UDALL, Secretary GEOLOGICAL SURVEY Thomas B. Nolan, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington 25, D.C. PREFACE This report on the floods of December 1955-January 1956 in the Far Western States was prepared by the U.S. Geological Survey, Water Resources Division. C. G. Paulsen, chief hydraulic engineer, suc­ ceeded by Luna B. Leopold, under the general direction of J. V. B. Wells, chief, Surface Water Branch. A preliminary report of peak discharges was released as Geological Survey Circular 380 in August 1956. Basic records of stage and discharge in the area, covered by Water- Supply Paper 1650-B, were collected by the U.S. Geological Survey as part of a continuous program in cooperation with the States of California, Idaho, Oregon, Nevada, and Washington; county and city agencies within these states; and agencies of the Federal Government. The records of stage and discharge were collected and computed under the direction of the following district engineers: California, R. C. Briggs, succeeded by R. S. Lord; Idaho, T. R. Newell; Oregon, K. N. Phillips; Nevada, M. T. Wilson; Washington, F. M. Veatch. The report was assembled and the text prepared under the general supervision of Tate Dalrymple, chief, Floods Section, Surface Water Branch. G. L. Bodhaine, Flood Specialist, contributed to the section on previous floods and coordinated the work of the Oregon, Idaho, and Washington district offices. The help of various district personnel in preparing the text is also acknowledged. in CONTENTS Page Abstract______________________________________________________ A 1

    National Humanities Center Resource Toolbox The Making of African American Identity: Vol. III, 1917-1968 Black Belt Press The ONTGOMERY BUS BOYCOTT M and the WOMEN WHO STARTED IT __________________________ The Memoir of Jo Ann Gibson Robinson __________________________ Mrs. Jo Ann Gibson Robinson Black women in Montgomery, Alabama, unlocked a remarkable spirit in their city in late 1955. Sick of segregated public transportation, these women decided to wield their financial power against the city bus system and, led by Jo Ann Gibson Robinson (1912-1992), convinced Montgomery's African Americans to stop using public transportation. Robinson was born in Georgia and attended the segregated schools of Macon. After graduating from Fort Valley State College, she taught school in Macon and eventually went on to earn an M.A. in English at Atlanta University. In 1949 she took a faculty position at Alabama State College in Mont- gomery. There she joined the Women's Political Council. When a Montgomery bus driver insulted her, she vowed to end racial seating on the city's buses. Using her position as president of the Council, she mounted a boycott. She remained active in the civil rights movement in Montgomery until she left that city in 1960. Her story illustrates how the desire on the part of individuals to resist oppression — once *it is organized, led, and aimed at a specific goal — can be transformed into a mass movement. Mrs. T. M. Glass Ch. 2: The Boycott Begins n Friday morning, December 2, 1955, a goodly number of Mont- gomery’s black clergymen happened to be meeting at the Hilliard O Chapel A.

History is replete with instances where, even in the light of obvious and flagrant macroeconomics disequilibria, the implementation of stabilization programs is significantly delayed. Why do policymakers and/or politicians prefer to live with growing inflationary pressures and implement price and other forms of highly inefficient con- trols instead of tackling the roots of macroeconomic imbalances? Is the prolongation of inflation the consequence of mistaken views on the me- chanics of fiscal deficits and money creation, or is it the unavoidable result of the political game? Why, after months of apparent political stalemate, are stabilization programs all of a sudden adopted that closely resemble others proposed earlier? These questions are at the heart of the political economy of stabilization and inflationary finance.1 In recent years the analysis of these issues has attained new interest, as a number of authors have applied the tools of game theory to the study of macroeconomic pol- icymaking.

Center for Ecosystem Management and Restoration CONTRA COSTA COUNTY Marsh Creek Watershed Marsh Creek flows approximately 30 miles from the eastern slopes of Mt. Diablo to Suisun Bay in the northern San Francisco Estuary. Its watershed consists of about 100 square miles. The headwaters of Marsh Creek consist of numerous small, intermittent and perennial tributaries within the Black Hills. The creek drains to the northwest before abruptly turning east near Marsh Creek Springs. From Marsh Creek Springs, Marsh Creek flows in an easterly direction entering Marsh Creek Reservoir, constructed in the 1960s. The creek is largely channelized in the lower watershed, and includes a drop structure near the city of Brentwood that appears to be a complete passage barrier. Marsh Creek enters the Big Break area of the Sacramento-San Joaquin River Delta northeast of the city of Oakley. Marsh Creek No salmonids were observed by DFG during an April 1942 visual survey of Marsh Creek at two locations: 0.25 miles upstream from the mouth in a tidal reach, and in close proximity to a bridge four miles east of Byron (Curtis 1942).

  • Ethnohistory and Ethnogeography of the Coast Miwok and Their Neighbors, 1783-1840
    ETHNOHISTORY AND ETHNOGEOGRAPHY OF THE COAST MIWOK AND THEIR NEIGHBORS, 1783-1840 by Randall Milliken Technical Paper presented to: National Park Service, Golden Gate NRA Cultural Resources and Museum Management Division Building 101, Fort Mason San Francisco, California Prepared by: Archaeological/Historical Consultants 609 Aileen Street Oakland, California 94609 June 2009 MANAGEMENT SUMMARY This report documents the locations of Spanish-contact period Coast Miwok regional and local communities in lands of present Marin and Sonoma counties, California. Furthermore, it documents previously unavailable information about those Coast Miwok communities as they struggled to survive and reform themselves within the context of the Franciscan missions between 1783 and 1840. Supplementary information is provided about neighboring Southern Pomo-speaking communities to the north during the same time period. The staff of the Golden Gate National Recreation Area (GGNRA) commissioned this study of the early native people of the Marin Peninsula upon recommendation from the report’s author. He had found that he was amassing a large amount of new information about the early Coast Miwoks at Mission Dolores in San Francisco while he was conducting a GGNRA-funded study of the Ramaytush Ohlone-speaking peoples of the San Francisco Peninsula. The original scope of work for this study called for the analysis and synthesis of sources identifying the Coast Miwok tribal communities that inhabited GGNRA parklands in Marin County prior to Spanish colonization. In addition, it asked for the documentation of cultural ties between those earlier native people and the members of the present-day community of Coast Miwok. The geographic area studied here reaches far to the north of GGNRA lands on the Marin Peninsula to encompass all lands inhabited by Coast Miwoks, as well as lands inhabited by Pomos who intermarried with them at Mission San Rafael.

  • San Mateo County Watershed Data in a GIS
    San Mateo County Watershed Data in a GIS Introduction The San Mateo Countywide Water Pollution Prevention Program (Program) performs Watershed Assessment and Monitoring (WAM) component activities in compliance with its municipal stormwater NPDES permit requirements. In the past, a consistent countywide watershed boundary data layer has not been available to meet Program needs for mapping and analyzing watershed-related data. As a result, the Program has previously utilized the best existing available data sets and/or developed new data to meet the objectives of specific individual projects. For example, creek location and watershed boundary data were developed to characterize imperviousness and channel modifications in seventeen watersheds in San Mateo County (STOPPP 2002). In another example, Program staff compiled existing countywide watershed data and developed new data needed to identify watershed areas considered exempt from Hydromodification Management Plan (HMP) requirements (STOPPP 2005). The Program previously identified two major information gaps in digital watershed boundary data: 1) limited storm drain catchment data were available for urban areas and 2) consistent countywide watershed data layers were not available (STOPPP 2005). Recent development of watershed data in urbanized portions of San Mateo County has provided an opportunity to address these information gaps. This memo describes the methods used by Program staff to create a consistent countywide watershed data layer that includes delineation of storm drain catchments in urban areas. Consistent watershed and creek data set will assist Program staff in watershed characterization and the identification and prioritization of potential future monitoring and watershed assessment activities. Background In 1999, the State of California developed a statewide watershed data layer entitled the California Interagency Watershed Map (Calwater).
