Keynote Speaker: As the Colorado River Compact turns 100 years old, Southern Nevada Aims to Reshape its Water Future

Colby Pellegrino, Deputy General Manager of Resources for the Southern Nevada Water Authority

In the past 100 years since the Colorado River Compact was signed, the Colorado River Basin has seen many changes: dams, environmental protections, human impact, periods of high flows and decades-long drought. Among its most remarkable, a decades-long megadrought affecting snowfall and runoff has resulted in significant water level declines at major system reservoirs, including Lake Mead and Lake Powell. For the seven U.S. states who depend on this river for municipal supplies and agricultural demands, these drought conditions present a looming threat to their economies, landscapes, and livelihoods.

 

The elevation of Lake Mead – the United States’ largest reservoir - has dropped by nearly 170 feet since 2000, prompting the Secretary of the Interior to make the first-ever shortage declaration. The risk of shortage remains high in future years and the federal government is projecting a high probability that Lake Mead water levels will continue to decline. While the ongoing work of federal, state, and municipal water partners have helped to slow the decline of Lake Mead water levels, through the 2007 Interim Guidelines for the Coordinated Operation of Lakes Mead and Powell and the 2019 Lower Basin Drought Contingency Plan, the Basin is reaching a critical point that requires more work and difficult decisions.

 

With the current state of the river system, the aridification of the southwestern United States, the 100-year-old Colorado River Compact, its framework and related agreements and policies will be at the heart of many discussions and debates in the coming months. At the center of the framework is the Interim Guidelines, the agreement that was signed in 2007 that shaped today’s Colorado River operations. These guidelines have provided the path forward to cooperation among the river’s users, but with the guidelines set to expire in the coming years and users facing unprecedented inflow projections, river users are facing an unchartered path forward.

E

very user has a unique stake and perspective within the Colorado River system: from urban demands to meet the West’s growing population centers to expansive agricultural operations, and the states have been asked for additional conservation in an amount that yields between 2 million to 4 million acre-feet, representing nearly a third of the river’s total use.

 

In Southern Nevada, the Southern Nevada Water Authority (SNWA), the region’s wholesale water provider, and its member agencies has been reducing demands since drought effects were first realized in the early 2000s. For the past 20 years, Southern Nevada has reshaped how the community grew and continues to rewrite its future and to reduce the impacts of drought and climate change on water supplies and facilities through securing infrastructure, diversifying water resources and reducing demands through a comprehensive water conservation program.

As the southwestern United States moves into the next decade and beyond, unprecedented changes will continue to occur, within municipalities and agriculture, to help secure one of the desert’s most precious resource.

Bio: After joining the agency in 2003, Pellegrino served as an instrumental part of the Water Resources division, supporting Colorado River modeling efforts to anticipate changes caused by climate change, reduced flows, and other inputs. In her current capacity, she is responsible for the management of the Water Authority’s water resource portfolio, which includes protecting Nevada’s interests and rights to Colorado River water through interstate negotiations, developing regional water conservation programs, managing groundwater resources, and water resource planning. Pellegrino also serves on the Board of Alliance for Water Efficiency, a nonprofit organization dedicated to the efficient and sustainable use of water and water conservation advocacy throughout North America. A native of Las Vegas, she earned her Bachelor of Science degree in civil engineering from the University of Nevada, Las Vegas, and her Master of Business Administration from Mississippi State University. Pellegrino has two children and is an avid cook, hiker, and outdoors enthusiast.
