Draft Lake Mendocino Master Plan Master Plan Draft Lake Mendocino Master Plan MendocinoMaster County, CaliforniaPlan U.S. Army Corps of Engineers San Francisco District Revised 2019 Page Intentionally Blank APPROVAL I have reviewed this Master Plan and Environmental Assessment for Lake Mendocino and Coyote Valley Dam for the guidance of future development for recreation and environmental stewardship efforts within the Lake Mendocino Project located near the City of Ukiah, Mendocino County, California. This Master Plan is technically sound, environmentally acceptable, and is in compliance with ER/EP 1130-2-550, Project Operations, Recreation Operations and Maintenance Policies. Therefore, I approve this Master Plan for the Lake Mendocino and Coyote Valley Dam Project, subject to updates as needed for the benefit of flood risk management, public use, and environmental stewardship. __________________________ __________________________ Date Travis J. Rayfield Lieutenant Colonel Commander, San Francisco District i Draft Lake Mendocino April 2019 Master Plan Executive Summary The Lake Mendocino Master Plan (Master Plan) provides the U.S. Army Corps of Engineers (USACE) a vision and direction to manage Lake Mendocino and its resources. The original Master Plan for Lake Mendocino was approved in 1959 and last updated in 1977, and serves as the guiding document for USACE responsibilities to preserve, conserve, restore, maintain, manage, and develop these project lands and associated resources. This revision to the 1977 Master Plan and the associated Environmental Assessment (EA) describe the existing conditions at Lake Mendocino and identify recreational opportunities and measures to preserve and protect natural and cultural resources. The Master Plan also outlines developmental needs, analyzes special problems, and provides guidance on public use, water quality, invasive species, natural areas, and historic properties within the USACE project boundaries. The Master Plan and EA provide a synopsis of the history of the area and recreational development of Lake Mendocino. This Master Plan presents a comprehensive inventory of natural, cultural, and recreational resources; land use classifications to guide future management; modernization of existing park facilities; resource objectives for each management unit; and an evaluation of existing and future needs required to provide a balanced management plan to improve outdoor recreation opportunities and sustain natural resources. The Master Plan makes recommendations for future improvements to Lake Mendocino’s facilities based on the land use classifications. It provides guidance to balance recreation opportunities, flood risk management, and the preservation of natural and cultural resources for current and future generations. Public participation is an important aspect of the development of the Master Plan. Public scoping meetings were held in the City of Ukiah in February 2018 to kick off the Master Plan process. The purpose of the public meetings was to provide information to the public on the USACE master planning process and to identify the changes and improvements the public would desire to see in the future at Lake Mendocino. Coordination with Tribal partners was also part of the Master Plan development process. Following internal USACE reviews, the Master Plan and EA will be made available for a final public review under the National Environmental Policy Act (NEPA), and official NEPA public meetings will be held before the plan is finalized. ii Draft Lake Mendocino April 2019 Master Plan TABLE OF CONTENTS Chapter 1 – Introduction 1 1.1 Project Authorization 1 1.2 Project Purpose 1 1.3 Watershed and Project Location 2 1.4 Purpose of the Master Plan 2 1.5 Master Plan History and REvision 3 1.6 Applicable Laws and Policy Guidance 6 Chapter 2 – Project Setting and Factors Influencing Resource Management and Development 10 2.1 Lake Mendocino Access 10 2.2 Description of the Reservoir 10 2.3 Hydrology (Surface Water, Ground Water) 12 2.4 Water Quality 12 2.5 Topography, Geology, Soils, and Seismicity 13 2.6 Climate 21 2.7 Fish and Wildlife Resources 24 2.8 Vegetation 27 2.9 Cultural Resources 34 2.10 Demographics and Economics 36 2.10 Recreation Facilities, Activities, and Needs 39 2.11 Real Estate 42 Chapter 3 – Resource Objectives 44 3.1 Goals and Objectives 44 Chapter 4 – Land Allocation, Land Classification, Water Surface, and Project Easement Lands 53 4.1 Land Allocation. 53 4.2 Land Classification. 53 Chapter 5 – Resource Plan 59 5.0 Resource Plan 59 5.1 Management Unit #1 – Lake Mendocino 61 5.2 Management Unit #2 – Dam Operations, Dam, Control Tower, Spillway 63 5.3 Management Unit #3 – Pomo Cultural Center 68 iii Draft Lake Mendocino April 2019 Master Plan 5.4 Management Unit #4 – Unique Wildflower Area 71 5.5 Management Unit #5 – Winery Point 78 5.6 Management Unit #6 – Sho-da-kai Recreation Area 82 5.7 Management Unit #7 – Chekaka Recreation Area 84 5.8 Management Unit #8 – Pomo Recreation Area 92 5.9 Management Unit # 9 – Kyen Campground/Oak Grove Day Use Area/North Boat Ramp 95 5.10 Management Unit # 10 – Miti Recreation Area 98 5.12 Management Unit # 12 – Bushay Campground/Mesa Day Use Area 104 5.13 Management Unit # 13 – Bill Townsend Fish Hatchery 108 5.14 Management Unit # 14 – Disc Golf Course 110 5.15 Management Unit # 15 – Project Administrative Buildings 112 Chapter 6 – Special Topics/Issues/Considerations 113 Chapter 7 – Agency and Public Coordination 114 Chapter 8 – Summary and Recommendations 117 8.1 Summary Overview 117 8.2 Land Classifications 117 8.3 Recommendation 118 8.4 Using the Master Plan 122 8.5 Updating the Master Plan 123 8.6 Including Others in the Master Planning Process 123 Chapter 9 – Bibliography 125 iv Draft Lake Mendocino April 2019 Master Plan FIGURES Figure 1.

O. Box 250 Potter Valley, CA 95469 A HISTORY OF THE SALMONID DECLINE IN THE RUSSIAN RIVER A Cooperative Project Sponsored By Sonoma County Water Agency California State Coastal Conservancy Steiner Environmental Consulting Prepared by Steiner Environmental Consulting P.O. Box 250 Potter Valley, CA 95469 August 1996 (707) 743-1815 (707) 743-1816 f«x [email protected] EXECUTIVE SUMMARY BACKGROUND Introduction This report gathers together the best available information to provide the historical and current status of chinook salmon, coho salmon, pink salmon, and steelhead in the Russian River basin. Although the historical records are limited, all sources depict a river system where the once dominant salmonids have declined dramatically. The last 150 years of human activities have transformed the Russian River basin into a watershed heavily altered by agriculture and urban development. Flows in the main river channel river are heavily regulated. The result is a river system with significantly compromised biological functions. The anthropogenic factors contributing to the decline of salmonids are discussed. Study Area The 1,485 square mile Russian River watershed, roughly 80 miles long and 10 to 30 miles wide, lies in Mendocino, Sonoma, and Lake counties. The basin topography is characterized by a sequence of northwest/southeast trending fault-block ridges and alluvial valleys. Lying within a region of Mediterranean climate, the watershed is divided into a fog-influenced coastal region and an interior region of hot, dry summers.

Chapman, Secretary GEOLOGICAL SURVEY W. E. Wrather, Director WASHINGTON, D. C. Free on application to the Director, Geological Survey, Washington 26, D. C. INDEX OF SURFACE-WATER RECORDS PART 11.PPACIFIC SLOPE BASINS IN CALIFORNIA TO SEPTEMBER 30, 1948 EXPLANATION The index lists the stream-flow ana reservoir stations in the Pacific Slope Basins in California for which records have been or are to be pub­ lished for periods prior to September 30, 1948. The stations are listed in downstream order. Tributary streams are indicated by indention. Station names are given in their most recently published forms. Paren­ theses around part of a station name indicate that the enclosed word or words were used in an earlier published name of the station or in a name under which records were published by some agency other than the Geological Survey. The drainage areas, in square miles, are the latest figures published or otherwise available at this time. Drainage areas that were obviously inconsistent with other drainage areas on the same stream have been omitted. Some drainage areas not published by the Geological Survey are listed with an appropriate footnote stating the published source of the figure of drainage area. Under "period of record" breaks of less than a 12-month period are not shown. A dash not followed immediately by a closing date shows that the station was in operation on September 30, 1948.
