Plan of Management for Spring Creek Reservoir
PLAN OF MANAGEMENT FOR SPRING CREEK RESERVOIR ORANGE CITY COUNCIL DATE OF ADOPTION: 3 December 2007 GENERAL MANAGER D07/15538 1. LAND COVERED UNDER THIS PLAN OF MANAGEMENT This Plan of Management applies to land comprising Spring Creek Reservoir as indicated on Map 1. Each parcel of land covered by this plan is detailed in Schedule 1 to the plan. 2. CATEGORY AND CLASSIFICATION OF LAND The land is classified as community land under the Local Government Act 1993 (“the Act”). The following community land categories apply to the land: • General Community Use • Natural Area - wetland The Natural Area category applies to that part of the dam and foreshores identified for the protection of bird habitats and breeding areas in the report prepared by Dr J Beard and Professor D Goldney in April 2000 to assess the potential for recreational activities on Spring Creek Reservoir as indicated in Map 2. 3. LAND OWNERSHIP The Land is owned by Orange City Council. 4. LOCATION & AREA The land comprises about 143.5 hectares of land adjacent to Lone Pine Avenue, Calton Road, Louie Lane and Shepherd Road in the locality of Summer Hill. The reservoir is located about 400 metres south of the edge of the Orange urban area defined by the Leewood Industrial Estate. 5. BACKGROUND Spring Creek Reservoir was constructed in 1931 at the confluence of the Gosling and Spring Creeks as the City’s third water supply reservoir after Gosling and Meadow Creek Reservoirs (Lake Canobolas). The reservoir was located downstream of Gosling Dam. The Spring Creek dam wall was raised in 1947 which increased the full supply level (FSL) by 1.8 metres. -

REPORT 1St Session HOUSE of REPRESENTATIVES 105–9 "!
105TH CONGRESS REPORT 1st Session HOUSE OF REPRESENTATIVES 105±9 "! DESIGNATION OF TRINITY LAKE, CALIFORNIA MARCH 10, 1997.ÐReferred to the House Calendar and ordered to be printed Mr. YOUNG of Alaska, from the Committee on Resources, submitted the following REPORT [To accompany H.R. 63] [Including cost estimate of the Congressional Budget Office] The Committee on Resources, to whom was referred the bill (H.R. 63) to designate the reservoir created by Trinity Dam in the Central Valley project, California, as ``Trinity Lake'', having consid- ered the same, report favorably thereon without amendment and recommend that the bill do pass. PURPOSE OF THE BILL The purpose of H.R. 63 is to designate the reservoir created by Trinity Dam in the Central Valley Project, California, as ``Trinity Lake''. BACKGROUND AND NEED FOR LEGISLATION H.R. 63 would designate the reservoir created by Trinity Dam in the Central Valley Project, California, as ``Trinity Lake.'' Under the provisions of P.L. 88±662, the reservoir is currently designated as ``Clair Engle Lake,'' and therefore requires legislation in order for the name to be changed. Trinity Dam and the reservoir on the Trinity River regulate a drainage area of over 728 square miles. Trinity Dam, completed in 1962, is an earthfill structure 538 feet high with a crest length of 2,450 feet. The reservoir has a maximum storage capacity of 2.448 million acre-feet of water. Releases from the reservoir are used to generate power at Trinity, Lewiston, Spring Creek, Judge Francis Carr, and Keswick powerplants, and for consumptive use in the Central Valley Project. -
A. INTRODUCTION the Devil's Basin Research Natural Area (DBRNA
A. INTRODUCTION The Devil's Basin Research Natural Area (DBRNA) lies within the Corning Ranger District, Mendocino National Forest (Maps 1 and 2). The California black oak (Quercus kelloggii1)stands and surrounding areas of Devil's Basin were first reconnoitered in 1984 (Henry 1984), and subsequently proposed as a representative of the California Black Oak Woodland type (Holland 1986). An ecological survey of the basin was completed in 1987 (Newton 1987). Unless otherwise noted, information contained in this Establishment Record is based on this ecological survey. The DBRNA has had no history of intensive use such as logging or grazing. The DBRNA is entirely under public ownership with the Mendocino National Forest. 1) Land Management Planning The establishment of Devil's Basin RNA is recommended and evaluated in the Mendocino National Forest Land and Resource Management Plan (LRMP 1995) and the Environmental Impact Statement and Appendices for the LRMP (U.S.D.A. Forest Service 1995a-c). The land allocation for the Devil's Basin RNA was decided by the signing of the Record of Decision (ROD) for the LRMP by the Regional Forester (1995). The establishment of the DBRNA is completed upon signature of this Establishment Record with concurrence of the Station Director. The area lies within the Research Natural Areas Management Area #5 allocated to Management Prescription #11 which emphasizes the preservation of natural conditions and the protection of features for which the RNA was established (Appendix 3). B. OBJECTIVES The primary purpose for establishment of the DBRNA is to preserve a representative of a Black Oak Woodland ecosystem and its associates in a condition minimally modified by humans within the North Coast Physiographic Province for their scientific value and educational importance. -

Seeking an Understanding of the Groundwater Aquifer Systems in the Northern Sacramento Valley
SEEKING AN UNDERSTANDING OF THE GROUNDWATER AQUIFER SYSTEMS IN THE NORTHERN SACRAMENTO VALLEY Allan Fulton1, Toccoy Dudley2, Kelly Staton2, Debbie Spangler2 SOUND CONCEPT OR MISCONCEPTION To many people, the Sacramento Valley appears as an expansive groundwater basin filled with freshwater. It is also common to conceptualize the groundwater basin as an underground lake or a series of underground rivers that provide water to wells. Are these sound concepts or misconceptions? Recent interpretation of over 150 down-hole electrical resistivity logs from widely scattered locations throughout much of the northern Sacramento Valley has revealed that these simplistic concepts are incorrect. This pamphlet provides a glimpse of ongoing studies of the aquifer systems in the northern Sacramento Valley. The findings are preliminary and will likely improve as further information is gathered. Comprehensive reports of these studies should be available later in 2004. KNOWLEDGE GAPS AND NEW INVESTIGATIONS Concepts are easily formed and rationalized and can appear to be factual without sufficient field research to validate them. Until recently, only three regional investigations of the aquifer systems in the Sacramento Valley had been completed in the past 80 years and none were conducted since the mid 1970’s. Since 1997, the California Department of Water Resources, Northern District, Groundwater Section, headquartered in Red Bluff, California, has been conducting new investigations into the saline and freshwater aquifer systems in the northern Sacramento Valley. Findings from their investigations offer a greater understanding of the geology and hydrogeology in the northern Sacramento Valley. METHODS USED IN RECENT GROUNDWATER INVESTIGATIONS Geologic cross-sections have been and are currently being developed to help understand the sub-surface hydrogeology of the northern Sacramento Valley. -

Mathias Kondolf Principal Investigator and w.v. Graham Matthews Research Associate Center for Environmental Design Research University of California Berkeley CA 94720 TECHNICAL COMPLETION REPORT ,.\. Project No. UCAL-WRC-W-748 December 1991 University of California Water Resources Center The research leading to this report was supported by the University of California, water Resources Center, as part of Water Resources Center Project UCAL-WRC-W-748. :TCR / Abstract There are significant problems in the management of coarse sediment (sand and gravels) in regulated rivers of California. Unfortunately, these have been generally treated (or ignored) on a case-by-case basis, however, the effects are pervasive and profound, with substantial costs and severe environmental impacts. Problems arise due to the human manipulation of coarse sediment through reservoir construction, which blocks the movement of coarse sediment down the river, and through instream gravel mining, which removes this material from the river system for use primarily in construction-related projects. Impacts identified include: bed material coarsening, channel incision, channel geometry changes, hydrologic regime alterations, and changes in transport of sediment. Many of these impacts result in damage to or destruction of anadromous fisheries habitat, and are partly responsible for the dramatic declines in anadromous fisheries resources in the last 50 years. -
