A visit to the new
Chatsworth hatchery

We turned west from the highway
between Willamsford and Chatsworth and then south on the old gravel road
running parallel to #6 highway. It seemed much the same as it was on my
first visit 36 years ago. The road is still narrow, crowded by trees and
almost hidden between surrounding hills. Since much of the land along the
road is owned by the Ministry of Natural Resources, no new homes interrupt
the tree line and except for the maple trees being considerably higher,
I could have been back in 1966. Southern Ontario’s rural areas have changed
so much in just the last ten years that it is unusual to find an area almost
unchanged by time. Soon after we passed through the gate leading to the
old hatchery location the memories evaporated as newer buildings came in
sight. The date was January 18 this year and my companion and guide to
the new $6.5 million Chatsworth Fish Culture Station was Jeff Graham, president
of the engineering consultant firm of Henderson and Paddon. H& P is
responsible for the design and construction supervision of the big Grey
County fishery project that will double the old worn-out hatchery’s capacity
without requiring additional personnel.
Jeff gave me a good tour
through all sections of the building and we were accompanied by Manager
John Sager, H&P Site Inspector Art Smith and Jamie Hastings from Allen
Hastings Construction.
The auxiliary rooms are products
of modern fish culture design ideas and include three quarantine rooms
that will contain fish strains not yet proven to be free of disease. These
rooms have sealed non-slip floors that can be easily disinfected and remind
me of nuclear fuel-handling facilities at the Bruce Power Station. The
water and effluent from these rooms is settled, clarified, chlorinated
and de-chlorinated before being released into the nearby upper Sydenham
River.
In the main building there
are 34 large concrete fish-holding tanks from 12-15 meters long and approximately
2.4 meters wide. In addition there are 16 large fiberglass-reinforced plastic
tanks. The depth of water in these tanks will be 1.2 meters or about 4
feet deep.
The station’s location in
Grey County and its real value is based on a first class water supply from
a free-flowing spring source providing about 14,000 liters per minute all
year. H&P have incorporated this gravity-fed supply so that it flows
un-pumped from the source on MNR property through an aeration system (ground
water does not contain enough dissolved oxygen for fish) then downhill
to the building and through three banks or levels of fish tanks installed
downstream from each other.
All water supply main piping
inside the building is solvent-welded schedule 40 PVC varying from 100
to 600 mm in diameter but the main water supply is delivered through 750
mm diameter piping to prevent head loss.
Isolation valves are conveniently
located so operators can drain one tank or several as required. There are
access doors which allow a fork lift or other vehicle to deliver fish food
and pick up fish for delivery to stocking locations.
The building itself was pre-engineered
by Dura Buildings and is fully insulated between double walls and double
ceiling panels. Heating is not required as the un-varying ground water
temperature alone should keep the building comfortable all year.
The opening of the new station
is planned for this spring after all testing is completed and Chatsworth
staff will then transfer the present lake trout brood stock and their progeny
fingerlings to their new homes. About 95% of the station’s output is slated
for Lake Huron and Manager John Sager assured me that the MNR had enough
fish within their system to quickly utilize the additional space. The old
station’s tanks were exposed outside and prone to predation from various
birds and animals.
Also within the MNR property
is a sub-station that will remain in operation and is presently being used
to raise Simcoe-strain lake trout and brown trout. This building features
a computer-controlled pneumatic fish feeder that adjusts food pellet size
and volumes as its program warrants. Future Chatsworth plans may include
installing the same type of computer-controlled feeding system in the main
building.
Another possible future project
for the site may include a walleye and whitefish culture station and perhaps
a visitor’s interpretive centre.
The funding commitment for
the new facility was announced July 12-2000 by Minister of Natural Resources
John Snobelen and Bill Murdoch, MPP for Bruce-Grey-Owen Sound.
I attended the official announcement
along with a large audience of outdoors people from local outdoor clubs.
During the 70 year life of the old facility as many as 17,000 guests a
year visited the original station.
Perhaps in future visitors,
including schoolchildren, will be once again be invited to visit the Chatsworth
Station to learn about modern fish culture.
