<br />III. COMPARISON OF STATE/REGIONAL FUTURE (SRF) <br />AND MODIFmD CENTRAL CASE (MCC) <br /> <br />Comparisons of the State-Regional Future (SRF) and MOdified <br />Central Case (MCC) data can be made only by ASA's and Regions since <br />MCC data are only on that basis. All of the Rio Grande Region in <br />Colorado is in ASA 1301. The New Mexico Assessment area includes <br />ASA 1302 except for E1 Paso and Hudspeth Counties in Texas, plus <br />all of ASA 1304. Texas includes the two counties of E1 Paso and <br />Hudspeth in ASA 1302, and all of ASA's 1303 and 1305. Future Na- <br />tional Water Assessments would be enhanced by including State data <br />in WRC summaries. <br /> <br />Data are not uniformly available from the three States of the <br />Region for comparison in table or figure summaries as provided by <br />WRC. Accordingly, the following Figures 1 through 4 include compar- <br />isons where data are available, and notations of "NA" are shown <br />where data are not available. <br /> <br />Data submitted by the States of New Mexico and Texas for po~- <br />tions of ASA 1302 have been combined to prepare the State Regional <br />Future data used in Figures 1 through 4. All other ASA's in the <br />Rio Grande Region are within one State. <br /> <br />The water supply sumnaries both for the SRF and MCC compari'::, <br />sons in Figure 4 are based on the following equations: <br /> <br />(1) Depletions = Consumptive Use + Evaporation - Imports + <br />Exports. <br /> <br />(2) Natural MOdified Flow = Present MOdified Flow + <br />Depletions - Groundwater Withdrawals. <br /> <br />(3) Future MOdified Flow = Natural Modified Flow _ <br />Depletions + Groundwater Withdrawals. <br /> <br />': "j ',:.: ,~:~ <br />I..;.......".' .._ <br /> <br />14 <br />
