The irrigation investi- <br />gations included studies of the irrigation water supply and utilization, <br />classification of the project lands, and economic studies for estimating <br />the payment capacity of the lands and the irrigation benefits. Other <br />studies were confined to a survey of the existing irrigation facilities <br />which revealed that their general condition is good and that they will <br />be adequate for serving the project lands after minor improvements <br />are m~de as provided for in the OM&R estimates used in the economic <br />analysis. <br /> <br />In past operations, the irrigation water supplies for the area as <br />a whole have been inadequate and ill-distributed--the average annual <br />quantity amounting to 61.0 percent of the total requirement with <br />late season supplies being consistently unavailable. Construction <br />of the project and restricting deliveries to irrigable lands only <br />will increase the annual average supply to 83.0 percent of the total <br />requirement. <br /> <br />The Purgatoire River Conservancy District has been organized for <br />the purpose of contracting for repayment and for management of the <br />project water supply. <br /> <br />vi <br />
