and Environmental Impact Studies
our environmental assessment and impact studies include long-term monitoring
of migration patterns of rare and endangered
fishes in relation to water diversion and hydro-electric projects in
the deserts of Texas
and Nevada. We have also optimized draw-down rates of reservoirs to minimize fish mortality in Ontario
based on empirical and field observations. From 1996 to 1999 we investigated the effects of peaking hydroelectric operations on brown trout and brook trout in the Rocky Mountains, and
the effects of hydroelectric operations on eels in the St. Lawrence River.
In 2004 and 2005, we assisted the Cree Regional Authority, by reviewing and assessing
a large-scale Environmental Impact Statement produced by
Hydro Quebec in relation to significant river flow diversion
near James Bay.
other clients such as Stantec Ltd and Yellow Falls Power
Ltd. determine requirements for fish passage
at proposed hydroelectric generating stations and mines. In
2006 we assisted the City of London with permitting
requirements related to fish passage, and we collected
baseline fish movement data that was compared with post
construction fish movement at the Springbank dam. Some environmental assessments simply involve
biological studies, species inventories, mussel
relocations, identification of migratory pathways, and other behavioural
or physiological patterns of interest prior to, during or after major construction projects;
while others are more complicated. We specialize in the development of biological, self-sustaining solutions and strategies to reduce and minimize harmful effects
of dams and other instream projects on fish and other wildlife, while recognizing specific needs and requirements of our clients.
