<br />(0 <br />CoO <br />C <br /> <br />.- <br /> <br /><.::. <br /> <br />The test hole should be completely cased to insur~ <br />against caving, and an electric log should first be ' <br />made of the hole to determine proper casing setting, <br />perforatLon intervals, and possible zones of undesirable <br />water. Carbonaceous shale and coal beds in the Dakota <br />may contribute undesirable chemical substances to the <br />water; therefore, they should be sealed along with all <br />rock materials above the Dakota. <br /> <br />To determine the hydraulic characteristics of the <br />well, a pumping test of at least 24 hours is necessary. <br />Varying the discharge during this period will help to <br />develop the well, and the drawdown at various pumping <br />rates can be determined. If the capacity of the well <br />is known, a pump of suitable size can be installed and <br />set at a proper depth for the desired yield. The <br />capacity of the well also will determine to a large <br />extent the size of the storage reservoir. A water <br />sample for chemical and bacteriological analysis should <br />be collected during the test, and the water should be <br />analyzed before the final pump is installed. <br /> <br />Plan 2.--Develop water from the Smith Fork upstream <br />from the Iron Creek confluence. A small amount of <br />chemical testing indicates that the water improves <br />upstream. Several complete analyses should be made of <br />Smith Fork water at various points upstream from Crawford <br />to determine whether the water meets Public Health <br />Service standards. Development of these supplies would <br />entail obtaining water rights and construction of diversion <br />and storage facilities. <br /> <br />plan 3.--Develop springs in Gunnison National Forest. <br />This will require construction of collection facilities <br />in a relatively remote area and a pipeline (several miles <br />10nW to the recreation area. If suitable arrangements <br />can be made with the owners of existing spring-water <br />systems, the Park Service might tap these systems rela- <br />tively close to the recreation area. The town of Crawford <br />has a spring-water reservoir about a mile north of the <br />recreation area. The cathedral Water Association has <br />plans for construction of a pipeline to carry spring water <br />to the vicinity of the recreation area. <br /> <br />14 <br />
