<br /> <br />Glossary <br /> <br />@ <br /> <br />water in its natural course or location by means of a ditch, canal, flume, reservoir, <br />bypass, pipeline, conduit, well, pump or other device. <br /> <br />Division Engineer: subordinate officers under the State Engineer; Division <br />Engineers perform the functions of the State Engineer-administering water rights-in <br />each of Colorado's seven water divisions. The Gunnison watershed is in Division 4. <br /> <br />Due Diligence: the requirement for holders of conditional water rights to <br />demonstrate to the water court that they are making good faith efforts toward con- <br />structing the facilities (e.g., ditch, reservoir, etc.) to apply the water right within a rea- <br />sonable time. In Colorado, conditional water right holders must show due diligence <br />to the water court every six years. <br /> <br />EHluent: liquid attributed to human waste, Le., sewage, arising from various <br />uses of water; also often refers to water discharged after use, such as water leaving a <br />wastewater treatment plant or industrial plant. <br /> <br />Exchange: a process by which water rights in one part of a river (or other <br />water supply) system are traded for the use of water rights in another part of the river <br />system. <br /> <br />Firm Annual Yield: The yearly amount of water that can be dependably sup- <br />plied from the raw water sources of a water supply system. <br /> <br />Fish Ladder: an inclined water channel structure with a series of baffles or <br />weirs that helps fish gain upstream passage around dams. These baffles interrupt and <br />slow the flow of water, simulating pools and rapids. Fish swim up the ladder just as <br />they would swim up natural rapids. <br /> <br />Giga-Watt Hour (GWh): a measurement that represents one thousand mil- <br />lion watts used in an hour. <br /> <br />Ground Water: water found below the eartb's surface. <br /> <br />Headgate: a human-made structure on a stream, canal, or other water chan- <br />nel through which water is diverted into a ditch or canal. <br /> <br />Headgate Management: see ':-\dministration." <br /> <br />Hydrograph: a graph showing the seasonal flow pattern of a river at a given <br />point along its course; usually measured in cubic feet per second (efs). <br /> <br />Instream Flows: water left in its natural stream channel to maintain the <br />existing aquatic resources and associated wildlife and riparian habitat. In contrast to <br />out-of-stream uses, this kind of water use does not require diversion. <br /> <br />Lower Colorado River Basin: the Colorado River and its tributaries in <br /> <br />Gunnison Basin Water <br /> <br />.55. <br />
