  2. City of Amarillo • Amarillo owns approximately 253,000 acres of groundwater rights • All major rights in the Ogallala Aquifer • Groundwater Rights are less than 75% developed • Amarillo is one of eleven members of the Canadian River Municipal Water Authority • “own” approximately 38% of Lake Meredith allocation • “own” approximately 40% of Roberts Co. Well Field allocation • CRMWA supplies approx. 65% of annual requirement • Average annual use approx. 47,500 a.f. • Estimated lifespan of supply = 100 to 230 years (variance based on CRMWA & Lake supplies)

  3. Roberts Co. Rights 85,556 acres Hartley Co. Rights 91,000 acres Potter Co. Rights 41,000 acres CRMWA Rights 265,000 acres Carson Co. Rights 28,000 acres Randall Co. Rights 7,000 acres GMA 1 Amarillo

  4. Competing Interests? • Groundwater Conservation Districts • Panhandle GCD @ 1 af/yr • North Plains GCD @ 2 af/yr • High Plains GCD @ spacing • Groundwater Management Area #1 • 3 DFC’s • Hartley County Area – 40% remaining in 50 years • Roberts/Ochiltree/Carson/Potter/Randall – 50% in remaining in 50 years • Hemphill – 80% remaining in 50 years • DFC/MAG – how will it affect us?? • Over 75% of Amarillo’s groundwater is being held for future use • Does the current multiple DFC account for future use? • MAG – how will it be applied? • MAG – what if all MAG is being ‘used’ due to higher allowable withdrawals?

  5. NPGCD – 2 af/yr PGCD – 1 af/yr NPGCD – 2 af/yr PGCD – 1 af/yr HPUWCD – Spacing 50% - 50 Yrs Hemphill UWCD 80% - 50 Yrs 40% - 50 Yrs 50% - 50 yrs Amarillo GMA 1 50% - 50 Yrs

  6. Major Issues • Amarillo’s major issue is preserving groundwater for the future • GCD’s provide the best method of ensuring some type of equal access • Original GMA process included stakeholders as decision makers – not currently included • Application of MAG could actually prevent future development of water held for future use • Time will tell – GMA 1 is working well and moving quickly • Implementation discussions are needed to develop further plans
