The Colorado River Aqueduct
Fact Sheet: Our Water Lifeline__ The Colorado River Aqueduct. Photo: Aerial photo of CRA Investment in Reliability The Colorado River Aqueduct is considered one of the nation’s Many innovations came from this period in time, including the top civil engineering marvels. It was originally conceived by creation of a medical system for contract workers that would William Mulholland and designed by Metropolitan’s first Chief become the forerunner for the prepaid healthcare plan offered Engineer Frank Weymouth after consideration of more than by Kaiser Permanente. 50 routes. The 242-mile CRA carries water from Lake Havasu to the system’s terminal reservoir at Lake Mathews in Riverside. This reservoir’s location was selected because it is situated at the upper end of Metropolitan’s service area and its elevation of nearly 1,400 feet allows water to flow by gravity to the majority of our service area The CRA was the largest public works project built in Southern California during the Great Depression. Overwhelming voter approval in 1929 for a $220 million bond – equivalent to a $3.75 billion investment today – brought jobs to 35,000 people. Miners, engineers, surveyors, cooks and more came to build Colorado River the aqueduct, living in the harshest of desert conditions and Aqueduct ultimately constructing 150 miles of canals, siphons, conduits and pipelines. They added five pumping plants to lift water over mountains so deliveries could then flow west by gravity. And they blasted 90-plus miles of tunnels, including a waterway under Mount San Jacinto.

Although there is plenty of rooa tor 1 aproveaent in praotice through better under standing or the probleaa involved and apec 1rically through greater care in preparation of aaterials , the industry undoubtedly is here to stay and haa aade only a start ln ita developaent. The Departaent hal had a working interest in the developaent of li ghtweight aggregates. Ita work hal been along both geological and engineering lineo in encouraging tho industry'o growth and it ie hoped that loae Departaental proJects now under way will be of further alsiet �ce. The author ot thie paper, Kr. Ralph s. Mason, has done field and laboratory work on ao a t or the aateriala now used as lightweight aggre gates or a• building atones. He has prepared Jointly with Kr.

BRITISH MINING No.37 BRITISH MINING No.37 MEMOIRS 1988 Bird, R.H. 1988 “Notes on Mining Leats” British Mining No.37, NMRS, pp.19-45 Published by the THE NORTHERN MINE RESEARCH SOCIETY SHEFFIELD U.K. © N.M.R.S. & The Author(s) 1988. ISSN 0309-2199 NOTES ON MINING LEATS R.H. Bird “.... the means of putting to work many mines that would otherwise remain unworked, or if worked, could not be worked with profitable results.” Absalom Francis. 1874. SYNOPSIS Watercourses supplying mining works have been in use for centuries but their complexity increased during the 19th century, particularly in mining districts which were remote from coal supplies used for steam engines but which had sufficient river systems (or streams) of a dependable nature. Their role in Britain’s mining areas is discussed, with examples from overseas locations. An attempt is made to outline their construction methods and costs. In an age when water power reigned supreme and, indeed, for some time thereafter, mills and manufacturing industries were dependant on a steady supply of water to drive that prime mover, the water wheel. Flour mills, fulling mills and the early ferrous metal industries were sited next to reliable river or stream courses and could thus utilise this water source with little difficulty. Sometimes, the configuration of the stream was inconveniently placed for the mill site and the miller was forced to construct a ditch, from a dam upstream of his mill, and by this, lead the water to his wheel. After driving the wheel, the water was returned to the stream directly or through another ditch, the tailrace. -

Syn-eruptive incision of Koko Crater, Oahu, Hawaii by condensed steam and hot cohesive debris flows: a re-interpretation of the type locality of “surge-eroded U-shaped channels” by Jessica Keri Bluth B.S., State University of New York at Binghamton, 2001 Submitted to the Graduate Faculty of Arts and Sciences in partial fulfillment of the requirements for the degree of Master of Science University of Pittsburgh 2004 UNIVERSITY OF PITTSBURGH FACULTY OF ARTS AND SCIENCES This dissertation was presented by Jessica Keri Bluth It was defended on June 25, 2004 and approved by Dr. Michael Ramsey Dr. Charles Jones Dr. Ian Skilling Committee Chairperson ii Syn-eruptive incision of Koko Crater, Oahu by condensed steam and hot cohesive debris flows: a re-interpretation of the type locality of “surge-eroded U-shaped channels” Jessica K. Bluth, M.S. Department of Geology and Planetary Science University of Pittsburgh, 2004 Phreatomagmatic fall, low-concentration PDC deposits and remobilized equivalents dominate the products of craters (tuff cones/rings) of Koko fissure, south-east Oahu. At Koko crater, Fisher (1977) described “U-shaped” channels, which he interpreted as due to erosion by low-concentration PDCs (surges), with minor modification by stream and debris flows. Similar channels on tuff cones and rings elsewhere in the world have been interpreted as “surge-eroded” by subsequent authors. However, no evidence for erosion by PDCs was observed during recent fieldwork, which suggested rather the following model. An important observation is that initial incision is always correlated with the emplacement of vesiculated ash layers (derived from Hanauma Bay), and is only very rarely associated with other facies.
