Long Hollow Reservoir <br />Feasibility Study <br />• 14 years, with an average fill of 3,540 AF per year. LHR will release all or nearly all stored <br />water in 10 of 14 years. <br />TABLE 3.2.2-1 <br />La Plata River at Hesperus (Ranked Flows From 1989 Through 2002) <br />~ <br />• <br />Year Annual Discharge <br />~A-Fl' Rank Dry Percent Dry <br />~ 1 2002 6,231 1 1 <br />~ 2 1996 15,424 8 9 <br />3 1990 15, 818 9 11 <br />4 1989 19,638 17 20 <br />5 2000 20,049 22 26 <br />6 1998 24, 020 29 34 <br />7 1994 24,973 31 36 <br />8 1991 27, 305 . 37 44 <br />9 2001 27,837 39 46 <br />10 1999 31,351 44 52 <br />11 1992 35,048 51 60 <br />12 1995 43,079 64 75 <br />13 1997 47, 330 75 88 <br />14 1993 47,991 76 89 <br />Total number of ears 85 <br />Avera e dischar e AF over 14 ears 27,577 <br />Avera e dischar e AF over 85 ears 31,888 <br />Median dischar e AF over 14 ears 26,139 <br />Median dischar e AF over 85 ears 29,970 <br />Notes: <br />'Gauge ID #9365500 from Colorado's Decision Support Systems (CDSS). <br />3Dry ranking out of 85 years (i.e., out of 85 years, 2002 was: the driest}. <br />Dry percent out of 85 years (i.e., out of 85 years, 52 percent were drier than 1999). <br />The model also simulated the amount and timing of releases from LHR to deliver water to New <br />Mexico at the Colorado-New Mexico State Line gauge, as required by the Compact, while <br />allowing Colorado ditches on the La Plata River to divert in priority by exchange without <br />impacting Compact deliveries. A 300-AF Compact Reserve Pool in LHR was used to deliver <br />water to New Mexico during the mid-summer low-flow period when the La Plata River in <br />Colorado often must be administered as a split river. <br />991-077.120 Wright Water Engineers, Inc.
