<br />Period of Study
<br />
<br />The study period \'IC.S lil.1i ted to t:1e yenrs 1933 through 1946 [IS
<br />the necess~ry records ~cre ineomplete for tho yonrs prior to 1933.
<br />
<br />Tho irrign'ced ncroc.;e on the Ftn krnnio Di-/i sion of tho North
<br />Plc.tto Project c.l1ounted to 7G,315 ncres in 1926. By 1933, the
<br />irrigo.ted "crec(!;o hnd incrnc.scd to 99,369 "cres, nnd in 1946 n"s
<br />98,028 c,cre8. Irri@;c,tion in the diyision h[ld c,chieved a re"scnc.ble
<br />degree of mnturity "nd stability by 1933,
<br />
<br />W"ter su;)ply f.nd precipi i;r.tion (~uring the period 1933,,46 were
<br />below the Ions time "ver"So with 19j4 Qnd 1940 ye"rs of severe welter
<br />shortDse for the North Phtte Froject. The ~ver"be inflow into
<br />P"~hfinder Reservoir from 1896 t~lrough 1946 I'I"S 1,300,000 acre-feet,
<br />This comp"l'es to c.n nnnuc_l inflo"1 of 924,000 "cre-feet durin~ the
<br />period of study, The maximum inflow since 1896 was 2,500,000 acre-
<br />feet in 1899; the m[lxim~ since 1933 was 1,335,000 "cre-feet in 1938.
<br />The minimum P,~.thfinder i.nflow since 1896 IVLS 332,200 acre-feet in
<br />1934, second lowest vms 572,700 c.cre-fect in 1940, third 10"lest
<br />690,200 ncre-feet in 1939, c.nd fourth lonest 696,200 acre-feet in
<br />1935, all of wllich [Ire included in the period of study. T::is period
<br />thus reflects the most severe conditions of n~ter supply on record,

<br />Units
<br />
<br />The unit of measurement used throClghout this report, unless other-
<br />wise noted, is one t.housGnd c.cre-fetJ:t, c[\.:!.~ried to (Ine decimf'_l pl::~ce.
