The Town holds water rights that provide for the diver- <br /> <br />sion of a maximum of 7.00 c.f.s. from Beaver Creek and 0.178 c.f.s. from the <br /> <br />springs. The water is diverted from Beaver Creek about €ix miles south of <br /> <br />Ridgway in an open ditch (Ridgway Ditch) which also intercepts flows from the <br /> <br />springs within the first mile of its general northerly course. From the Beaver <br /> <br />Creek diversion the ditch extends along mountainous terrain for about four <br /> <br />miles, and crosses into the drainage basin of Cottonwood Creek, a small inter- <br /> <br />mittent tributary of the Uncompahgre River. From the terminus of the ditch at <br /> <br />Lake. Otonawanda, the water flows down Cottonwood Creek for about two miles to <br /> <br />where it is diverted into a buried pipeline of 8" and 6" diameter pipe that <br /> <br />extends about one-half mile to three small open earth reservoirs that are used <br /> <br />as storage and as settling basins. <br /> <br />The water is not filtered but is chlorinated as it leaves the reservoirs <br /> <br />and enters a 6" diameter buried pipeline that leads to the town's distribution <br /> <br />system. The distribution system consists of an estimated 24,000 feet of buried <br /> <br />steel and cast iron pipe ranging from 6" to ':!" in diameter. Water usage is not <br /> <br />metered. <br /> <br />Although the water is generally of high quality at the sources, contamina- <br /> <br />tion, consisting principally of suspended organic and inorganic materials occurs, <br /> <br />ii <br />
