A day in the life of a Watershed Monitoring Specialist

Electrofishing defined

Fish are considered to be an excellent indicator of aquatic health. An effective method of collecting fish is through a technique called electrofishing. This tool involves the use of a battery-powered backpack that puts an electrical current in the water. The current temporarily stuns the fish and allows us to net them out of the water. The fish are then taken to shore and are weighed, measured and released back into the water unharmed. Any changes in the fish community (e.g. numbers, species or weight) are invaluable in helping us guide planning and management decisions.

7.15 a.m. Arrive at the office before my summer crew arrives. There are few cars in the parking lot at this time of day, and it’s still relatively cool outside. Sign in at reception, work at my desk, check e-mails and voice messages to make sure there’s nothing urgent to deal with. In the midst of completing a few outstanding items and replying to an e-mail, I find that the crew has arrived.

8.30 a.m. Update the crew on the plan for the day. After loading the truck with our equipment from another facility down the road, they’re back at the office and then we’re off to the site we’ll be working on that day. We leave the suburban metropolis of Mississauga and are quickly surrounded by farm fields. Driving further north we reach the rolling hills and spectacular scenery of the escarpment, drive over them and continue north into Orangeville.

9.45 a.m. We’re at our site. Meet our volunteer for the day ( a Ph.d candidate from the University of Guelph ), unload the truck and set up our equipment. All of us suit up in the same pair of waders we are going to wear for the rest of the day (talk about smelly ).

10.15 a.m. I strap on the 30 lb back pack electrofisher. And we begin!!

10.45 a.m. The fish come up fast and furious but our able netters caught them all.
We finish fairly quickly, and except for getting stuck in the mud, someone’s grass allergies acting up and moving (what seemed like) miles of grass off the creek so that we could see the fish we were capturing, the site went quite smoothly. We’re all quite hot at this point, and welcomed the quiet and less strenuous activity of inventorying what we caught. We load up our truck again, and move to the next site up the road.

11.30 a.m. We’re at our second site of the day. Unload again, set up again, strap the backpack on again.

11.40 a.m. My pants are starting to stick to my legs, the mosquitos are quite hungry and we had a bunch of old cars staring at us from across the river.

12.30 p.m. In just about an hour, we’ve completed electrofishing, inventorying, and recording. I help the crew load up the truck, and then leave them to finish the next site.

12.40 p.m. It’s lunchtime, and my stomach is angry at me for the lack of food.
I make my way back to the office (about a 45 minute drive), and stop off to buy lunch.

1.30 p.m. Arrive at the office with just enough time to eat (but only have 10 minutes to do so), and I’m already late for a meeting. At the meeting, Communications pesters me for my submissions for the newsletter.

2.00 p.m. Whew! this meeting is over, and I can go back to my desk, work on a couple of things (including this article!),

2.30 p.m. Pulled into another quick meeting.

3.00 p.m. Finished replying to all the requests for information, prepared some reports, followed up with some landowners.

4.00 p.m. The crew is back in the office (hot, smelly, tired but still smiling), and we have a quick chat about the next day’s schedule. I’m back to my voice mails and e-mails, and don’t look at the clock again until it’s….

4:45pm. I’m ready to go home! I hope dinners on the table!

  Special Permit for rainbow trout in Belfountain

In response to an illegal/accidental release of rainbow trout to the West Credit River, MNR has issued a special permit to CVC for anglers at Belfountain Conservation Area. The source of the fish and the means of their release into the river are under investigation by MNR.

Rainbow Trout

Rainbow trout are not native to the West Credit and this illegal/accidental release is not in compliance with the Credit River Fisheries Management Plan (CRFMP). This species may compete with native fish species. Existing regulations for the Credit River and its tributaries in the Town of Caledon upstream of Old Base Line state a possession limit of zero (0) for all species of trout. In an effort to control/remove the rainbow trout from the West Credit, MNR is temporarily allowing these fish to be harvested within the Conservation Area.

Members of the public may register with their Outdoors Card at the Belfountain Conservation Area gatehouse for a copy of this special licence that permits the possession limit of 5 rainbow trout for Sport Fishing Licence holders and 2 rainbow trout for Conservation Fishing Licence holders. The licence covers the West Credit River from Belfountain Conservation Area downstream to Forks of the Credit Road. Other special regulations for this water still apply i.e. artificial lures with a single-pointed barbless hook must be used. No live organic bait allowed.

Under the naturalists’ eye – the truth about turkey vultures (Cathartes aura)

Many people have noticed that rising temperatures have been accompanied by the return of a black bird with a wing-span of almost 6 feet (1.8 metres) that circles fields, forests and roadsides. Unfortunately, many people do not know what this bird is, and those that do, often misunderstand its habits.

The common name of “turkey vulture” only serves to confuse the identification or understanding of this bird. ‘Turkey’ refers to an entirely different species of bird, while ‘vulture’ tends to mean aggressive, greedy, living on live prey, which for the turkey vulture, is not the case. On the other hand, their Latin name, Cathartes aura, means “purifier”, which is a far more accurate description of this species’ role in the environment. What follows are some common misconceptions about turkey vultures, as well as the truth behind the myth.

Myth: Circling vultures indicate that a dead body is nearby.

Fact: Circling vultures do not indicate the presence of a carcass. Rather, circling vultures are either gaining altitude for long flights, or are actively searching for food. The turkey vulture is one of the only birds that fly with their wings in a dihedral (V-shape). They are the most graceful in flight, and can soar for hours at high altitudes without flapping their wings. Turkey vultures will descend (at speeds approaching 100 km per hour) if there is food present. Their occasional necessary flaps and takeoffs are quite laborious, and the birds often fall victim to predators and cars as a result.

Myth: Turkey vultures have poor eyesight.
Myth: Birds (including turkey vultures) can’t smell.

Fact: Turkey vultures have excellent eyesight, but, like many other birds, have poor night vision. Turkey vultures are also one of the only birds in North America with a sense of smell. This heightened sense allows them to pick up the “scent” of mercaptan, a gas that is produced at the beginning of the decay process.

Myth: Turkey vultures will carry away your pets.
Myth: The presence of turkey vultures means that something is dying in the vicinity.

Fact: Turkey vultures DO NOT eat live animals (or children for that matter). In fact, turkey vultures are known to prefer the meat of recently killed herbivorous animals (e.g. rabbits and squirrels) and will tend to avoid carnivores (e.g. cats, dogs and coyotes).

Myth: Turkey vultures are buzzards.

Fact: Buzzard is the correct term for a family of hawks. For example, the European buzzard, Buteo buteo, is closely related to the North American red-tailed hawk. In North America, the term is often employed incorrectly to describe vultures. This probably dates back to the arrival of the first English colonists. There are no vultures in England, so these pioneers probably gave the common term "buzzard" to all the soaring figures above the New World.

Some other turkey vulture facts:

• For years, the turkey vulture was thought to be a species of raptor, which was closely related to falcons. In fact, North American vultures are more closely related to storks and ibises.

• The turkey vulture’s high resistance to bacteria and disease allows them to consume rotting flesh that could otherwise contaminate the surrounding environment, thus serving as nature’s roadkill and carcass collectors. Like the Latin name suggests, they are indeed one of nature’s purifiers.

• Their heads and necks are featherless for the sake of cleanliness when feeding. The red colour helps the bird to “bake” leftovers off of the body following its meal.

• Because of the nature of their diet, the turkey vulture’s urine is acidic enough to kill any germs on their legs. Turkey vultures will therefore urinate on their legs to kill bacteria, and since they do not perspire, it helps to cool their legs off too.

• Turkey vultures can glide for six hours straight without flapping a wing.

• A group of vultures is called a "Venue", while vultures circling in the air are a "Kettle".

• The oldest known turkey vulture, Tolouse, is 33 years old, and lives at the San Francisco Zoo.

If you’d like more information on turkey vultures, please see The Turkey Vulture Society’s website at: http://vulturesociety.homestead.com/. Although the society is based out of Missouri, its website is full of information that is relevant to Ontario residents.

Posters on Impact of Activities on Water Quality

In the spring of 2005, staff from Conservation Halton, the City of Mississauga, the Town of Oakville and Credit Valley Conservation got together to produce educational materials aimed at protecting storm water from non-point source pollution.

With the support of 15 other community partners, a series of posters depicting common human activities and the impacts of those activities on water quality was printed for distribution to caring communities along the shorelines of Lake Ontario, Lake Erie and Lake Simcoe. A web site supports the posters and provides additional information regarding water quality.

The Working Group members who originated this effort provided complementary copies of the Storm Water poster series to their respective communities to assist in their efforts to promote sustainable water use.

We all share a common purpose; clean water to make all our lakes “Great Lakes”. Copies of the posters can be obtained at our administration office. For further information about protecting storm water quality, visit www.cleanlakes.ca.

Water Conservation 2005

With the arrival of summer, we look forward to warm weather and being outdoors. In addition to all the fun summer brings, it is important that we remember to protect our environment by wisely using the resources that are available to us. One way that we can do this is by conserving water. Careful use of water saves us money, ensures that water is available in the future, and limits discharges to our waterways.

Credit Valley Conservation would like to take this opportunity to remind its citizens of the importance of conserving water particularly during the hot, dry summer months. The following passages provide tips on how you can help save water when water demands are typically higher than normal.

To Help Save Water Outside:

To help conserve water outdoors use water wise gardening practices, principles and techniques. These will save you both time and money when it comes to developing your gardens. By following the tips below, you will spend less time weeding, fertilizing, pruning and pumping water into your gardens, and you will also save money because you will be using less water. Here are some tips that you can use to help make your yard the blue ribbon, low maintenance, environmentally friendly envy of your block.

• Improve your soil – Heavy clay soils drain too slowly. Sandy or stony soils drain too quickly. Improve the absorption and water-holding capacity or drainage ability of your soil by adding compost or other organic material.

• Reduce your lawn – Where it makes sense, replace your lawn with tiered gardens, rock gardens, low water use shrubs or flowering trees and groundcover. Less lawn means less watering and more room for a variety of natural beauty.

• Use a cistern to collect rainwater - 1,000 square feet of roof or pavement can collect 420 gallons of water from 1 inch of rain. Rooftops or any sloping surface such as a driveway are prime "catchment" areas for rainwater. Store the collected water in a cistern, and siphon it off to water your garden or wash your car.

• Spot Water - Drier areas require more water than areas where water settles. If necessary, water dry areas by hand.

• Water the lawn only when needed - Step on the grass; if it springs back up when you move your foot, it does not need water.

• Don't water the pavement - Position sprinklers so that water lands on the lawn or garden, not in areas where it is not needed. Also avoid watering when it is windy. Wind causes water to evaporate quickly and blows water onto areas where it is not needed.

• Plant drought resistant trees and plants - Landscape with plants that require less water. These plants can be very attractive and can survive drought better than turf. Rocks, gravel, and deck areas can all be used to creatively decorate the yard.

• Consider drip irrigation systems around trees and shrubs - Drip systems permit water to flow slowly to roots, encouraging strong root systems.

• Keep lawn free of weeds - Weeds are water thieves and will rob your plants of water and nutrients. Spot spray or remove weeds as they appear.

• Accept a less than lush lawn - Grass will naturally go dormant during periods of drought, but will readily regenerate when water becomes available. Reduce traffic on stressed turf areas if possible.

• Mow as infrequently as possible - Mowing puts the grass under additional stress that requires more water.

To Help Save Water Inside:

To help save water inside the home always remember too:

• Use full loads for laundry – 0.18 m3 of water are consumed by an average load of laundry.

• Turn off the water after you wet your toothbrush - up to 0.018 m3 of water are used to brush your teeth.

• Take a shorter shower - An average shower consumes 0.45 m3 of water.

• And While You're On Vacation – Be sure to turn off the indoor control valve for all outdoor faucets, check all faucets and toilets for leaks prior to leaving and ensure that sprinkler system(s) if any, are turned off. Notify the Water Department of extended vacations so that water bills can be forwarded or payment arrangements can be made to prevent penalties.

Remember “water is life”, by conserving water we are essentially preserving our livelihood for the future. Have an enjoyable summer this year and stay safe.
