<br />lHH987 <br /> <br />. Azotea Tunnel = Rio Blanco Diversion + Little Navajo Diversion + Navajo Diversion <br /> <br />Azotea Tunnel has a maximum capacity of 950 cfs. <br /> <br />. Heron Reservoir Storage = Maximum of live capacity, Minimum of inactive capacity <br /> <br />Pine River Proiect (Vallecito Reservoir) <br /> <br />The main function of Vallecito Reservoir is storage of irrigation water for full service and <br />supplemental supply. CaE flood control regulations and National Weather Service (NWS) runoff <br />forecast are used to determine maximum allowable storage while filling the reservoir. General <br />operation criteria are: <br /> <br />. Maximum release = 2,500 cfs <br />. Minimum release = 20 cfs hydropower penstock <br />. Target elevation on December I = 7,646 feet. <br /> <br />Navaio Reservoir <br /> <br />Navajo Reservoir is the largest Reservoir in the basin. It fulfills all the traditional roles of any large <br />reservoir. It has an in-reservoir diversion facility for NIIP. There is some power generation but it is <br />incidental to the reservoir operation and is not managed for such. CaE flood control regulations and <br />National Weather Service (NWS) runoff forecast are used to determine maximum allowable storage <br />while filling the reservoir. General operation criterial are: <br /> <br />. Maximum release = 5,000 cfs <br />. Minimum release = 250 cfs <br />. Minimum elevation = 5,990 ft. (modeled at 5985 ft, see the Min. Navajo Reservoir Elevation <br />section in Chapter 4.) <br />. Fish release rules are followed during the runoff season (See chapter 6) <br /> <br />Florida Proiect (Lemon Reservoir) <br /> <br />The Main function of Lemon Reservoir is storage of irrigation water for full service and supplemental <br />supply. Reservoir operations must respect direct flow water rights, an instream flow requirement of <br />4 cfs, a Durango M&I demand of 8.9 cfs (capacity), and project demands. The Annual Operation <br />Plan (AOP) uses NWS forecasted inflow and follows CaE flood space requirements. Capacity of the <br />outlet works is 910 cfs. <br /> <br />. Minimum release = Minimum ([4cfs + Durango M&I (max 8.9 cfs)], <br />[Maximum{non-Project Irrigation demand, reservoir inflow}]) <br /> <br />. Maximum release = Maximum ([total irrigation demand], [910 cfs], [supply]) <br /> <br />DRAFT - SJRIP Hydrology Model Documentation <br />June 18, 1999 <br /> <br />48 <br />
