The five stations ~e Boustead <br />Tunnel outlet and North Cunningham, Middle Cunningham, Chapnan GulCh, <br />and Ivanlxle Creeks.

Turq=ise Lake <br /> <br />. <br /> <br />On Septanber 30, 1980, 90,170 acre-feet of water was in storage in <br />Turquoise Lake., Of this total, 22,990 acre-feet wa5 owned by CF&I <br />Steel Corporation, with the ranainder belol'Bing to the Fryingpan-Arkansas <br />Project ani other entities rontracting for project storage space. <br /> <br />The project stored 23,230 acre-feet of water for the Hanestake Project <br />for regulation in Turquoise Lake. <br /> <br />Approximately 6 ft3/s of project water has been oontinually releaseCI <br />into the Mt. Elber-t Conduit, then tiu:Ough the Federal Fish Hatchery near <br />Leadville to enhance their operation. <br /> <br />On September 30, 1981, 90,00D acre-feet of water was in storage in <br />Turqooise Lake.

Elbert Fbrebay <br /> <br />The project assumed the operation of Twin Lakes on Jnne 1, 1981. !ioI>1=ver, <br />prior to the actual takeover, regulation of project water was being done <br />by exchange so that the testing of Mt. Elbert Pumped-Storage Powerplant <br />might be accomplished. <br /> <br />. <br /> <br />Due to seepage in excess of that anticipated at the new Twin Lakes Darn, <br />a study was initiated. On April 9 the drawdown of water fran betw2en <br />the old darn and the new dam was started. The evacuation was made in <br />stages so that the seepage rate at varying elevations rould be observed. <br />By Jnne 17 the water between the darns was =npletely evacuated and <br />remained that way through September 30. <br /> <br />9 <br />
