SUBJECT: Experimental Acoustical Fish Barrier Field Research

The following two reports and a summary paper are now available from the
sources shown after the citations.  These reports cover ongoing work on the
Georgianna Slough Experimental Acoustical Fish Barrier placed in the
Sacramento River of California (USA).

Behavioral barrier testing at Georgianna Slough is designed and conducted as
a cooperative research and development project among a variety of State and
Federal resource agencies, and water districts.  Primary coordination for
the demonstration project was through the Interagency Ecological Program's
(IEP) New Fish Facilities Development Project Work Team, which includes
participation by the Ca. St. Dept. of  Fish & Game (DFG), U.S. Fish and
Wildlife Service (USFWS), U.S. Bureau of Reclamation (USBR), and Ca. St.
Dept. of Water Resources (DWR).  The San Luis & Delta-Mendota Water
Authority administered Phase I and II of the project under contract to DWR
and USBR, with field support from Hanson Environmental.  Phase III and IV
were the direct responsibility of DWR, with contracted support from Hanson
Environmental, the DFG, and other IEP agencies.

SUMMARY PAPER:
The following summary paper is derived from Hanson Environmental, Inc. 1993
and 1996, and preliminary data from Hanson, et. al. 1997, In preparation.
Since the latter report has yet to receive formal interagency review
mandated by IEP procedures, interpretations of the results of Phase III and
IV studies can only be considered preliminary and subject to change upon
completion of the required review process.

If you are a researcher with any experience in the evaluation of behavioral
fish guidance devices (sound, light, electricity), please contact Kevan
Urquhart with any published or unpublished information you may have on the
subject.  I would appreciate hearing from you.  If you have a professional
interest in the development of behavioral barriers for fish guidance, and
are willing to voluntarily participate in our interagency peer review
process for future study plans and reports, please let me know this also,
and I will submit your name to the IEP Project Leader, Mr. Darryl Hayes.
