Next, a small projects loan application <br /> <br />report to the U.S. Bureau of Reclamation (presently the <br /> <br />Water and Power Resources Service) was prepared (PL9S4). <br /> <br />This report identified those improvements that would be <br /> <br />financed under the loan and those improvements that would be <br /> <br />financed by the District. Once the loan was approved by <br /> <br />Congress, design was begun and the improvements constructed. <br /> <br />The master plan had several unique features, including: a <br /> <br />pu~ped-storage reservoir for additional water supply; lining <br /> <br />or enlargement of 204 km of laterals and canals, improvement <br /> <br />to 30 major structures; and an on-going annual capital <br /> <br />expenditure program to improve lateral structures. <br /> <br />In most areas of the State of Nebra&~a, g~ound water levels <br /> <br />have declined significantly in recent years due to increased <br /> <br />well irrigation. In most areas of the District, however, <br /> <br />ground water levels have risen significantly. A detailed <br /> <br />ground water study was conducted to determine if conjunctive <br /> <br />use was possible and to determine if the drainage problems <br /> <br />could be alleviated. A ground water model was developed for <br /> <br />the service area to simulate future conditions under various <br /> <br />plans for development. The model was used to layout the <br /> <br /> <br />proposed new facilities and did verify that the concept of <br /> <br />conjunctive use was viable. The model identified areas <br /> <br />where canal lining was necessary to reduce recharge to the <br /> <br />ground water system and where lining was not needed because <br /> <br />-12- <br />
