3 What is SNWA? The Southern Nevada Water Authority (SNWA) was formed in 1991 to address Southern Nevada s unique water needs on a regional basis

4 SNWA Member Agencies City of Las Vegas City of Henderson City of Boulder City City of North Las Vegas Big Bend Water District Clark County Water Reclamation District Las Vegas Valley Water District

5 Colorado River Overview - Upper & Lower Basins apportioned 7.5 mafy each - Average runoff ~15 mafy - 60 maf of storage - U.S. Bureau of Reclamation serves as water master

6 Colorado River Consumptive Use Nevada 300,000 Colorado 3.9 million UPPER DIVISION 7.5 million acre-feet Arizona 2.85 million Wyoming 1 million New Mexico 850,000 LOWER DIVISION 7.5 million acre-feet California 4.4 million Utah 1.7 million

7 SNWA Resource Portfolio Southern Nevada has historically benefited from two very dependable, accessible and inexpensive resource options: Groundwater in the Las Vegas Valley Colorado River Water

8 Historic Water Use

9 1900 to 1943 Groundwater use only no use of Colorado River

10 1943 to 1971 Beginning use of Colorado River water

11 1971 to 2004 Growing dependence on Colorado River water

12 Water Resource Development Non-Colorado River Resources Las Vegas Valley Groundwater Las Vegas Valley Reclaimed Groundwater % 10% Colorado River Resources Nevada Basic Apportionment Return Flow Credits Surpluses Unused Apportionment (AZ/NV) Arizona Water Bank Southern Nevada Water Bank 0% 90% *Approximate %

13 Early 1990s SNWA formed in 1991 Began an integrated water resource planning process which considered technical aspects and policy aspects Lead to a paradigm shift

14 Mid 1990s: Paradigm Shift Changed from a water accounting process to a water management process Utilize temporary and permanent supplies Create a portfolio of resource options to meet future needs Manage water supply through a water resource plan that is reviewed annually and amended as necessary

15 Integrated Resource Planning Demands Conservation Resources Facilities

16 SNWA Water Resource Plan First issued in 1996 Defines water resource portfolio and priorities for use Reviewed annually and revised as necessary Priorities are adjusted for: Environmental Compliance Availability Accessibility Cost

49 Lincoln County SNWA LVVWD Agreement Divides all pending groundwater applications within Lincoln County into three categories based upon the basin in which each is located: Category One - applications to which the LVVWD retains all right and title Category Two - applications that will be assigned by the LVVWD to Lincoln County Category Three - applications to which the LVVWD will retain all right and title with exceptions

50 Interbasin Transfers Interbasin transfers are allowed under Nevada law The county of origin and the exporter meet to discuss mitigation efforts to address potential impacts caused by the transfer The county of origin, after consulting the State Engineer, can impose a $6 per acre-foot interbasin transfer fee on the exporter to pay for economic development, health or education programs in the county

68 Groundwater Management Program

69 Well Conversion Grant Program More than 200 well users have received assistance Only 5 mandatory connections Mandatory and voluntary connections 85 percent of eligible costs 100 percent of eligible costs, if well user qualifies for public assistance SNWA plugs well at no cost to well user(s)

70 Mandatory Connections Only the State Engineer can require a well user with a temporary permit to connect to a municipal water system By law, the State Engineer can only require connection if: The well fails (drill rig is needed to deepen or replace well) AND The property served by the well is within 180 feet of a water line

71 Permanent Recharge Program Since 2000, more than 7,000 acre-feet of treated Colorado River water has been permanently stored in the Las Vegas basin

72 Plugging Unused Wells Since 2000, more than 100 unused wells have been plugged Most were plugged as part of a well conversion Targets abandoned wells that pose risk to aquifer

73 Conservation Programs Water Smart Landscapes $1 per square foot of turf replaced Over 200,000 square feet converted by well users
