[Img-i-arrow-green.gif]  Maynard Lake was used as a drinking water supply long ago; Thank you Mr. Kenneth Manuel.

But in the case of Maynard Lake, there is good news as follows:-

Img- animated smiley2.gif
Through the combined efforts spearheaded by ourselves with strong public support and with several Government agencies partnering with us, we herewith announce significant improvement in several indicators inclusive of the summer-2004 E.coli counts, sublittoral zoobenthos, lake phycology, and other parameters.

In addition, an experimental project carried out several years ago by the DFO at Bell and Maynard Lakes concluded that the control brook trout fingerlings survived well in Maynard Lake while the survival rate was poor at Bell Lake.

 It is cautioned though that the low E.coli counts may not be sustainable unless citizens do their part in not feeding ducks.

The original history from early-to-mid-1900s when Maynard Lake was used as a drinking water supply. Thank you Mr. Kenneth Manuel for the info:-

click for Bacterial Source Tracking (BST)- A Review
Bacterial Source Tracking (BST) of the lead indicators, Bacteroides Prevotella species, the first ever BST carried out in all of the Province:

World class Bacterial Source Tracking (BST) of the lead indicators, Bacteroides Prevotella species

BST results:

Sampling stations at the beach.

[Img-World-class expert, Prof. Kate Field PhD]
Essentially, the following report from the "The" world-class expert, Prof. Kate Field PhD of the Oregon State University on the BST based on the common anaerobic Bacteroides Prevotella species concludes that 50% of the filters were positive for one or both human markers; none of the filters were positive for the dog marker; and that all the 17 filters were positive for the non-specific fecal marker. It further states that in the obvious absence of farm animal impact, the most likely source is waterfowl since the non-specific fecal marker readily detects waterfowl fecal contamination.

For a background literature and associated synopsis on BST, see the report prepared by Applied Limnologist, Shalom M. Mandaville.

Maynard Lake Subcommittee for an experimental project- this committee has now disbanded due to total lack of cooperation from the Community Grants Program although it was Renee Roberge PEng of the EMS Department who asked us to utilize scallop shells, alas!

On Saturday April 26, 2003, a subcomittee was set up to carry out possible restoration so that the beach could once again be used intensively as in the bygone years.

One of the technologies applied, notwithstanding the varying E.coli sources, was the experimental methodology implemented in a class project elsewhere in year 2002 by Trottier, Beaton-Johnson, and Fares which has received acclaim from Director General, George Iwama PhD (pers. comm. April 17, 2003), and from Laura Brown PhD (pers. comm. May 09, 2003) of The National Research Council of Canada (NRCC), Halifax.

In addition, we have also been carrying out several educational programs for public stewardship.
