description of the respective projects that can be found in the Program Document <br />Water Plan: <br />a. Nebraska's Environmental Account in Lake McConaughy (NEA) <br />(Attachment 5, Section 5) <br />b. Wyoming's Pathfinder Modification Project (PMP) (Attachment 5, <br />Section 4) <br />c. Coloradds Initial Water Project (Tamarack I) (Attachment 5, Section 3) <br />Table 3-1 entitled, "Average Yields", depicts estimated quantities of Program water <br />that will be available in Average, Wet, and Dry years. The following yields are based <br />on model runs used in the EIS for the Program for the 1947 through 1994 hydrologic <br />period. The yields of the NEA and PMP are achieved in Lake McConaughy. The <br />Tamarack I contributions represent an average annual volume as presented in <br />Attachment 5, Section 3 of the Program Document. The yields of Tamarack I are <br />based on increased flows below the Western Canal in Nebraska. <br />Table 3-1 <br />Average Yields <br />(ac-ft x 1,000) <br /> Avg. Annuai Avg.

It is envisioned that the remaining 50,000- <br />70,000 ac-ft of water per year will be obtained from an alternative(s) selected from <br />those identified in the Program Document Water Plan (Attachment 5, Section 6). <br />BDWLE Page 6 of 58 January 29, 2008 <br />PRRIP - Draft Water Management Study, Phase I
