<br />The tables for Pueblo Reservoir were generated by means of the area.capacity program ACAP85, using the least squares method of curve <br />fitting developed by the Reclamation Service Center. This program computes area at 1.0-, 0.1-, and O.Ol-foot increments by linear <br />interpolation between basic data contours. The respective capacities and capacity equations are then obtained by integration of the area <br />equations. The initial capacity equation is tested over successive intervals to check whether it fits within an allowable error term. At the <br />next interval beyond, a new capacity equation (integrated from the basic area equation over that interval) begins testing the fit until it too <br />exceeds the error term. The capacity curve thus becomes a series of curves, each fitting a certain region of data. The final area equations <br />are obtained by differentiation of the capacity equations. Capacity equations are of the form y = al + a~ +a3x2, where y is capacity and <br />x is the elevation above an elevation base. The capacity equation coefficients for the reservoir are shown below (r = 0.000001). <br /> <br /> PUEBLO RESERVOIR 1993 AREA-CAPACITY TABLES <br />EQUATION ELEVATION CAPACITY COEFFICIENT COEFFICIENT COEFFICIENT <br />llUl.lBER BASE BASE Al (COEFFICIENT) A2 (1st TERM) A3 (2nd TEEM) <br />1 4752.80 0 ~O.OOOO 0.0000 3.6364 <br />2 4755.00 17 17 .6000 16.0000 30.2000 <br />3 4760.00 852 852.6000 318.0000 12.7700 <br />4 4765.00 27 61 2761.8500 445.7000 2.6100 <br />5 4770.00 5055 5055.6000 471 .8000 21.9600 <br />6 4775.00 7963 7963.6000 691.4000 10.2600 <br />7 4780.00 11677 11677.1000 794.0000 11.0300 <br />8 4785.00 15922 15922 .8500 904.3000 10.2700 <br />9 4790.00 20701 20701.1000 1007.0000 15.2000 <br />10 4795.00 26116 26116.1000 1159.0000 12.1000 <br />11 4800.00 32213 32213.6000 1280.0000 15.1000 <br />12 4805.00 38991 38991.1000 1431.0000 21.2000 <br />13 4810.00 46676 46676.1000 1643.0000 17 . 0000 <br />14 4815.00 55316 55316.1000 1813.0000 19.2000 <br />15 4820.00 64861 64861.1000 2005.0000 16.2000 <br />16 4825.00 75291 75291.1000 2167.0000 20.1000 <br />17 4830.00 86628 86628.6000 2368.0000 21.1000 <br />18 4835.00 98996 98996.1000 2579.0000 15.8000 <br />19 4840.00 112286 112286.1000 2737.0000 17.3000 <br />20 4845.00 126403 126403.6000 2910.0000 19.9000 <br />21 4850.00 141401 141401.1000 3089.0000 20.9000 <br />22 4855.00 157368 157368.6000 3298.0000 23.2000 <br />23 4860.00 174438 174438.6000 3530.0000 23.3000 <br />24 4865.00 192671 192671.1000 3763.0000 22.9000 <br />25 4870.00 212058 212058.5999 3992.0000 24.6000 <br />26 4875.00 232633 232633.5999 4238.0000 34.9000 <br />27 4880.00 254696 254696.0999 4587.0000 23.6000 <br />28 4885.00 278221 278221.0999 4823.0000 29.2000 <br />29 4890.00 303066 303066.0999 5115.0000 30.9000 <br />30 4895.00 329413 329413.5999 5424.0000 33.4000 <br />31 4900.00 357368 357368.5999 5758.0000 39.6000 <br />32 4905.00 387148 387148.5999 6154.0000 37.8000 <br />33 4910.00 418863 418863.5999 6532.0000 46.6000 <br />34 4915.00 452688 452688.5999 6998.0000 47.7000 <br />35 4920.00 488871 488871.0999 7475.0000 55.2000 <br />The Pueblo Reservoir survey in May 1993 used the range method to obtain the basic data for these tables. Ranges were profiled by standard <br />surveying techniques. The survey was run by personnel from the Reclamation Service Center and Great Plains Region. Reduction of the <br />field data was completed at the Reclamation Service Center in Denver, Colorado. <br />
