The country through which the Pit River flows lies in the northernpart of California in the counties of Modoc, Lassen, Siskiyou, and basin seems to be of volcanic structure of comparatively recentorigin, the porous nature of the rocks allowing the precipitation to beabsorbed and stored in subterranean caverns from which it emergesthrough the medium of the various springs and streams which go tomake up the Fall and Pit Rivers. The feature of these streams whichmakes them so desirable for the purpose of developing hydro-electricenergy is their exceptional uniformity of How. For a period of observa-tion extending over several years, the minimum flow observed on the. JABULtTION OF PIAHT5 iu- aw* M.\P AND PROFILE. PIT RIVEK DEVELOPMENT Pit River was 2010 second feet, while the maximum was 13,300 secondfeet, or only times the minimum flow. On the Fall River the figuresshow an even more remarkal)le condition. Here the minimum flow ob-served was 1170 second feet, with a maximum of 1750, or about l\/-itimes the minimum. These figures speak for themselves, and are mutelyindicative of the truly remarkal)le supply of water suitable for hydro-electric development with which California is blessed. There follows a brief description of each of the three projects whichhave been completed, and of the transmission line and condenser stationwhich were found necessary in order that the power generated might betransmitted to the ultimate consumers in the San Francisco Bay Region. Hat Creek No. 1 At this plant, diversion is effected by means of a timber and rock-filled crib dam located on Hat Creek in the vicinity of Cassel
