<br />9. "Est1mated benefits from the flood control phase of the comprehen-
<br />sive plan are based on studies or the additional flood regulation and sed-
<br />iment control that would be provided by the impratementa with full consider-
<br />ation ot the effects of ex1et1ng and authorized improvements 1n the basin.
<br />The requiremente tor strict compliance with the provisions of the Rio Grande
<br />Compact end far m1n1mum water 1088e8 were obeerved in the8e 8tudies. Direct
<br />and indireot fiood control benefits r8sul ting from the prevention or future
<br />flood. damages, including those from stream bed aggradation and deterioration
<br />or capital investments dependent on the economic weltare or agricultural
<br />production, are estimated to total $3,743,700. Benefits arising from the
<br />production or higher value crops as a result of flood control improvements
<br />ore e.t1lllated at 1593,100. The evaluated annual benetits total 14,336,800.

<br />benefits to estimated annual costs 18 1.2. Re concludes that the flood
<br />control phase or the oompreheneive plan or improvement i8 eoonomice.1ly
<br />justified in iteel!, and, 1naemuch as flood protection tor the valle1 areas
<br />is a condition precedent to succes8tul irrigation development, he recom-
<br />mend. that the comprehel1lOive plan be approved and that the flood control
<br />improvements be authorized tor construction b::r the Federal government,
<br />subjeot to operation in accordance with the terms of the Rio Grande Compaot,
