From this a "check average permanent <br /> <br />pool storage" is comp\J:ted by addJ.ng one hall' of the diff'Orence of <br /> <br />'the credit ob-tained from the specified nurnb8r of shares and the <br /> <br />evaporation (it may be negative if the evaporation is greater than <br /> <br />the credit). If the "chec}<;: average permanent pool storage" agrees <br /> <br />\vith the assumed value, the computations for ,the next period are <br /> <br />begun, but. if not, a nc\,] average p~rmCtnen.t pool s"tor2.g0 is assumed, <br /> <br />and "the computat.ions aLe repea"ced. unt.il i.:he two ag::cec. <br /> <br />Tables 1 and 2 sUllillla:d.ze the resul ts of compucat.:i.ons <br /> <br />made by the program using historic conditions of compac.t years <br /> <br />19t19-.68 (20 ye<:trs) and assuming c_he state purchases 1200 and 1625 <br /> <br />shares of the Las Animo,s Ditch Company, respectivel1', C):edit that <br /> <br />would, have been obtained durinS. the June 1965 flood was negleo ted. <br /> <br />Table 1. shows tha.t during 15 of the 20 years 1:he permanent pool <br /> <br />Vlould drop be1.m17500 ac-ft and that during 8 of the 20 years it. <br /> <br />would drop belo\'l 5000 ao.-f1:.
