  22. 22. Colorado River Drought • 2000-2013 was the driest 12-year period in the 100-year historical record (WYs 2009 and 2010 data are estimated) • Tree-ring reconstructions show more severe droughts have occurred over the past 1200 years (e.g., drought in the mid 1100s) • Observed 2013 April through July runoff was 163% of average as of September 6 • Not unusual to have a few years of above average inflow during longer-term droughts (e.g., the 1950s)

  24. 24. April 2014 Watershed Management -- The Colorado River Minute 319
  25. 25. As part of the ongoing dialogue on Colorado River issues, delegations from the United States and Mexico worked over three years to reach an agreement on a set of cooperative measures for management for the next five years. Principals to the agreement: Seven Colorado River Basin states, representatives from the U.S. Department of State and the U.S. Department of the Interior, U.S. IBWC, Mexico IBWC, and Bureau of Reclamation Commissioner. Minute 319 demonstrates commitment and the potential opportunities for future cooperation between the United States and Mexico on water conservation, system operations, environmental restoration, and new water sources projects.
  26. 26. The five-year agreement approved by both governments provides for a series of joint cooperative actions between the United States and Mexico. Elements of the agreement include: •Implementing efforts to enhance water infrastructure and promote sharing, storing, and conserving water as needed during both shortages and surpluses; •Establishing proactive basin operations by applying water delivery reductions when Lake Mead reservoir conditions are low in order to deter more severe reductions in the future; •Promoting the ecological health of the Colorado River Delta;
  27. 27. •Extending humanitarian measures from a 2010 agreement, Minute 318, to allow Mexico to defer delivery of a portion of its Colorado River allotment while it continues to make repairs to earthquake-damaged infrastructure; •Establishing a program of Intentionally Created Mexican Allocation (ICMA) whereby Mexico could temporarily reduce its order of Colorado River water, allowing that water to be delivered to Mexico in the future; Establishes a pilot exchange program under which U.S. entities assist in funding water infrastructure and environmental projects in Mexico. These investments provide water benefits to the U.S. agencies in exchange for their funding and generate water for Mexico.

  29. 29. WaterSMART Secure and Manage America’s Resources for Tomorrow
  30. 30. WaterSMART (Sustain and Manage America’s Resources for Tomorrow) Established by Secretarial Order 3297 in February 2010: “To secure and stretch water supplies for use by existing and future generations to benefit people, the economy, and the environment…”
  31. 31. Reclamation’s WaterSMART Programs • Climate Change Studies and Adaptation – West-Wide Climate Risk Assessments – Basin Studies – Landscape Conservation Cooperatives • Water Conservation and Water Management – WaterSMART Grants – Title XVI Water Reclamation and Reuse Program – Cooperative Watershed Management Program • WaterSMART Clearinghouse
  32. 32. The Secure Water Act (Subtitle F of Title IX of P.L. 111-11, March 2009) • Authorized creation of Climate Adaptation Program • Expanded authorization for water management improvements • Requires reporting to Congress on impacts to water supply • Addresses water data enhancement by the USGS
  33. 33. SECURE Water Act Report • In April of 2011 Reclamation submitted the first report to Congress required by Section 9503(c) of the SECURE Water Act. • The report includes present quantitative projections of future temperature, precipitation, snowpack, and water supplies; as well as a qualitative discussion of impacts to future demands, water deliveries, floods, ecological issues, and hydropower across eight major Reclamation river basins developed through the WWCRAs. • Future reports under the SECURE Water Act will incorporate more information developed through the Basin Studies as they are completed.
  34. 34. Reclamation Components of WaterSMART • WaterSMART Grants – Water and Energy Efficiency – System Optimization Review – Advanced Water Treatment – Climate Analysis Tools • Basin Study Program – Landscape Conservation Cooperatives – West-Wide Climate Risk Assessments – Basin Studies • Title XVI • Cooperative Watershed Management Program • WaterSMART Clearinghouse

  37. 37. West-Wide Climate Risk Assessments • Conducted by Reclamation • Reconnaissance-level water supply and demand analyses in eight Reclamation river basins • Projections of climate change impacts to water supply and demand and baseline risk assessments to evaluate the impacts of climate change to water uses • Baseline for more in-depth analyses performed through Basin Studies
  38. 38. Basin Studies • Purpose  to work with state and local partners in the 17 Western States to evaluate future water supply and demand imbalances in a changing climate • Basin Studies Include: – Assessments of the risks and impacts of climate change on water resources, and – Development of potential mitigation and adaptation strategies to meet future demands
  39. 39. FY 2011 Basin Studies Highlights • Reclamation selected four full Basin Studies and three plans of study in FY 2011, for a total of over $1.8 million in Federal funding. • The Yakima River Basin Study was completed in FY 2011, and a final report addressing the requirements of Section 9503 of the SECURE Water Act has been completed. • In June of 2011 Reclamation released the first Colorado River Basin Study Interim Report. The interim report provides a quantified assessment of four water supply scenarios.

  51. 51. Knowledge improvement • Science institution in USGS • Competitive awarding of contracts (peer review) • Development of conceptual models • Careful consideration of Adaptive Management program protocols – How should managers and scientists interact? – How should recommendations or decisions be made? – External protocol evaluation panels – Oversight from Science Advisors
  52. 52. High Flow Test
  53. 53. Status of selected resources • Water compact requirements continue to be met • Greater aquatic productivity in the Lees Ferry reach • Increased Lees Ferry rainbow trout and more trout throughout the Grand Canyon • Increasing population of endangered humpback chub • Temporary beach-building followed by ongoing erosion of sediment resources and cultural resource sites
  54. 54. Stakeholder Cooperation • Disparate interests and values remain, but willing to engage, discuss and plan • Major experiments agreed to and recommended to Secretary of the Interior • Willingness to look beyond dam operations for resource protection • Development of comprehensive plan for humpback chub recovery actions
  55. 55. Watershed Management - Conclusion • Stakeholder Cooperation • Long-Term Commitment to Process • Willingness to Look Beyond Your Own Agenda • Willingness to Look at Other Point of View
