Fish Migration Infrastructure at the Vianney-Legendre Dam
MILIEU was given the mandate by
Parks Canada to design, construct, and install an eel ladder at the
Saint-Ours Dam located on the Richelieu River. MILIEU monitored the
passage of eels at the the eel ladder for three years. Furthermore,
MILIEU worked at the
new multi-species facility to optimize its operation.

more Design and Construction of a Seasonal Lamprey Barrier
MILIEU managed the design, construction, and installation of a
flow-through screen barrier on the Morpions Stream. The previously
unimpeded Morpions Stream provides a large spawning and rearing habitat
for Sea Lampreys, who
have a sizable impact on the Lake Champlain ecosystem.

more Smolt survival at the Mitis Dam, Quebec
The survival of smolts going
through the Mitis-1 Power Dam was assessed by MILIEU. The smolts were
tagged, released into the turbine and collected downstream.
Learn
more Lake Sturgeon reproduction in western Lake St. Louis
The Lake Sturgeon is a closely
watched species because of its precarious status and its historical
importance to the commercial fishing industry. MILIEU conducted a study
to determine if the west of Lake St. Louis was used by
sturgeon as a spawning ground.
