Members of the Hat Creek Watershed Technical Advisory Committee include: 5California Regional Water Quality Control Board (RWQCB) 5WM Beaty & Associates 5Fall River Resource Conservation District (FRRCD) 5Pit River Tribe 5Sierra Pacific Industries 5Northeastern California Water Association (NECWA) 5United States Forest Service, Hat Creek Ranger District 5Fall River Wild Trout Foundation 5Central Modoc River Center 5United States Forest Service (USFS), Lassen National Forest (Hat Creek Ranger District) 5Pacific Gas & Electric (PG&E) 5California Department of Fish and Game (CDFG) 5Burney Chamber of Commerce 5State of California Parks and Recreation Division 5Fall River Conservancy In addition, the Sierra Institute for Community and the Environment – working on a grant from the Shasta County Resource Advisory Committee (RAC) – collaborated with the FRRCD on this assessment. Much of the initial scoping work completed for the assessment was augmented and expanded by the work of the Sierra Institute on their project. Our thanks. WHAT IS A WATERSHED ASSESSMENT? A watershed assessment is a method used to understand a watershed. It is a process for evaluating how well a watershed is functioning. Watershed assessments may include identifying important issues, examining historic conditions, evaluating present conditions and processes, and determining the effects of human activities. It can mean describing the parts and processes of the whole watershed and analyzing their functioning in general, or relative to some standard (such as a water quality standard or historic condition). It also can mean focusing on particular concerns about human activities, conditions, or processes in the watershed. Watersheds by their nature are fluid and complex, making it difficult to fully understand their processes and conditions. Understanding watersheds in California is all the more challenging due to the state’s exceptionally diverse array of geographic and hydrologic conditions, which is overlain by an equally diverse set of social and economic conditions. The amount of data available about these conditions varies greatly from watershed to watershed, which adds to difficulty in understanding the watershed condition (Shilling, et al, 2005). INTRODUCTION The primary purpose of the Hat Creek Watershed Assessment (WA) and Watershed Management Plan (WMP) is to serve as a guide for the development of ecosystem improvements for the Hat Creek Watershed. This document was developed using available data, previous work by others, and other information available to the FRRCD. The WA/WMP identifies seven goals, management objectives for those goals, and management actions to achieve the goals and objectives. 1 HAT CREEK WATERSHED ASSESSMENT & Fall River Resource Conservation District WATERSHED MANAGEMENT PLAN The WMP discusses the primary issues and concerns for the watershed that have been developed by the FRRCD and Sierra Institute working under a separate RAC grant. The plan provides management recommendations for projects and other actions to address those concerns. The purpose of the WA/WMP is to: 5Define conditions limiting or threatening watershed health 5Define actions needed to address conditions that are currently limiting or threatening watershed health 5Facilitate a better understanding of causes that are limiting or threatening those conditions 5Identify lead stakeholders for implementing management actions 5Identify information needs in the watershed 5Provide a framework for periodic evaluation of management results, reformulation of management approaches, and identification of new watershed management issues 5Support the maintenance and improvement of desired landscape conditions in the watershed (e.g. sustainable agricultural operations, open space, quality wildlife habitat) The six goals discussed in this WA/WMP are: 1. Support community sustainability by strengthening natural-resource-based economies 2. Maintain high-quality water in Hat Creek 3. Maintain and improve forest health and vigor 4. Maintain availability of water in the system for irrigation demands and ecological needs 5. Maintain and improve habitat quality for indigenous cold water fish 6. Support and encourage better coordination of data collection, sharing, and reporting in the watershed HAT CREEK WATERSHED ASSESSMENT The Hat Creek Watershed is located in northeastern California in Shasta and Lassen Counties. Hat Creek flows north through the watershed and drains into the Pit River. The Hat Creek Watershed includes approximately 243,000 acres with 250 stream miles. Elevation in the watershed varies from 10457 feet above mean sea level at the Lassen Peak summit, located in the southern portion of the watershed, to the confluence with the Pit River at 2800 feet above mean sea level. The largely volcanic history of the region has done much to shape the topography and landforms present today. The watershed boundary is shown on Figure 1. Elevation bands are shown on Figure 2. Hydrology in the watershed is shown on Figure 3. The Hat Creek Watershed is known for its cool, clear water and blue-ribbon wild trout. The watershed is in healthy condition today, with the exception of fuel-loading on USFS land. As long as landowners continue to keep the working landscapes in the watershed viable, and economic conditions and landscape uses improve, the health of the watershed will be maintained for years to come. 2 Fall !River Mills UV89 Hat Creek Val ley UV299 Brush Mountain Burney !
