Water Pollution Control Guidlines that Protect Water Quality
New Homes
New home construction silt seepage phosphorus and other
chemical nutrients from lawn fertilizers are a major source of lake pollution
increasing algae and aquatic weed growth and consequently decreasing water
quality.
An MSU aquatic expert estimates that just one pound of
phosphorous could support 775 pounds of aquatic weed growth each season.
Lawn Care Guidelines to Protect Our Water Quality
- Use Non Phosphate lawn fertilizer on all lake front lawns.
- Mix code should be N-P-K of 20-0-10 or 25-0-11.
- City Law prohibits fertilizing within 25 ft of the lake water.
- Use slow release fertilizer and apply sparingly never before a rain.
- Verify that your lawn service is approved by the City of Orchard Lake Village or West Bloomfield Township and is using Non Phosphate Fertilizers.
- DoNOT ever allow fertilizer to land directly into the lake water.
- Keep fertilizer off any concrete or asphalt surfaces.
- Sweep or blow fertilizer back onto the lawn.
- Rainwater can wash these materials off the pavement and could potentially impact the water.
- A height of 3.5 inches is a general recommendation for mowing grass near the lakeshore to reduce nutrient flow into the water.
- Do NOT allow grass clippings to reach the lake water!! This is like throwing fertilizer into the lake.
- If you can t find any Zero phosphate fertilizers the following is a list of low phosphate slow release fertilizers recommended by the Dept of Environment and MI State Univ.
- Corn Gluten Meal: 9-0-0
- Ringer Lawn Restorer: 10-2-6
- Fertell Lawn Fertilizer: 9-1-4
- Pursell s Sta- Green: 31-2-4
- Vigoro Lawn Fertilizer: 31-2-4
- Check and correct septic fields for leakage into the lake.
- When using pesticides use spot treatments rather than the broadcast spreader method when possible.

Lake Care Guildlines to Protect Water Quality
- If you want to reduce the amount of lake bottom muck, there
is a product on the market named AquaClear pellets.
Bacterial action in the pellets eat away at the bottom
muck, reduce odor, and remove nitrogen sources which helps to reduce weed growth.
We used the product last season and it works. To order call 800.328.9350 - Use a rake to remove near shore seaweed rather than chemicals for seaweed eradication. Weed removal reduces next year's nutrients in the water.
- Keep your lake litter free. Remove bottles, cans, plastic, etc. from the water whenever and wherever possible.
- Be sure that silt barriers are in place around all new construction.This prevents silt seepage from introducing large amounts of nutrients into the lake during heavy rains. Call the City if you notice any silt barriers that are in disrepair.
- Be careful to minimize the amount of gas or oil that spills into the lake when refueling or during minor maintenance of your watercraft.
- Ask your dealer to use environmental friendly antifreeze when winterizing your boat engine.
- Drain the antifreeze from the engine before returning your boat to the lake each spring.
- Up to 30% of Jet Ski and two cycle engine toxic oils and gasoline fuel is dumped unburned
into the water. One gallon pollutes thousands of gallons of water.
In 7 hours a jet ski produces as many pollutants as a car driven 100,000miles.
- Suggestion: switch to a cleaner four cycle engine.
Shoreline Degradation
Shoreline landscaping destroys what Mother Nature took
hundreds of years to create.
Obviously, the natural shoreline of a lake has been stable
for hundreds of years. A combination of natural forces over the centuries of tree roots, shoreline
vegetation and aquatic plants have strengthened the shoreline to the point that
it can withstand surface water runoff, ice and wave action.
Removing the natural shoreline vegetation or changing the
slope of the bank de-stabilize the shoreline allowing surface water runoff to
erode the soil and carry water quality degrading nutrients directly into the
lake.Native shoreline vegetation
and aquatic plants are a buffer zone slowing down the run off and absorbing
the nutrients though the root systems as well as holding soil firmly in place.
The cattails, sedges, and bulrushes absorb and dissipate wave energy
preventing shoreline erosion.
This is why the city and DNR consider the shoreline
landscape within 35 ft of the water as the environmentally sensitive zone.
Obviously, each homeowner should prioritize his
landscape changes based on the overall impact on the shoreline and water
quality.Every lake front owner
should consider panting a buffer zone of native shoreline vegetation at the
water edge. City permits are
required for landscaping within 35 ft of the water.
Canadian Geese Reduction is a Factor in Water Quality
Canadian Geese are a natural part of the wild life of a lake habitat.
They are a joy to observe on our lakes and ponds. However, with no
natural predators in our immediate area, they can reproduce to the point that
they become an environmental and public nuisance. It is estimated that
one goose can produce enough feces contaminant in a season that is equivalent
to dumping a 50 lb. bag of fertilizer in the lake. Multiply the single
goose's 50 lb bag of fertilizer by 50 or more geese and the amount
of fertilizer
put in the lake in one season is more than excessive, in fact it is disastrous.
Canadian Geese droppings have also been attributed to increased bacterial counts in beach water tests.
Every home owner on the lake can attest to the excess amount of messy
droppings left by a group of geese feeding on the lawn and beach areas.
The droppings require a through clean-up or a lot of fancy footwork when
walking on the lawn.
Fortunately, each spring Mark and Gayle Hoffman with the prior approval of
the DNR, have taken up the task of reducing the Canadian Geese population on
Upper Straits Lake through an Egg Replacement or Nest Destruction
Program. Since 1998 they have collected 269 eggs.
Call or email Mark or Gayle Hoffman 248.681.1473 or mail them at:

and alert them to any spring nesting geese on your property
Annual Weed Harvesting
Weed harvesting is an important lake maintenance activity that is done every
year to remove the weeds that can clog boat propellers, restrict swimming, and
stagnate the lake water.
By removing 35 to 40 truck loads of weeds from the lake each summer, we
alleviate the immediate problem plus reduce the amount of dead weeds that sink
to the bottom of the lake each autumn.
Lowering the amount of weeds sinking to the bottom reduces the amount of
nutrient laden plant matter that could decay and become fertilizer for the
following years plant growth. Also, decaying plant material takes
large amounts of oxygen out of the water making it unlivable for most fish.
The Upper Straits Clean Lake Association prefers weed harvesting over chemical
controls using aquatic herbicides. We believe minimizing the
introduction of additional chemicals into our lake water will keep our water
as pure as possible. Additionally, aquatic herbicides kill weeds that
eventually drop to the lake bottom to become nutrients for next years growth;
thereby compounding the weed problem. Aquatic herbicides are also harmful
to young fish population.
The problem weed in Upper Straits Lake is Eurasian Water milfoil in the water and Purple Loosestrife on the shore.
The following is a means to identify the weeds in our lake:
Weed Harvesting: 2006
Each spring the Upper Straits Clean Lake Association asks for your donation to
pay for the Weed Harvesting. Watch for the request in the mail in early
spring or mark your May calendar to send in your contribution to the
City of Orchard Lake Village WQIF.
Or now you can click on the link below to open the Weed Harvesting Form.

Once the file is open you can print it directly from the page or save it your computer to print
later. Then you can mail it or print it and bring to the city offices along
with your donation.
Swans on the Lake
The Swans on Upper Straits Lake are gracefully beautiful and beneficial. One
of the most beneficial attributes of Swans is that they are weed eaters who
spend the majority of every day dipping their long necks into the water to eat a
variety of weeds from the lake. The other possible benefit is that
they are territorial and once established will chase Canadian Geese out of their
area.
During their breeding season and especially when they have a brood of young
cygnets the larger males are very protective of their families. Although
normally peaceful, there are times when they don't distinguish between Canadian
Geese and Jet Ski operators in their territory and will feign attack with a wing
flapping hissing action. It is a frightening experience for the Jet Ski
operator, however, the best defense in one of these confrontations is a loud
blast from an air horn or if none is available, a hasty retreat out of the area
is recommended.
The large flapping wing can seriously harm a Jet Ski operator. Although we
don't know of anyone on Upper Straits Lake who as ever been hurt by a swan.
My personal observation and conversation with other lake residents is that
the male swans only attack moving Jet Skis because they are closest to the size
and shape of another male swan or Canadian Geese. They have never bothered
pontoon boats, speed boats, paddle boats, or bathers whether they are children,
or adults.
Although a feigned attack by a male swan is frightening, any form of
retaliation towards these peaceful birds will not diminish their notorious
instinct to protect family and territory. So if you are on a Jet Ski, carry an
Air Horn if swans are in the area.
Swans are a protected species and hurting one with a rock or sticks is
against the law and punishable by a fine and possible incarceration.
There are three varieties of swans in North American and two of those, The
Whistling Swan and the Mute Swan, are visitors to our area. The Mute Swans live
on Upper Straits Lake. They can be identified by their orange bill with a black
knob on their forehead between their eyes. The adult Whistling Swan has a black
bill and are not seen vary often on the lake.
We have counted as many as 50 plus adult Mute Swans living on our lake. One
pair this year had seven cygnets in the spring but by the end of the summer
there were only three left.
Frogs are Sensitive to Water Pollution
Since we plan to have a Frog Race this summer for the children on the lake,
here is some interesting information about our amphibian friends and how they
can predict water quality.
Amphibians are very sensitive to pollution and habitat degradation, so
monitoring can record how habitats change for better or worse. The number of
frog and toad species found may be affected by the amount of impervious surface
in the area. Scientists have determined that water quality typically decreases
when watersheds become 15% - 20% covered by roads, parking lots and rooftops.
Data from 1998 suggests that survey blocks with zero to one species had
impervious surface coverage of about 21%.
This is one reason why there are city and township ordinances limit lot
coverage with house size and impervious surface coverage so as to insure better
water quality.
Twelve (12) species of frogs and toads likely to be found in our area:
- Wood Frog
- Spring Peeper
- Western Chorus Frog
- American Toad
- Northern Leopard Frog
- Pickerel Frog
- Cope's Gray Treefrog
- Gray Treefrog
- Green Frog
- Bullfrog Blanchard's
- Cricket Frog
- Fowler's Toad (restricted to sandy shoreline areas along Lake Erie and Lake Michigan)
