THE FEATHER RIVER COORDINATED RESOURCE MANAGEMENT GROUP RED CLOVER CREEK
DEMONSTRATION
PROJECT

Fact Sheet # 3 March 1996

FIRST PROJECT

In 1985, erosion problems in the Feather River water-shed prompted an alliance of local, state, and federal agen-cies and landowners to organize themselves into the Feather River Coordinated Management group (CRM). CRM group members decided to conduct a small demonstration project in the head waters of the Feather River wa-tershed as a first step toward coordination of erosion control efforts across the entire watershed. Goals for the demonstration project were to test whether erosion control techniques would be effective at stabilizing stream banks, slowing sediment production and improving water quality. They also hoped to develop a cooperative process among supporting organizations that could be used on future projects.

PROJECT LOCATION

The demonstration project is located on a one mile stretch of Red Clover Creek, a tributary of Indian Creek, which feeds into the the East Branch of the North Fork of the Feather River (EBNFFR). The creek flows through Red Clover Valley, a highly credible alluvial valley at an elevation of 5,400 feet in Plumas County, California, 30 miles Northeast of Quincy. The valley, which is six miles long and two miles wide, is privately owned and used for grazing cattle while the surrounding sparsely forested pub-lic land is administered by the Plumas National Forest.
Near the project area. Red Clover Creek flows in a mean-dering channel up to 50-60 feet wide and 10 feet deep, with bare and eroding vertical banks.

SITE HISTORY

Red Clover Creek has down cut it's channel severely over time due to both natural processes and intensive land use. The amount of vegetation and number of plant species found along the creek has declined dramatically since the turn of the century. Before 1880, Red Clover Creek was a narrow stable channel with vegetation, including hardwood trees, willows, and grasses, growing along it's banks. Increased land use and disturbance since that time has produced a drier, less vegetated site which is vulnerable to large floods and erosion. Timber harvesting, mining, railroad and road construction, and grazing have acted together to cause the decline.

Unmanaged grazing can lead to stream degradation when cattle consume and trample plants leaving stream banks bare of protective vegetation. Without this plant cover, the stream's banks erode more quickly during storms. Bank erosion leads to widening and deepening of the channel over time. The deeper channel drains the lands adjacent to the creek more quickly. The shallow water table across the flood plain lowers, drying out plants and soils. Fewer plant species can survive under these drier conditions which allow sage brush to replace the more desirable willow, sedges and grasses. This reduces the area's suitability for grazing by livestock and wildlife. The silt produced by eroding banks also clogs the stream and covers spawning gravels, making it less suitable for fish habitat.

PROJECT PLANNING

The Red Clover Creek Demonstration Project was conceived to attempt to reverse the stream's decline. Planning of the project started in August of 1985. A team of agency resource experts surveyed the site and then a study plan was developed by the Feather River CRM Steering Committee. The project site is on a privately owned ranch, while the control area is on land administered by the USFS.

The Feather River CRM group agreed on the following project objectives:
* Stabilize the stream banks to reduce erosion and sedi-ment transport downstream, and
* Raise the ground water table and water storage capacity to restore meadow habitat and moisture.
It was anticipated that meeting these objectives would also increase range forage quantity and quality, improve water quality, and fish and wildlife habitat.

PROJECT DESIGN

The Red Clover Creek Demonstration Project com-bined building in-stream structures with revegetation and grazing exclusion. The design consisted of:
* Construction of four loose rock check dams 
Dams were built across the creek to reduce water speed, trap sediment, stabilize stream banks, and induce groundwater infiltration. Dams also created ponds to raise the adjacent water table out into the meadow and increase water storage.
* Stream bank stabilization and revegetation 
Banks were planted with native moist site species including aspen, alder, willow and grasses to restore and stabilize areas disturbed by dam construction. Banks were then lined with small cut pine trees to protect bare soil and slow water to encourage stream bank building and vegetation growth.
* Fencing of the riparian corridor 
One mile of stream was fenced creating a 70 acre enclosure. Fencing excluded livestock and vehicle traffic from the project area to encourage growth of vegetation and minimize erosion.
* Monitoring of results
Project results were monitored for 10 years assessing effects on water table level, water storage, vegetation recovery, fish habitat, water quality, and wildlife use. Information was collected after construction both on site and in a downstream section of the creek which served as a control area.
  Check dam construction was completed in Spring 1986, while revegetation was finished by Spring 1987.

PROJECT MONITORING

Feather River CRM members agreed to monitor the project to evaluate its success at reversing stream degrada-tion, stabilizing stream banks and raising the water table. They also wanted to know whether physical changes in the stream positively affected vegetation, fish and wildlife abundance and water quality. Analysis of ten years of monitoring data has documented the following results:

STREAM CHANNEL SHAPE & STABILITY:
Check dams successfully reduced the velocity of stream flow, which allowed sediments to deposit along stream banks, causing the channel to narrow and become more sinuous. Sloughing of vertical stream banks slowed due to successful revegetation and bank reinforcement.
   Channel improvements also oc-curred in the project's control area due to changes in grazing manage-ment. The channel dramatically nar-rowed and stream bank vegetation began to reestablish without the help of check dams, but at a slower pace. This implies that changes in grazing management alone may provide channel benefits at a lower cost than intensive restoration efforts when changes aren't needed quickly and land management changes can be sustained over a long-period.

GROUND WATER LEVELS:
The elevation of the groundwater table was significantly increased in the vicinity of the check dams com-pared to control areas, contributing

to meadow recharge and the rapid growth of riparian and flood-plain vegetation, which helped stabilize soils and vegetation in the project area.
PLANT SPECIES DIVERSITY & DENSITY:
The number of plant species and density of vegetation cover along stream banks and in the adjacent meadow increased as the water table elevation increased. There was a clear trend from sagebrush to more desirable riparian meadow vegetation.
FISH AND WILDLIFE POPULATION:
Average populations of adult trout increased greatly but re-production did not increase because no spawning or rearing habitat was created. Waterfowl usage and nesting increased 700% over the control site and deer use greatly increased. Neotropical migrant birds are now using the site and the short-eared owl, a state listed species of special concern, reproduced there. Meadow vole populations increased in step with the increasing trend to moist meadow plant species.
APPEARANCE:
Stream channel shape and vegetation was tracked using photographs taken at 13 permanent photo points. Photos, such as those shown at the right, show the healing process from raw stream banks into well vegetated banks.
COOPERATIVE PROCESS:
The Coordinated Resources Management organizational framework was successful for project coordination. The CRM process was retained and used in an additional 19 projects be-tween 1985 and 1995. (See Fact Sheet #l for a description of this process and Fact Sheet #2 for a list of projects.)

"Red Clover Creek Demonstration Project created an oasis of high quality wetland-riparian habitat in an .area where there was little before. Using both rock check dams to raise the ground water table and , fencing to exclude grazing led to faster vegetation recovery than could have happened using only one of these stream restoration techniques."
(Department of Water Resourses, 1993)
