THE YOSEMITE by John Muir CHAPTER I The
THE YOSEMITE By John Muir CHAPTER I The Approach to the Valley When I set out on the long excursion that finally led to California I wandered afoot and alone, from Indiana to the Gulf of Mexico, with a plant-press on my back, holding a generally southward course, like the birds when they are going from summer to winter. From the west coast of Florida I crossed the gulf to Cuba, enjoyed the rich tropical flora there for a few months, intending to go thence to the north end of South America, make my way through the woods to the headwaters of the Amazon, and float down that grand river to the ocean. But I was unable to find a ship bound for South America--fortunately perhaps, for I had incredibly little money for so long a trip and had not yet fully recovered from a fever caught in the Florida swamps. Therefore I decided to visit California for a year or two to see its wonderful flora and the famous Yosemite Valley. All the world was before me and every day was a holiday, so it did not seem important to which one of the world's wildernesses I first should wander. Arriving by the Panama steamer, I stopped one day in San Francisco and then inquired for the nearest way out of town. "But where do you want to go?" asked the man to whom I had applied for this important information. "To any place that is wild," I said. This reply startled him. He seemed to fear I might be crazy and therefore the sooner I was out of town the better, so he directed me to the Oakland ferry.

Mineral Resources of the Emigrant Basin Primitive Area, California
Mineral Resources of the Emigrant Basin Primitive Area, California By E. W. TOOKER, H. T. MORRIS, U.S. GEOLOGICAL SURVEY, and PAUL V. FILLO, U.S. BUREAU OF MINES With a section on GEOPHYSICAL STUDIES By H. W. OLIVER, U.S. GEOLOGICAL SURVEY STUDIES RELATED TO WILDERNESS PRIMITIVE AREAS GEOLOGICAL SURVEY BULLETIN 1261-G An evaluation of the mineral potential of a part of the central Sierra Nevada UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1970 UNITED STATES DEPARTMENT OF THE INTERIOR WALTER J. HICKEL, Secretary GEOLOGICAL SURVEY William T. Pecora, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 In accordance with the provisions of the Wilderness Act (Public Law 88-577, Sept. 3,1964) and the Conference Report on Senate bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines are making mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe," when the act was passed were incorporated into the National Wilderness Preservation System. Areas classed as "primi tive" were not included in the Wilderness System, but the act provides that each primitive area should be studied for its suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This bulletin reports the results of a mineral survey in the Emigrant Basin primitive area, California. The area discussed in the report corresponds to the area under consideration for wilderness status. It is not identical with the original Emigrant Basin Primi tive Area as defined because modifications of the bound ary have been proposed for the area to be considered for wilderness status.

Introduction
Introduction On May 18, 2004, the Board of Supervisors adopted a motion directing the Budget Analyst to perform a management audit of the Public Utilities Commission (Motion No. M04-57). As explained below, this report is the result of the second phase of a four- phase management audit. Our first phase management audit report on the Clean Water Enterprise was issued on September 27, 2004. Purpose and Scope The purpose of this management audit is to evaluate the economy, efficiency, and effectiveness of the Public Utilities Commission’s programs, activities, and functions, and the Public Utilities Commission’s compliance with applicable State and Federal laws, local ordinances, and City policies and procedures. This management audit is conducted in four phases: • The Phase I Management Audit of the Public Utilities Commission – Clean Water Enterprise Fund report was submitted to the Board of Supervisors on September 27, 2004. • Phase II, which is the subject of this report, is a review of the Hetch Hetchy Enterprise’s programs, activities and functions. • Phase III is a review of the Water Enterprise Fund’s programs, activities, and functions, including water supply, treatment, and distribution for regional and City customers. • Phase IV is a review of the programs, activities, and functions of the Public Utilities Commission as a whole, including the Water System Capital Improvement Program, administrative functions, and enterprise functions, such as asset management, that affect all three enterprise funds. This Phase II report reviews the Hetch Hetchy Enterprise in terms of: • Business planning and risk management processes. • Implementation of analytical software. • Maintenance and operations functions.

The Battle for the Tuolumne
Modesto Irrigation District The Power To Grow Greening of Paradise Valley - The First 100 Years of the Modesto Irrigation District Chapter 11 The Battle for the Tuolumne One of the most divisive and fascinating chapters in the history of the Modesto Irrigation District was precipitated by the determination of the City and County of San Francisco to tap the Tuolumne River for its domestic water supply. Although in later years the three entities – the Modesto and Turlock Irrigation Districts and the City of San Francisco – were to work together developing the Tuolumne’s resources, both districts at first were “unalterably opposed” to San Francisco being on the river. The bitter early fights were to generate recall elections in the MID, split the Modesto and Turlock districts in a manner that for some time threatened further cooperation in the development of the original Don Pedro Reservoir, and generated intense emotions among the people. Long before the great 1906 San Francisco earthquake and fire proved that city’s water supply to be tragically inadequate, San Francisco was looking to the Sierra for water. In 1882 the San Francisco and Tuolumne Water Company of Sonora had proposed carrying Tuolumne River water to San Francisco from Jacksonville, a community flooded nearly a century later by the construction of New Don Pedro Reservoir. In 1888 two years before Yosemite National Park was created, George M. Harris stressed the value of the Hetch Hetchy Valley as a reservoir site and offered all his rights on the Tuolumne River, including title to his lands in Hetch Hetchy Valley, for $200,000.

I Integrated Water Operations in California: Hydropower, Overdraft
Integrated Water Operations in California: Hydropower, Overdraft, and Climate Change By MUSTAFA SAHIN DOGAN B.S. (Dokuz Eylul University, Izmir, Turkey) 2011 THESIS Submitted in partial satisfaction of the requirements for the degree of MASTER OF SCIENCE in Civil and Environmental Engineering in the OFFICE OF GRADUATE STUDIES of the UNIVERSITY OF CALIFORNIA DAVIS Approved: _____________________________________ Jay R. Lund, Chair _____________________________________ Samuel Sandoval Solis _____________________________________ Jonathan Herman Committee in Charge 2015 i Abstract Several management and climate cases are evaluated with the updated CALVIN, a hydro-economic optimization model of California’s inter-tied water supply infrastructure. Updates to the CALVIN model include new projected 2050 agricultural target demands and scarcity penalties, improvements to network- flow representation, especially agricultural, urban, and wildlife refuge demands, and extended surface and ground water hydrology, now covering an 82-year historical inflow hydrology. A new energy price scheme is applied to CALVIN, which incorporates hourly energy price variations into monthly CALVIN operations. Using one constant average price for a month underestimates hydropower revenue and overestimates pumping costs. Hourly-varying moving average prices improved representation of hydropower revenue without creating significant scarcities to agricultural and urban water users. Effects of ending long-term groundwater overdraft in the Central Valley are evaluated with several management cases using CALVIN. The cases include effects of Delta outflow and Delta exports from a “no overdraft” policy. The least cost overdraft that minimizes groundwater pumping and scarcity costs is calculated for the 82- year period. Prohibiting Delta exports result in severe water scarcities south of the Delta. Water operations are more economical when overdraft is ended with adaptations, such as more Delta exports, increased groundwater banking, and water trades, than historical operations with overdraft.
