<br />Justifiable flood-controt, expenditure
<br />Flood control benefits, as estimated by the Corps of Engineers, were
<br />used as the I'ustifiabl~ flood-control expenditure. These 11l1ve bee.n
<br />evaluated on y for the. Navaho unit and are estimated at $1,135,000
<br />as the present worth of $31,000 annually over 100 years at 2% percent
<br />interest. No estimate was made of the cost of the cheapest alterna-
<br />tive means of providing flood control for considemtion as the justifiable
<br />flood-control expenditure as the cost of such an alternative would far
<br />exceed the anticipated flood-control benefits.
