Introduction
The Kawartha Lake Stewards Association (KLSA) is a volunteer-driven, non-profit organization of cottagers, year-round residents and local business owners in the Kawartha Lakes region. The Association was initially established to provide a coordinated approach to lake water monitoring by testing for phosphorus, water clarity and E.coli bacteria during the spring, summer and fall. While the activities of the Association have expanded significantly over the years, lake water monitoring continues to be a focal point. This document provides detailed instructions for the many volunteers involved in KLSA water testing.
The document is divided into three main parts – this first section contains information applicable throughout the region and separate annexes that provide information applicable to the Eastern and Western Kawartha Lakes respectively.
Payment
Phosphorus testing and Secchi disc measurements are conducted under the auspices of and funded by the Provincial Lake Partner Program. KLSA volunteers are involved in the collection of water samples and Secchi disc measurements but there is no direct financial cost incurred by either the KLSA or those involved in this testing.
E.coli testing is coordinated by the KLSA but funded by individual lake, cottage and road associations, local organizations or interested individuals. The annual cost is $60 per site for the six tests that are conducted at each site between July and September.
Payment for E.coli test sites is due by July 1st and must be paid to the KLSA using the form below. If you are also making a donation to the KLSA, it is essential that you clearly identify the portion of your payment that is for E.coli testing, including the associated site number(s).

Phosphorus and Secchi Testing – General Guidelines
The phosphorus and Secchi testing is conducted under the auspices of the Provincial Lake Partner Program. Test kits are mailed directly to those involved in the program. Water samples and Secchi measurements are returned to the Dorset Environmental Sciences Centre by mail.
Detailed instructions for the conduct of phosphorus and Secchi testing are included with the test kits. Following are a few brief points that will assist in planning your participation:
- You should receive your testing kit by the end of April. If you have not, please contact the Lake Partner Program (lakepartner@ontario.ca, 1-800-470-8322).
- Samples for phosphorus testing are collected on or around the first of the month, May to October; 6 tests in total. The exception is May, which is better in the middle of the month when the lakes have mixed.
- The May test is important because it establishes a baseline for the year. If you cannot get out in May, please ensure you test at the beginning of June.
- Try to follow the schedule as closely as possible. If you cannot sample on the suggested date, please do so as close as possible to the suggested date; either before or after. Try not to miss a date, particularly June to September; those four measurements are critical.
- Be consistent. Take your samples and Secchi readings at the same location, at the same time of day and to the maximum extent possible in similar weather.
- Please label your sample exactly as it is in the list below. These are long established site names and it is important that they be retained to enable a year-to-year comparison. Do not change the wording as it is very confusing for the Lake Partner people who are dealing with hundreds of samples. For example, “Clear Lake: Mackenzie Bay” is good; “middle of Mackenzie Bay” causes unnecessary confusion.
- If you are collecting samples at multiple sites be very careful not to mix up the samples. Ensure that they are labeled correctly.
- You are welcome to send in your Secchi readings with each phosphorus sample rather than waiting until the end of the year when they sometimes get forgotten.
- At the end of the season, if you have leftover kits please return them with your last sample; they can be recycled and reused. As well, please return the filter and associated equipment.
- Annual data reports are available on the Lake Partner Program website in January, on the FOCA website and published in the KLSA Annual Report.
- If you are unable to do the testing next year and have been unable to find a replacement, please contact one of the KLSA coordinators.

E.coli Testing – General Guidelines
E.coli testing is coordinated by the KLSA but funded by individual lake, cottage and road associations, local organizations or interested individuals. Lake associations are encouraged to oversee the testing on their lake and endeavor to ensure a reasonable distribution of test sites by encouraging individual cottage and road associations to participate by sponsoring a site in their area.
Six E.coli water samples are collected at each site throughout the summer commencing immediately after Canada Day and concluding after Labour Day. The intent is to collect the samples after busy weekends when there has been substantial activity on the lakes. Refer to the schedule on Page 1 for sampling dates.
The annual cost for E.coli testing is $60 per site for the six tests that are conducted at each site between July and September. Payment is due by July 1st and must be paid to the KLSA using the form on Page 2 of this document.
Selection of E.coli Test Sites
E.coli test sites are selected by the organization or individual sponsoring the test. Following are some considerations when selecting E.coli test sites:
- The water should be 1 to 1 ½ metres deep (3 to 5 feet). In shallower areas there is the risk of getting sediment in the sample
- Generally, you will want to test in areas where there may be a problem such as:
- Areas of poor circulation, such as quiet bays
- Inflows from agricultural areas
- Inflows from wetlands
- Areas where waterfowl are numerous
- Marinas
- Areas where live-aboard boats dock
- Popular swimming areas (although the Public Health Unit tests most ‘public beaches’)
- Areas where you might expect change or development in the near future
- Inflows in general, as upstream conditions may change unexpectedly
- Avoid changing sites haphazardly. Data will be more valuable if sites are maintained from year to year to provide a baseline, identify long-term trends and observe the effect of weather on E.coli counts.
- Notwithstanding the previous consideration, if, after three or four years, a site proves to have extremely low counts, it may be appropriate to dedicate the resources to another site of greater concern.
- Ensure that site identifiers are used consistently from year to year. Do not reuse an old site identifier for a new site. Assign a new unique identifier to a new site.
Laboratories
The KLSA E.coli test program uses two laboratories for the analysis of E.coli water samples.
Samples collected in the Eastern Kawartha Lakes – generally the East Shore of Pigeon Lake and east – are analyzed at SGS Lakefield. Detailed instructions for those taking samples to SGS Lakefield are provided in Annex A. KLSA E.coli testing in the Eastern Kawartha Lakes is coordinated by Kathleen Mackenzie. Refer to page 1 for contact information.
Samples collected in the Western Kawartha Lakes – generally the west shore of Pigeon Lake and west – are analyzed at the Centre for Alternative Waste Water Treatment (CAWT) at Fleming College in Lindsay. Detailed instructions for those taking samples to the Centre for Alternative Waste Water Treatment are provided in Annex B. KLSA E.coli testing in the western Kawartha Lakes is coordinated by Douglas Erlandson. Refer to page 1 for contact information.
At the start of the season, volunteers can decide which laboratory they prefer to use but then must continue to use the same laboratory for the remainder of the season.
Bottles, Labels and Chain of Custody Forms.
Bottles, labels and Chain of Custody forms will be available for pick-up at the KLSA Annual Spring Meeting. Note that there are slightly different requirements depending which laboratory you are using so please ensure that you get the correct materials.
If you are unable to attend the meeting and are unable to have somebody pick up the materials for you, please contact the coordinator for your region. Refer to Page 1 for contact information.
Bottles are also available at the laboratories and can be picked up in small quantities (less than 15) when samples are delivered for analysis. If you require a large number of bottles, contact the laboratory to place an order.
E.coli Log
Volunteers conducting E.coli testing are asked to maintain an E.coli log to record weather conditions and other factors that may affect the E.coli count. A record of recent rainfall is particularly important because heavy rain tends to flush contaminants into the lakes. A blank E.coli log is enclosed. Please complete the log throughout the summer and submit it at the end of the season in accordance with the instructions on the log.
Collection of E.coli Samples
This section provides general guidance for the collection of E.coli water samples. Careful adherence to these guidelines is essential to minimize the possibility of contaminating water samples. Remember, healthy human faecal material contains about l00 million E.coli per ¼ tsp. Even when you’re clean, you’re germy. Skin or clothing can easily contaminate. Adhere to the following protocol when collecting water samples for E.coli testing.
- If you are collecting more than one sample, mark the bottle with a waterproof marker so that you can affix the correct label after the sample is collected and the outside of the bottle is dry.
- When collecting the sample, use a clean pair of nitrile/latex gloves. If gloves are not available, wash your hands with soap and water before collecting the sample. Unscrew the lid and collect the sample from a representative location. Do not place the cap where it can become contaminated. Do not let the open mouth or neck of the bottle touch any clothing, fingers or unsterile objects before or after collection of the sample. Do not breathe in the direction of the sample. Turn your head to the side while the sample is being collected.
- Using a wand or holding the bottle near the base, plunge it neck down to a depth of 15 to 30 cm (6 to 12 inches) below the surface. The water should be 1 to 1½ metres (3 to 5 feet) deep at the test site. The bottle should then be turned so the neck points slightly upwards with the mouth directed toward the current. If no current exists, push the bottle horizontally forward in a direction away from your hands. (You do not want water that has touched your hand to flow into the bottle.) Try not to let wash off the hull of your boat flow into the bottle.
- Fill the bottle about 90% full. If you overfill it, don’t pour out; ‘flip’ it out. As quickly as possible, carefully replace the cap again ensuring that you do not touch the neck of the bottle or the inside of the cap. Ensure that the cap is tight.
- Keep the samples cool; approximately 5 degrees C (38 degrees F) which is refrigerator temperature. Do not freeze. It is recommended that you have an insulated container and ice packs with you when collecting and transporting the samples. Ice packs are better than ice cubes because they do not create a pool of water (potential source of contamination) around the sample bottles.
- Enter the appropriate data on a KLSA label (sample ID, the volunteer who collected the sample, and the date and time) and affix the label to the bottle. To affix the label, you may have to dry the outside of the bottle. Do so carefully avoiding contact with the neck and cap.
- Complete the E.coli log.
- Deliver the samples to the appropriate laboratory in accordance with the detailed instructions outlined in the applicable annex.
When Will You See the Results?
E.coli test results will be emailed from the laboratories to the Eastern or Western Coordinator as applicable within two to three days of the samples being submitted for analysis. The Coordinators will distribute the results to all of the volunteers and points of contact in their region. Volunteers are encouraged to further distribute the results to their lake, cottage or road associations and interested parties. The goal is to maximize distribution of the results, create awareness of the program and develop an understanding of the potential water quality concerns.
Be sure to maintain a record of the results for your sites. Although the KLSA publishes an annual Lake Water Quality Report, keeping a record of your results is ultimately your responsibility.
What do the Results Really Mean?
Results of the E.coli testing will be presented as the total number of E.coli colony forming units per 100 milliliters (E.coli CFU per 100 mL). The following examples will assist in the interpretation of the results:
- The safe swimming level (at which public beaches are posted) is 100 E.coli CFU per 100 mL. This is related to approximately 7 incidents of waterborne disease per 1000 swimming events. If 10 children went swimming 14 times over a period of time, that would be 140 swimming events, and it would be very likely that one child would experience a waterborne disease (1 per 140 = 7 per 1000) such as gastrointestinal problems or an outer ear infection. Counts of over 100 are considered significant.
- As stated in the KLSA reports, the KLSA is of the opinion that our lakes should normally be cleaner than a public beach, and we have set the trigger for retesting at 50 E.coli CFU per 100 mL.
- How serious is a count of 10 or 25? Firstly, bacteria tend to clump, so three samples out of the same bottle might give readings of, for example 10, 25, and 6. Anything under 20 can be considered low and 5 really isn’t much different than 20. Secondly, high counts can be very temporary; they may be caused by a child or a wild animal (some children might be classified by their parents/grandparents as ‘wild animals’ but in this context we are referring to beaver, geese, etc.).
- Counts between 20 and100 that happen only occasionally are likely not of concern.
- Counts which remain over 50 for two or three weeks are unusual for our lakes and warrant further investigation in an attempt to identify the source of the E.coli.
What Do You Do if You Have a High Count?
When assessing the results of E.coli testing, it is important to note that neither the volunteer tester nor KLSA has any legal obligation to report high E.coli counts. It should also be noted that the precise locations of the test site is known only to the volunteer tester. It is up to the tester and his/her community to decide who they would like to inform regarding the high E.coli counts, and what if any remedial action they would like to take.
As a general rule, the KLSA policy is that counts over 50 E.coli CFU per 100 mL should trigger a retest. In the event of a high count, a KLSA Coordinator will contact the volunteer responsible for the site to determine if a retest is both required and feasible. If a decision is made to retest, ideally the retest should be conducted as soon as possible after the original test and should consist of three to five separate samples collected at the same site.
In the event that a retest indicates a high E.coli count, the responsible volunteer in consultation with a KLSA Coordinator will discuss possible courses of action.
Enclosed is a draft letter that can be used when addressing high counts in your area.

RE: High E.coli levels in nearby lake water
The Kawartha Lake Stewards Association (KLSA) is an organization of volunteers who monitor water quality on the Kawartha Lakes. One of the parameters we test is E.coli, a bacteria which is an indicator of faecal pollution from warm-blooded animals. Our volunteers collect water samples at over 100 sites, six times per year, on a number of the Kawartha Lakes. The samples are tested by an accredited laboratory. Results are reported to the KLSA Coordinator and to the KLSA Volunteer who submitted the sample.
Recently, the results of the KLSA testing showed high E.coli counts in your region, specifically:
| DATE | LOCATION | E.coli/100 mL |
To put the results in perspective:
- 100 E.coli per 100 mL (based on a geometric average of 5 readings) is the level at which public beaches are posted unsafe for swimming.
- KLSA believes that an E.coli level in excess of 50 E.coli per 100 mL on the Kawartha Lakes is cause for concern and warrants further investigation.
Neither the KLSA nor your local Health Unit is required to report or act on high bacterial counts in surface waters. The Health Unit does monitor bacterial levels in drinking water, and in swimming water at lifeguarded public beaches; however, bacterial levels in surface water are considered a ‘natural hazard,’ along with slippery rocks or sharp zebra mussels. We the public use our lakes at our own risk.
Results of all KLSA tests are published in our annual report (see www.klsa.wordpress.com) but sample sites are given code names so that specific locations are not identifiable.
If you are concerned about these high counts, here are some things you may want to do:
- Try to identify the source of the bacteria. It might be from waterfowl, or water flowing from an area with a high concentration of wildlife such as wetlands or a large lawn adjacent to the lake that attracts a large concentration of geese. It might be from a malfunctioning septic system. If there is evidence that the source of the bacteria is the result of a malfunctioning septic system, you should contact the local Health Unit. The KLSA would be interested in your ideas on why counts were high.
- Try to lower bacterial levels. If waterfowl (Canada geese, seagulls) seem to be the problem, there are a number of deterrents. If too much runoff seems to be the problem, perhaps local shorelines need more vegetation. If a stream from a wetland area is the source, perhaps you need to be aware of bacteria levels, and swim in an area further from the inflow. Often counts are high only after a heavy rainfall.
The KLSA, unfortunately, does not have the expertise to identify sources of bacteria, or identify methods that will be guaranteed to decrease bacterial counts. We do, however, have some information that we can provide to you if you are interested in pursuing these issues.
Bacteria levels can change quickly from hour to hour and from place to place. These results are valid only for the times and locations tested.
KLSA advises shoreline residents if five samples taken at one location and time have a geometric average of over 100 E.coli/100 mL; however, KLSA collects samples at each location a maximum of six times per summer. If you are concerned about the water quality in your area, you may want to conduct more frequent testing.
We hope you find this information useful. Please contact the KLSA Coordinator for your area if you would like to discuss the results or obtain additional information.
