The Saugeen Ojibway Nation (SON) was honoured in mid-June by
the Fantastic Lakes Fishery Commission (GLFC) for its element in controlling sea
lamprey in Lake Huron.

Chief Lester Anoquot of the Saugeen Initial Nation
(represented by Head Councillor Conrad Ritchie), Chief Gregory Nadjiwon of the
Chippewas of Nawash, Mr. Doran Ritchie, manager of sources and infrastructure
for SON, and Ms. Kathleen Ryan, Saugeen Ojibway’s power manager, had been presented
with the C.C. “Buzz” Besadny Award for Fostering Fantastic Lakes Partnerships
through the commission’s annual meeting. The award was for function carried out on Denny’s
Dam on the Saugeen River.

Dam constructed as barrier

The dam, which spans the river 1.five kilometres from Lake
Huron, was constructed in 1970 as a lamprey barrier. Positioned north of Port Elgin,
it is a well-liked fishing spot.

“It required to be rehabilitated and we saw the will need to get in
there for the reason that if it wasn’t carried out with lamprey in thoughts, lamprey would get in
upstream,” stated Dr. Marc Gaden of the GLFC.

GLFC Commissioner Tracey Mill stated, “The rehabilitation of
Denny’s Dam was produced doable by a shared understanding among the Commission
and the SON that efforts to strategy, style, engineer, construct, and monitor the
project would respect the SON’s aboriginal and treaty rights. The collaboration
formed a basis of expertise, trust, and a ‘sleeves-rolled-up’ atmosphere exactly where
everybody was operating ‘on the ground’ and difficulties could be straight away raised and
thoughtfully addressed.”

Structure got facelift

The dam was dewatered, the face rebuilt, the concrete shored
up, and a lip place at the prime of the dam.

Gaden stated the dam is blocking 100 kilometres of prospective lamprey habitat. If lamprey had been to invade the Saugeen, estimates are it could make 30,000 per year. That is important, thinking of Lake Huron’s total lamprey population is 70,000. The price to treat the river with lampricide is estimated at $600,000.
