The Fault Line Threatening Dams
The Fault Line Threatening Dams The Fault Line Threatening Dams Deficient structures, earthquake risks raise possibility of potentially catastrophic flooding By Jim Carlton June 24, 2017 FREMONT, Calif.-The coastal mountains that frame this working-class city next to San Francisco Bay harbor a hidden menace: a reservoir 10 miles away that sits next to an active earthquake fault, which experts say could cause a dam break and flood thousands of homes. The potential threat is so severe, the owner of the Calaveras Reservoir decided to build a replacement dam. But seven years after that work began, the dam is unfinished and isn't expected to be complete until 2019 -- four years behind schedule. The issues hampering the Calaveras Reservoir project show how difficult it can be to repair or replace an old dam, which is of growing concern nationally. An estimated 27,380 dams, or 30% of the 90,580 listed in the latest 2016 National Inventory of Dams, are rated as posing a high or significant hazard. Of those, more than 2,170 are considered deficient and in need of upgrading, according to a report by the American Society of Civil Engineers. The inventory by the U.S. Army Corps of Engineers doesn't break out which ones are deficient. But funding and inspection staffing are considered inadequate, the civil engineers' report said. An estimated $64 billion is needed to upgrade those dams, including $22 billion for those posing the highest hazard, according to the Association of State Dam Safety Officials, a nonprofit group in Lexington, Ky. "It's a huge problem with limited resources," said Ivan Wong, a consulting seismologist from Walnut Creek, Calif., who works on dam projects nationally.

CALIFORNIA FISH and GAME ' CONSERVATION of WILDLIFE THROUGH EDUCATION'
REPRINT FROM CALIFORNIA FISH and GAME ' CONSERVATION OF WILDLIFE THROUGH EDUCATION' . VOLUME 50 APRIL 1964 NUMBER 2 ANNUAL ABUNDANCE OF YOUNG STRIPED BASS, ROCCUS SAXATILIS, IN THE SACRAMENTO- SAN JOAQUIN DELTA, CALIFORNIA' HAROLD K. CHADWICK Inland Fisheries Branch California Department of Fish and Game INTRODUCTION A reliable index of striped bass spawning success would serve two important management purposes. First, it would enable us to determine if recruitment is directly related to spawning success. If it is, we could predict important changes in the fishery three years in advance. Second, it would give insight into environmental factors responsible for good and poor year-classes. Besides increasing our understanding of the bass population, this knowledge might be used to improve recruit- ment by modifying water development plans in the Sacramento-San Joaquin Delta under the State Water Resources Development System. Fyke net samples provided the earliest information on young bass distribution (Hatton, 1940). They were not promising for estimating abundance, and subsequent sampling of eggs and larvae with plankton nets also had important limitations (Calhoun and Woodhull, 1948; Cal- houn, Woodhull, and Johnson, 1950). An exploratory survey with tow nets in the early summer of 1947 (Calhoun and Woodhull, 1948) found bass about an inch long dis- tributed throughout the lower Sacramento-San Joaquin River system except in the Sacramento River above Isleton. This suggested the best index of spawning success would be the abundance of bass about an inch long, measured by tow netting. In 1948 and 1949 extensive tow net surveys were made to measure the relative abundance of young bass in the Delta between Rio Vista and Pittsburg (Erkkila et al., 1950).

Appendix D Building Descriptions and Climate Zones
Appendix D Building Descriptions and Climate Zones APPENDIX D: Building Descriptions The purpose of the Building Descriptions is to assist the user in selecting an appropriate type of building when using the Air Conditioning estimating tools. The selected building type should be the one that most closely matches the actual project. These summaries provide the user with the inputs for the typical buildings. Minor variations from these inputs will occur based on differences in building vintage and climate zone. The Building Descriptions are referenced from the 2004-2005 Database for Energy Efficiency Resources (DEER) Update Study. It should be noted that the user is required to provide certain inputs for the user’s specific building (e.g. actual conditioned area, city, operating hours, economy cycle, new AC system and new AC system efficiency). The remaining inputs are approximations of the building and are deemed acceptable to the user. If none of the typical building models are determined to be a fair approximation then the user has the option to use the Custom Building approach. The Custom Building option instructs the user how to initiate the Engage Software. The Engage Software is a stand-alone, DOE2 based modeling program.

Calaveras Dam Fact Sheet Bcj 091511 V2.Indd
Calaveras Dam Replacement Services of San Francisco Fact Sheet Public Utilities Commission www.sfwater.org/sunolvalleywww.sfwater.org/ulistac 866-973-1476 Calaveras Reservoir Project Summary The San Francisco Public Utilities Commission, operator of the Hetch Hetchy Regional Water System, is rebuilding Calaveras Dam, our largest local Bay Area drinking water reservoir. The existing earth ﬁ ll dam is located near the active Calaveras earthquake fault. We lowered water levels in the reservoir in response to seismic concerns in 2001. The project will construct a new dam equal in height next to the existing seismically-vulnerable dam so that the historic capacity of the reservoir can be restored. The new Calaveras Dam will be one of only a few major dams built in the State of California in the last 30 years. The $416 million project breaks ground in September 2011. The Calaveras Dam Replacement Project is the largest project among the 81 projects of our $4.6B Water System Improvement Program. The Hetch Hetchy Regional Water System delivers drinking water to 2.5 million Bay Area customers. Construction Began: August 2011 Projected Completion: August 2015 Total Project Cost: $416 Million Construction Contractor: Joint Venture of Dragados USA, Flatiron Construction, and Sukut Construction Project Details The project consists of building a new zoned earth and rock ﬁ ll dam immediately downstream of the existing dam. This work will restore the Calaveras Reservoir to its historic capacity. The reservoir provides approximately half of the Hetch Hetchy Regional Water System’s local Bay Area water storage. This storage is crucial to providing adequate water to our customers in times of drought and when Sierra Nevada resources are not available.

Abundance and Distribution of Shorebirds in the San Francisco Bay Area
WESTERN BIRDS Volume 33, Number 2, 2002 ABUNDANCE AND DISTRIBUTION OF SHOREBIRDS IN THE SAN FRANCISCO BAY AREA LYNNE E. STENZEL, CATHERINE M. HICKEY, JANET E. KJELMYR, and GARY W. PAGE, Point ReyesBird Observatory,4990 ShorelineHighway, Stinson Beach, California 94970 ABSTRACT: On 13 comprehensivecensuses of the San Francisco-SanPablo Bay estuaryand associatedwetlands we counted325,000-396,000 shorebirds (Charadrii)from mid-Augustto mid-September(fall) and in November(early winter), 225,000 from late Januaryto February(late winter); and 589,000-932,000 in late April (spring).Twenty-three of the 38 speciesoccurred on all fall, earlywinter, and springcounts. Median counts in one or moreseasons exceeded 10,000 for 10 of the 23 species,were 1,000-10,000 for 4 of the species,and were less than 1,000 for 9 of the species.On risingtides, while tidal fiats were exposed,those fiats held the majorityof individualsof 12 speciesgroups (encompassing 19 species);salt ponds usuallyheld the majorityof 5 speciesgroups (encompassing 7 species); 1 specieswas primarilyon tidal fiatsand in other wetlandtypes. Most speciesgroups tended to concentratein greaterproportion, relative to the extent of tidal fiat, either in the geographiccenter of the estuaryor in the southernregions of the bay. Shorebirds' densitiesvaried among 14 divisionsof the unvegetatedtidal fiats. Most species groups occurredconsistently in higherdensities in someareas than in others;however, most tidalfiats held relativelyhigh densitiesfor at leastone speciesgroup in at leastone season.Areas supportingthe highesttotal shorebirddensities were also the ones supportinghighest total shorebird biomass, another measure of overallshorebird use. Tidalfiats distinguished most frequenfiy by highdensities or biomasswere on the east sideof centralSan FranciscoBay andadjacent to the activesalt ponds on the eastand southshores of southSan FranciscoBay and alongthe Napa River,which flowsinto San Pablo Bay.
