<br />Since 1914 the United St"tes Geological Survey and United States
<br />ReclanLOtion S0.rv1.ce have lIRde many otudies, investi,~ations, and sur-
<br />veys of water supply, storage sites, projects, and arable lands of
<br />every State in the basin.
<br />
<br />~
<br />
<br />At the present time the Boulder C=yon reservoir site of 25,000,000
<br />acre-feet capacity is being investigated and studied. This site lies
<br />between Nevada and Arizona at the mouth of the Virgin River, and if
<br />built will control the entire lower river o.nd equalize and control the
<br />flow for all undeveloped i rrigab1e lands in the lower basin. The
<br />Boulder Canyon site (if feasible) will serve a three-fold purpose, viz:
<br />largely solve t he flood problem or the lower river, equalize for i~ri-
<br />gation requirements, and also provide equalization for hydro-power de-
<br />volopment.
