Groundwater inflow in the unconfined aquifer to the closed basin from the southern groundwater <br />divide. <br />2. Irrigated Crop lands. <br />3. Irrigated pasture lands & natural streamside vegetation (389 kaf/yr), undeveloped land (73 <br />kaf/yr). <br />4. Surface water inflow was estimated from Hearne's total estimated inflow from the San Juan Mtns <br />by prorating reported values in Table 7 of the report. <br />5. Groundwater inflow was estimated by subtracting estimated surface water flows from estimated <br />total water inflows. <br />6. Beneficial CU includes 967 kaf/yr from agriculture use, 2 kaf/yr from livestock use, 5 kaf/yr <br />from M&I use, and 5 kaf/yr from reservoir evaporation. <br />rg_task8-1_2001-08.doc 2 of 19 Apri16, 2001 <br />
