Leif,
A good study on the effects of a pumped storage project on fish 
populations was conducted for a project on the Susquehanna River 
during the 1970's.  The following publication presented the 
results of the study:

Robbins, T. W., and D. Mathur.  1976.  The Muddy Run Pumped 
Storage Project: a case study.  Transactions of the American 
Fisheries Society ?:165 - 172.

Since this study, I am sure several other projects have been 
assessed for ecological impacts.  The U.S. Corps of Engineers have 
probably conducted studies at some of its pumped storage projects, 
namely the Richard B. Russell and Harry S. Truman Projects.  Also, 
with many hydro projects undergoing licensing in the U.S., I am 
sure there have been many published studies that deal with the 
effects of peaking. I suggest you conduct a literature search if 
possible.

Is there anybody out there ho have done research on
pump storages and their effect on the fish community ?

Or have you done research on hydropower peaking and
the effect on fish ?

Please contact.

The Luddington Pumped storage project on Lake Michigan was studied for 
entrapment and entrainment back in the 1970's.
Pumped storage has the potentially severe impact of entrainment and 
entrapment due to high unnatural current velocity. This can be 
ameliorated by site-specific intake location and design.
Studies have also been done in many places on the impact of peaking 
discharges to downstream fish populations. Some of the impact depends on 
the type of discharge (surface or bottom) which can discharge warm or 
cold water or water low in oxygen (or high in nitrogen) which might be 
detrimental at particular times. Again this is often site-specific.
Badly designed intakes can kill large quantities of valuable game forage 
and commercial fish. eg. before the eel ladder went in on a hydraulic dam 
on the St. Lawrence R., at leat 16 tons of migratory  American eels were 
killed each year.
