With <br />respect to future estimates, the Colorado State Demographers Office (SDO) indicates <br />demand in the Leadville area will be influenced from growth along the I-70 corridor and <br />the potential reopening of the Climax Mine. Specifically, the SDO projects that Lake <br />County will have a population of about 22,000 by 2035. Of these residents, it is <br />estimated that up to 70 percent (15,400) may live in the Leadville area and be served by <br />the District, which provides a basis for estimating future demands. <br />TABLE 3 <br />COMPARISON OF YIELD AND DEMAND <br />Present 2035 Future <br />DemandlYield Demand/Yield <br />Item Descri tion m d m d <br />Annual Demand 1.25 3.20' <br />Annual Yield <br />Evans Gulch: Direct Flow, Storage, & Elkhorn Shaft (limited by <br />WTP Ca acit 1.00 1.00 <br />Arkansas Wells 0.25 0.25 <br />Net Sur lus/ Deficit 0.00 1.91 <br />Season• Summer <br />Peak Da Demand 2.20 5.00 <br />Maximum Dail Yield <br />Evans Gulch: Direct Flow, Storage, & Elkhorn Shaft (limited by <br />WTP Ca acit 2.20 2.20 <br />Arkansas Wells 0.25 0.25 <br />Net Sur lus/(Deficit 0.25 2.55) <br />Season� Winter <br />Av Dail Demand 1.10 2.80 <br />Av Dail Yield <br />Evans Gulch: Direct Flow Stora e, & Elkhorn Shaft 0.85 0.85 <br />Arkansas Wells 0.25 0.25 <br />Net Sur lus/ Deficit 0.00 1.68 <br />Annual future demand calculated as (15,400 residents x 205 Gal per Day per Capita / <br />1,000,000). <br />z Peak day demand estimated as (Peak Day Factor x Avg Annual Daily Demand) or (1.6 x 3.2). <br />3 Winter daily demand estimated as (Present Avg.
