In 2008, San Mateo Co. Farm Bureau (Farm Bureau) was approached by RedTree
Properties, a timberland property owner in the Redwood forested area in San Mateo
County to work with them to remove a 100 year old, 12 foot high Log Dam in Waterman
Creek, a tributary to Pescadero Creek in San Mateo County. This dam has been a
complete barrier to steelhead migration for a century. Removal or reduction of this dam
would provide access to over a 1 ½ miles of spawning habitat to this threatened fish.
Stream restoration projects are typically expensive and difficult to permit. RedTree
Property and their timber manager (active participants in the Pescadero/Butano
Agricultural Watershed Working Group) asked Farm Bureau to help.

                             Waterman Dam prior to Phase One

This project proposed a staged reduction of dam height over a two to three year period.
A crew of three journeymen loggers, using chainsaws with carbon chains cut through the
24” diameter logs which comprise the dam. A choker cable is attached to the logs which
are slid up to the landing area near a D-7 which is parked outside of the riparian area. It
is expected that the stream will discharge some of the upstream bed load into the
sediment “starved” bedrock pools below.

This “low tech” construction approach to stream restoration is novel to San Mateo
County. The suggested project management and administration is also a change to the
standard protocol. This project is administered and managed by the Farm Bureau through
our Conservation and Water Quality Program. The construction and in-field construction
management is done by the timber manager and operators working with RedTree
Properties. This proposal is also attractive because the cost of this dam removal, using
these methods, is extremely cost effective.
After discussion with the Calif Dept of Fish and Game and NOAA Fisheries, a grant
proposal was written by Farm Bureau which was accepted and funded by American
Rivers, a non profit corporation partner of the NOAA Restoration Center. The local
Native Sons of the Golden West Parlor (Pebble Beach #230) from Pescadero joined as a
partner, offering a cash “match” from their “steelhead fund” to help with up-front permit

Staff members from several agencies cooperated in this project and are monitoring the
site as the dam is reduced in height and the upstream trapped sediment is “metering out”.

All of the necessary permits were acquired and Phase One of the project commenced in
October 2008. During this phase, the top 4.5’ of the dam was removed.

                             Waterman Dam after Phase One.

Phase Two occurred in October 2009 (on schedule) and reduced the height of the dam
another 3 ½ feet. The project will be monitored over the Winter and Spring of 2010. A
final phase may occur in October 2010 if warranted.

This collaboration of Farm Bureau, landowner and State and Federal Agencies has been a
great success. It has achieved the goals of the landowner (active forest
management/timber harvest together with a land and water conservation ethic) while
assisting State and Federal Agencies recover steelhead populations on the San Mateo Co.

This “co-management” success can be used as a model for future projects.
