1.0 INTRODUCTION AND PURPOSE
This Public Safety Plan (PSP) for the Bucks Creek Project, Federal Energy Regulatory
Commission (FERC) No. P-619 (Project), explains how Pacific Gas & Electric Company
(PG&E) will meet the requirements of 18 Code of Federal Regulations (CFR) 12.52, which
requires PG&E to “install, operate, and maintain any signs, lights, sirens, barriers, or other
safety devices that may reasonably be necessary or desirable to warn the public of
fluctuations in flow from the project or otherwise to protect the public in the use of the
project lands and waters.”
This PSP identifies the proper safety signage and safety measures that are in place to
inform the public of potential hazards and to help mitigate any potential injury to those
who use project lands and waters. This PSP also identifies operational procedures used to
protect the public, for example, using an on-site operator to check downstream before
opening a spillway gate and specifying when boat barriers are installed and removed.
This PSP addresses potential hazards created by Project structures and operations. The
various recreational areas that are operated by PG&E are included to address proper
safety measures. This PSP contains topographic maps or Google Earth images of the site
locations that identify the safety measure present at each location.

2.0 GENERAL PROJECT DESCRIPTION
The Project is divided into two developments: Bucks Creek Development and Grizzly
Development. The areas that have public safety features are described below generally
following the flow of water through each development.
Flow from Bucks Lake is released and immediately flows into a short reach of Bucks Creek
before emptying into Lower Bucks Lake. The Milk Ranch Conduit conveys flow from Three
Lakes Reservoir and small intervening tributary diversions to Lower Bucks Lake. Water
from Lower Bucks Lake travels through the Grizzly Powerhouse Tunnel to Grizzly
Powerhouse and discharges into Grizzly Forebay. Instream flow releases are made from
Lower Bucks Lake into Bucks Creek. Water from Grizzly Forebay travels through the Grizzly
Forebay Tunnel to the Bucks Creek Powerhouse and discharges into the Rock Creek Reach
of the North Fork Feather River upstream of Cresta Reservoir.

3.0 PROJECT RECREATION RESOURCES AND FACILITIES
Notable recreational resources where the Project is located include six river reaches, six
travel corridors, and 12 lakes and reservoirs. Most of the land in this region of California
is public land managed by the United States Forest Service (USFS). The Project’s primary
recreation facilities and opportunities are focused around Bucks Lake and Lower Bucks
Lake.
3.1 BUCKS CREEK DEVELOPMENT
3.1.1 Three Lake Reservoir
Three Lakes is about 6 air-miles north of Bucks Lake and is accessed via Three Lakes Road
(Forest Road 24N24). Three Lakes Road, a narrow and winding 13-mile long, single-lane,
four-wheel drive road, originates at Lower Bucks Lake. These reservoirs are entirely located
on National Forest System Land (NFSL) with the two most eastern reservoirs extending
into Bucks Lake Wilderness. At normal maximum water surface elevation, the 44-acre
water surface of the reservoirs provides a setting for primitive recreational activities and
the 2-mile shoreline has no development.
3.1.2 Bucks Lake Reservoir
Bucks Lake is located about 17 miles west of Quincy along the Oroville-Quincy Highway
(also known as Bucks Lake Road). This route is typically open during the summer months
after the road is plowed for snow removal. Plumas County does not maintain (plow) the
road through the winter season.
The majority of the shoreline consists of NFSL land managed by the Plumas National
Forest (PNF). The eastern shoreline (about a quarter of the entire shoreline) abuts Bucks
Lake Wilderness Area and is undeveloped, except for the Mill Creek Trail that provides
access into the wilderness. PG&E owns land along the southern shore and around Haskins
Bay where there are recreational residences, commercial resorts (with boat launches), and
a public campground (with boat launch). PG&E’s day-use facilities include West End Cove
and Indian Rocks, which includes picnic units, single vault restroom, and single-vehicle
parking spaces. The Shoreline Management Plan (SMP) specifies a 25-foot horizontal
setback from the ordinary high-water mark for buildings and development (except docks
and buoys).
Recreational developments at Bucks Lake that provide public access to the reservoir and
shoreline include campgrounds (family and group), day use areas, and boat launches that
are located on NFSL and PG&E land. The majority of recreational use occurs during the
summer when visitors enjoy water sports, fishing, swimming, camping, and picnicking.
Commercial resorts at the reservoir provide lodging, cabin rentals, groceries, restaurants,
Document Accession #: 20250708-5142 Filed Date: 07/08/2025
December 2024 3-2 Kleinschmidt
Project Control No. 0836016.06
boat rentals, and gasoline. In addition, privately owned cabins and docks are located on
NFSL and PG&E lands that are authorized under the terms of special use permits from the
USFS or leases from PG&E, respectively. The recreational facilities at Bucks Lake are
typically open for public use during the summer from Memorial Day weekend through
Labor Day weekend.
3.1.3 Lower Bucks Lake
This reservoir is downstream of and adjacent to Bucks Lake Dam. The developed
recreational facilities and the area at Lower Bucks Lake are only accessible during the
summer months because the access road is not plowed for snow removal during the
winter. The shoreline, other than two recreation facilities, is undeveloped. At the Lower
Bucks Lake area, the campgrounds available to the public are owned and managed by the
USFS.
3.1.4 Grizzly Forebay
Grizzly Forebay is located on NFSL about 5 miles west of Bucks Lake and is accessed via
the Bucks Penstock Road, a gravel road, and the Grizzly Forebay Road, which is an asphalt
road. Recreation vehicles and trailered vehicles are not allowed on this road. The reservoir
has steep canyon walls and steep, forested shorelines providing a natural setting for
recreational activities. Grizzly Forebay is only accessible during the summer months
because the access road is not plowed for snow removal during the winter.
Grizzly Forebay access area has a single vault restroom, a car-top launch, and single-
vehicle parking spaces. From the parking area, the Grizzly Forebay Trail extends along the
northern shore of the forebay providing access to the walk-in/boat-in Grizzly Forebay
Campground. The campground is 0.75 mile from the parking area along the trail; the trail
extends another 0.5 mile beyond the campground, to the forebay inlet. In addition, the
Grizzly Forebay Gauging Station Trail also originates from the forebay parking area and
continues about 0.3 mile downstream to the stream gauging station below the dam. The
trails are not recommended for horses and OHV use is prohibited. The access area and
campground are typically open from Memorial Day weekend through Labor Day
weekend.
