Water Quality

Perhaps nothing is more vital to the environmental and economic health of the Canada Lakes and its community than water quality.  The organization remains vigilant about threats such as acid rain, bacteria from septic pollution, and road salt run-off.  To monitor water quality the CLCA sponsors regular testing of bacteria levels and participates in two regional water testing programs: Citizens Statewide Lake Assessment Program (CSLAP) and the Adirondack Lake Assessment Program (ALAP).

CSLAP:

The Citizens Statewide Lake Assessment Program is a volunteer lake monitoring and education program that is managed by DEC and New York State Federation of Lake Associations (NYSFOLA).  Canada Lake has been participating in CSLAP since 2001.

ALAP:

Adirondack Lake Assessment Program (ALAP) is a partnership between Protect the Adirondacks! and Paul Smith’s College Adirondack Watershed Institute. Canada Lake has participated since 2003. Pine Lake has participated since 2001. East Caroga Lake and West Caroga Lake started participating in 2016. This is a high quality longitudinal scientific study with more than 75 Adirondack lakes participating in 2016. All lakes are sampled by volunteers at the same time, usually three times during the summer season.

James Long has written the following summary of the recent ALAP tests:

“Canada Lake is fairly clear. It has a moderate level of
nutrients and submerged weed beds. As such, Canada Lake is
best classified as a “mesotrophic lake” on the trophic
scale. That places it between lakes that are very clear and
have low nutrient levels (“oligotrophic lakes”) and lakes
that have high nutrient levels and large amounts of rooted
aquatic plants or algae (“eutrophic lakes”). The trophic
state of Canada Lake has been variable, but typically
fluctuates around the oligotrophic – mesotrophic boundary.
There was no significant trend in any of the trophic
indicators over the last seventeen years. A significant
source of nutrients is the large number of septic systems
around the lake. Most of the phosphorus and nitrogen from
those septic systems eventually reaches the lake.
“Water samples from 2017 were found to be circumneutral in
terms of their acidity, with an average pH of 6.6 (pH is a
scale in which a pH of 7.0 is neutral and lower numbers mean
greater acidity). We observed the alkalinity in August 2017
to be 6.0 mg/l, indicating that the lake has moderate
sensitivity to acid deposition. (The acid deposition mostly
comes from coal-fired power plants in states to the west of
New York.)
“Sodium and chloride concentrations in 2017 were 3.8 mg/l and
7.6 mg/l respectively, suggesting that the chemistry of the
lake is influenced by the 35.2 km of roads in the watershed
where road salt is applied during the winter. Chloride
concentration of Canada Lake is exhibiting a significant
increase and is currently greater than 67% of lakes
participating in ALAP. The largest source of road salt,
Park-wide, is NYSDOT application on state highways.”

Bacteria Monitoring Program:

Ongoing concerns about elevated bacteria levels lead the organization in 2007 to adopt a Bacteria Monitoring Protocol.  Since then the monitoring has not shown any locations with repeated elevated total coliform levels that would warrant further laboratory tests to further indicate possible septic pollution. This does not mean that septic problems do not exist on properties on Canada Lake. Keep in mind that the time of sampling, recent rain events and the specific spot along shore where the actual sample was collected are all factors that could alter results for a given area.

As a lakeshore homeowner, YOU have a special responsibility to ensure that your septic systems are not polluting the lake:

DO

  • Limit the water entering your tank. Use water saving fixtures. Fix toilet float valves, leaks, and dripping faucets. Spread clothes washing over the entire week.
  • Pump the tank when necessary. This means every two to three years, or as indicated by your annual inspection.
  • Divert surface water drainage away from the absorption field.  If you do not know the condition of your septic system, have the system inspected.

DON’T

  • Do not connect the basement sump pump or other “clean water” discharges to the septic tank.
  • Do not put materials down drains that will clog the septic tank (fats, grease, coffee grounds, paper towels, sanitary napkins, disposable diapers, etc.).
  • Do not put toxic substances in drains that might end up in the groundwater (cleaning fluids, oils, paints, disinfectants, pesticides, etc.).
  • Do not use chemicals to clean your system. They may interfere with the biological action in the tank, clog the drain field by flushing sludge and scum into the field, or add toxic chemicals to groundwater.  Starters are not necessary for new tanks or after pumping existing tanks.
