| OWENS RIVER. - Rock Creek is a tributary of Owens River, and enters the same below the proposed power house site in Big Round Valley. The condition of the watershed, run-off, and all natural features of Owens River, are simply a repitition of the two streams above mentioned, and its average flow during the winter season is about 437 second feet, while the average flow during the floodsseason is equal to about 3500 second feet. It is well to mention in connection with Owens River that the water of said Owens River never freezes, even during the coldest winters, which peculiar feature is accounted for by numerous hot springs situated in the higher regions of Long Valley, and issuing many hundreds of second feet of water into Owens River, which river flows through the entire length of Long Valley. For all three rivers above mentioned, it is equally correct to state, that at head waters of these streams at very high elevations are numerous and large laXes, which could be utilized for reservoir sites, in addition to Long Valley, but which were not accessible at the time of the year I examined this proposition. LONG VALLEY, OR THE RESERVOIR SITE.- Long Valley is a large basin of about 38 miles in length and 6 miles in average width, surrounded by the high mountains of the Sierra Nevada, and having an outlet through a narrow gorge, called the Owens River Canon. This gorge is about 18 or 30 miles in length, and from 300 to 400 feet wide, and from 600 to 800 feet deep. This gorge is best compared with the Grand Canon of the Colorado, only not quite as deep 3
