Individual & Collaborative Endeavours

We Are Proud of Our Programs and Partnerships

Working with local community organizations, residents, and other non-profit societies, the BCLSS has implemented a variety of programs to provide education and training to expand lake stewardship throughout British Columbia. Through our unique programs, including the BC Lake Stewardship and Monitoring Program, LakeKeepers, and the BC Lake Stewardship Engagement Initiative, we are proud to be empowering stewards to ensure our provincial lakes are clean and healthy.

BC Lake Stewardship and Monitoring Program

The BCLSS developed the BC Lake Stewardship and Monitoring Program in partnership with the BC Ministry of Environment to allow for greater collaboration with lake stewards.

BC Lake Stewardship Engagement Initiative

Through the BC Lake Stewardship Engagement Initiative, the BCLSS will enhance and strengthen the provincial lake stewardship sector.


The BCLSS LakeKeepers training course and manual provide an in-depth understanding of lake ecology and management.

Partnerships and Collaborations

The BCLSS partners with other organizations that share our vision of clean, healthy lakes. Collaboration leads to a larger impact, further strengthening watershed stewardship throughout the province.

LakeKeepers Workshops

Since 2009, the BCLSS has offered LakeKeepers workshops to provide training and support for lake stewardship with an emphasis on lake water quality monitoring and aquatic plant surveying.  Twenty-seven workshops have been offered since the program’s inception thanks to our generous funders.

The BCLSS LakeKeepers training courses are offered throughout the province and participants will gain a greater understanding of lake ecology and management. This knowledge leads to an increased ability to take care of their lakes through better understanding of watershed and land-use impacts. Regionally based LakeKeepers courses will also create peer-to-peer learning opportunities through networking and will address specific issues and concerns from each local area by offering optional modules for selection by course participants. 

Through LakeKeepers, the BCLSS will continue to facilitate information sharing throughout the BC water community by encouraging collaboration and connections of our member groups, partner organizations, and other interested parties wherever possible, and by sharing details of current and future projects, and past successes of our member groups through our website, social media, quarterly newsletters and e-newsletters.

LakeKeepers Manual (currently under revision)

The LakeKeepers manual is a lakeshore resident’s guide to the stewardship and monitoring of lakes. Anyone concerned or even curious about lakes in BC will find this manual useful and informative. The manual provides insight to the fascinating nature of lakes and helps readers understand basic lake function. This is especially important for individuals who wish to play an active role in managing the health of those lakes in which they are interested.

The manual is currently being revised and we appreciate your patience while it undergoes extensive technical review.

There is an increasing need for individuals and groups throughout the province to take on a greater role in stewardship activities, environmental monitoring, and water quality management. Collection of lake data by volunteers is extremely important for the protection of lake water quality as it helps establish a strong baseline of data that allows for lake health to be determined, monitored, and managed over time. Good water quality is important for aquatic life and wildlife that rely on lakes for food and habitat, and to people, who use lakes for drinking water, fishing, boating, swimming, other recreational uses, and aesthetic purposes.

The BCLSS recognizes the importance of citizen science and assists individuals and local groups with taking on a greater role in lake stewardship activities throughout BC.

In the spring of 2003, the BCLSS launched a province-wide program in partnership with the Ministry of Environment and Climate Change Strategy (ENV): The BC Lake Stewardship and Monitoring Program (BCLSMP)

Under the BCLSMP, volunteers are provided with training, equipment, and support to facilitate the collection of water quality data and observations from lakes in BC. This program strengthens the volunteer stewardship sector in British Columbia by increasing awareness of the importance and value of volunteer lake monitoring and environmental stewardship.

This program is unique in that it gives dedicated volunteers the knowledge and tools to become stewards of their favourite lake, which, in turn, means healthier, better-managed lakes in British Columbia. It also promotes community-based involvement and extensive collaboration efforts.


This program includes five different levels of monitoring. Factors affecting water quality and the resources available to each region determine the level of monitoring for a particular lake. The BCLSS currently manages all provincial Level 1 programs while ENV manages all Level 2 & 3 programs.


Weekly Summer Clarity (Secchi) and Surface Water Temperature Readings
  • A minimum of 12 readings taken, spread evenly throughout the summer
  • Provides a minimum level of baseline information about a lake
  • Valuable to obtain this level of data for a large number of lakes from different biogeoclimatic zones for climate and eutrophication research
  • Coordinated by the BCLSS 
  • MoE involvement not required


Spring Overturn Plus Late Summer Water Chemistry and Dissolved Oxygen (DO)/Temperature (T) Profile Complimented by Weekly Summer Clarity (Secchi) and Surface Water Temperature Readings
  • Provides a second level of baseline information about a lake
  • DO/T profile required can be done by BCLSS staff and volunteers
  • MoE staff could do water chemistry sampling with the assistance of the BCLSS and volunteers 
  • Sampling at multiple depths may be required if DO/T profile shows the lake is not homogeneous


Same as Level 2, Adding Multiple Depth Water Chemistry and Biological Sampling Biweekly Throughout the Summer
  • Provides more detailed information on the lake such as possible summer oxygen depletion, internal nutrient loading and plankton species present
  • Results in a more comprehensive baseline data
  • A sediment core can be taken for insight into historic water quality to assess whether the lake has changed over time
  • Can be coordinated by BCLSS staff and carried out by volunteers
  • MoE staff involvement required
  • Significantly higher cost and effort required over 1 and 2


A Level 1, 2 or 3 Combined with a Watershed Study (see Hart and Associates on the Chinney – Felker Watershed)
  • Provides relative magnitudes of potential affects of different land uses
  • Can answer questions such as: how much of an effect are septic systems having?
  • Is of great value in prioritizing management efforts i.e. put the greatest effort where there is the best potential benefit
  • Considerably more expensive than 1, 2, or 3
  • Requires the services of a consultant but can be assisted greatly by local stewardship groups and agencies
  • MoE staff involvement required


Full Watershed Assessment that includes 1, 2, 3 and 4 as well as Stream Monitoring for Water Chemistry and Assessment of Riparian Areas
  • the ultimate study, but is very expensive and time consuming
  • not practical or necessary for every watershed
  • large amount of MoE staff involvement necessary

After three years of monitoring, the data collected by volunteers from each lake will be summarized into a lake-specific report by the BCLSS. It is important to note, however, that a minimum of 12 equally spaced samples taken throughout the spring/summer seasons are required in order to collect meaningful data. The lake reports are reader-friendly and will describe the trends in the lake parameters that were monitored. The report will also provide the residents and seasonal users of the lakes with an idea of potential changes in water quality and will identify any problems associated with these changes. Where possible, the reports will make recommendations for further lake monitoring and assessment. Please refer to our library page to view lake reports already completed.

Secchi Dip-In

The Secchi Dip-In takes place during Lakes Appreciation Month, July 1st to 31st. This is an international effort of the North American Lake Management Society during which volunteers collect a snapshot of the water quality in their local lake. Volunteers from across North America have participated in this event for over twenty-five years, gathering important environmental information about their lakes. The BCLSS has been a collaborator of this event in BC since 2002!

The Secchi disk is one of the most basic tools for evaluating water quality of lakes. It measures water transparency (clarity) which is a good indicator of the impacts from human activity on the land surrounding a water body. If transparency is measured through the season and from year to year, trends in transparency can be observed. It can serve as an early warning that activities on the land are affecting water quality. 

Father Pietro Angelo Secchi, scientific advisor to the Pope, was asked by Commander Cialdi, head of the Papal Navy, to develop and test a new water transparency instrument in the Mediterranean Sea.  This instrument, now named the Secchi disk, was first lowered from the papal steam yacht l’Immacolata Concezione (The Immaculate Concenption) in the Mediterranean Sea on April 20, 1865.

The typical Secchi disk used in lakes is an 8-inch disk with alternating black and white quadrants. It is lowered into the water until the observer can no longer see it. The depth of disappearance, called the Secchi depth, is a measure of the transparency of the water. 

Transparency decreases as the amount of particulate materials – such as algae and suspended sediment –  increases. In other words, the water becomes less clear when there is more algae or sediment suspended in the water. The amount of algae that grows in a lake is affected by the amount of nutrients coming from sewage treatment plants, septic tanks, and lawn and agricultural fertilizer, as well as suspended sediments washed from construction sites, agricultural fields, urban storm runoff, or  churned upward from bottom deposits. Determining water clarity is the first step in assessing the health of a lake. 

The BC Lake Stewardship Society organizes the provincial Dip-In and submits the data to the North American Lake Management Society (NALMS). You can explore historical Dip-In data on the Water Quality Portal.

BC Lake Stewardship Engagement Initiative

The BC Lake Stewardship Society recognizes the increased need to focus on education and communication to advance stewardship throughout the province. The BC Lake Stewardship Engagement Initiative (BCLSEI) is an educational program developed in 2019 to improve the capacity of lake stewards and to complement our other well-established programs and services.

In 2018, the BCLSS led the development of the Integrated Lake Monitoring Framework (ILMF), in partnership with Living Lakes Canada, for the BC Ministry of Environment and Climate Change Strategy. This framework outlined the need to expand and enhance the volunteer lake stewardship sector and also verified that the volunteer lake stewardship sector required more training and diverse support. These needs can be addressed by increasing awareness and offering education and training opportunities. The needs identified in the report included:

  • personal contact for training and other aspects of lake management,
  • information on lake ecology,
  • support with forming a stewardship group,
  • connections with other groups who may have experience with similar lake management issues,
  • assistance with identifying funding sources for projects and equipment,
  • providing equipment,
  • regular communication,
  • assistance with defining objectives for monitoring,
  • designing an appropriate monitoring program,
  • training on correct monitoring procedures,
  • audits to correct data collection problems and maintain quality assurance of data,
  • assistance with resolution of lake management issues,
  • communication and connection with specific government agencies or representatives involved in managing certain aspects of lakes.

The BCLSS aims to fulfill these needs of the volunteer lake stewardship sector through the BC Lake Stewardship Engagement Initiative (BCLSEI), an educational program offered through meetings, presentations, and workshops. The diverse curriculum of this program is based on the needs and requests of communities being visited and can include general lake science, information on lake stewardship and citizen science, general support and advice for lake stewards, increasing awareness on lake related issues such as aquatic plants and invasive mussels, and assistance with operating a stewardship group, including information on fundraising. The BCLSEI can be adapted to incorporate more technical components such as procedural and safety training for lake monitoring and auditing of monitoring to ensure high quality data is being collected.

Virtual meetings are an integral component of the BC Lake Stewardship Engagement Initiative in response to the COVID pandemic. Virtual meeting educational topics range from general lake science (including lake-specific science), how to purchase and use a dissolved oxygen meter, and how to take Secchi and temperature readings.

Meeting with provincial lake stewards under the BCLSEI has reinforced the importance of  personalized assistance. Face to face meetings are complemented by ongoing support and outreach offered by the BCLSS through follow up emails, phone calls, and virtual meetings. Additional support is provided through educational resources, informational monthly newsletters, and sharing of any other relevant contacts or resources. This ongoing support is critical as it continues to motivate lake stewards and citizen scientists, which, in turn, ensures that lakes receive the care they need to remain healthy. Feedback from program participants has reinforced the value of this support.

The initial success of this program demonstrates that personalized contact with those that have concern for and care about our local lakes is invaluable. We aim to continue to empower individuals and groups through this program, so that they can take on a greater role in lake stewardship. 

If you are interested in having the BCLSS provide a personalized presentation, please contact us.

Water Rangers

BCLSS is a Water Rangers Ambassador!

Water Rangers has carefully designed, educational water test kits that anyone can use. They are an excellent way for community groups and schools to collect and share water quality data from lakes and streams.

The BCLSS has been using these kits with a number of school groups as well as for monitoring Como Lake in Coquitlam with the Burke Mountain Naturalists. They are very well put together, easy to use, and fun! Water data can be entered right into the Water Rangers app and are graphed immediately in the dashboard so that you can see the results over time.
