<br />level reevaluation of the flood problems on Boxelder Cre.;,k, Studies conducted on
<br />Spring Creek in 1988 by the City of Fort Collins indicated flood control measures would
<br />be feasible in some reaches of Spring Creek, and the City has constructed flood control
<br />measures between College Avenue and the BurlinglOn Northern Railroad (BNRR).
<br />
<br />STUDY ALTlIORITY
<br />
<br />Authority for this study is contained in a resolution by the Committee on Public
<br />Works of the United States Senate, adopted 9 May 1963, which reads as follows:
<br />
<br />"Resolved by the Committee on Public Works of the United States Senate,
<br />that the Board of Engineers for Rivers and Harbors, created underScction 30f
<br />the River and Harbor Act, approved June 13, 1902, be, 'and is hereby, requested
<br />to review the reports of the Chief of Engineers on the Missouri River and Trib-
<br />utaries, published as Hou>c Document numbered 23H, seventy-third Congn.:ss;
<br />House Document numbered 475, sc_enty-eight Crmgress; and other p;::rtinent
<br />reports, with a view to determining whether the existing project should be mod-
<br />ified in any way at thepre,.,n! time in the interest of flood control, navigation,
<br />hydroelcctric power, water supply, water quahly control, drainage, recreation,
<br />fish and wildlifedcvclopment, and allied purposes, coordinated with develnp-
<br />rncnt of re1atcd land resources.
<br />
<br />Consequently, the scope of this study was reduced to an evaluation of the flood
<br />problems on Dry Creek and included only a cursory review and update of the flood
<br />problems and potential solutions on Boxelderand Spring Creeks,

<br />The studies conducted were of reconnaissance scop;:: and were conducted in sufii-

<br />solution to the flood problems on Dry Creek. These studies were based on information
<br />from previous engineering STudies, available mappinganll other existing data, general
<br />ficldinspedions, and judgment basell on standatd engineering practice s. A new hydro-
<br />logic analysis for Dry Creek was completed. Additional field surveys, tu~~,.lgral!hie
