<br />r"l <br /> <br />. <br /> <br />senior-right.--A relative term referring to a right with an earlier priority. <br />See "junior right,'1 <br /> <br />shrink.--A local term used to describe the decrease of an entity's water <br />supply by anyone of a number of causes. It has been used in reference to: <br />(1) The transportation loss charged in routing a reservoir release down a <br />river channel; (2) the pro-rata share from the participants of the Pueblo <br />Reservoir Winter Water Program (see discussion under Fryingpan-Arkansas <br />Project; to provide the agreed share to an entity not receiving a full share; <br />and (3) the decrease of reservoir-storage accounts by evaporation. <br /> <br />slick water_--A local term used to describe high flow from the Apishapa River <br />into the Arkansas River. Because of the large concentration of sediment in <br />Apishapa flood flows, the water is undesirable for irrigation, and, when pos- <br />sible, is not diverted. <br /> <br />sluice.--As used most commonly in the Arkansas River valley in Colorado, this <br />local term refers to the act of washing sand and other sediments from canals <br />back into the stream from which they were diverted. Host canals are equipped <br />with one or more sluice gates along their length, one almost always just down- <br />ditch from the headgate, and up ditch from the measuring section. <br /> <br />sluice box.--ln placer mining, a long inclined trough paved with riffles for <br />catching gold from water-borne gravel washed through the passage. <br /> <br />. <br /> <br />storage.--".. .the impoundment, possession, and control of water by means of a <br />dam...'l (Radosevich and others, 1975). To retain possession of stored waters <br />requires a storage right (storage decree). <br /> <br />storage right.--See water right. A storage right allows the holder to store a <br />given volume of water .each year for beneficial use later in the season or in <br />following seasons. <br /> <br />surcharge.--See reservoir-storage allocation. <br /> <br />tailwater.--Excess surface water draining from an irriated field or returning <br />to natural channels from the downgradient end of an irrigation ditch. It also <br />is the water in a channel immediately downstream from a dam, mill, or power- <br />plant. <br /> <br />transit loss.--Colorado water law allows the.owner of a reservoir to use a <br />natural stream to convey stored water to the place of use, provided that <br />allowance is made for losses that occur while the water is in the natural <br />stream. The State Engineer has the responsibility of determining these losses <br />(Luckey and Livingston, 1975). <br /> <br />. <br /> <br />transmountain diversions.--The importation of water originating in one river <br />basin from that basin into another river basin. The diversion is by means of <br />a ditch, canal, or conduit through a topographic saddle in the divide between <br />the basins, or by means of a tunnel through the basin divide. A water right <br />is required in the basin from which the diversion is made, and a record of <br />imports is made at the outlet end of the conveyance structure in the receiving <br />basin. <br /> <br />xi <br /> <br />.;J4.; j <br />~. <br />.....- <br />
