Geodatabase Related to the Water Quantity Geodatabase Uses binational Water Quality criteria from TCEQ, SEMARNAT, EPA, CNA, IBWC, USGS 12

13 Using the Geodatabase: Physical Assessment Project Objective: Build and Utilize a Whole Basin Water Resources Planning Model to Analyze Physical Opportunities to Improve Water Management in Rio Grande/Bravo Basin Better Satisfy Water Management Objectives While Meeting Currently Unmet Needs in All Sectors,, in All Segments, and in Both Nations 13

Physical Assessment Project Activities Develop Basin-Wide, Bi-National Tools Database and Model to Evaluate Scenarios Develop Scenarios Improved Water Management

15 Physical Assessment Project Activities Develop Basin-Wide, Bi-National Tools Database and Model to Evaluate Scenarios Develop Scenarios Improved Water Management Opportunities Evaluate Scenarios Physical Feasibility (First) Economic and Institutional Feasibility (Second) Generate Recommendations Water Management Improvement Options 15

16 Conclusions Bi-national Geodatabases Created for Rio Grande Basin Water quantity and quality Includes more than 5 million time series records Shared among Mexican and U. S. federal, state, and local organizations Illustrates US-Mexican binational cooperation Bi-national Geodatabase Used in Basin-wide Model to Explore new approaches to improve water management planning in the basin Comprehensive, outcome-neutral, model-based planning System-wide analytical capability (database, planning models, and stakeholder-driven driven scenarios) 16
