Lake Life: What is a Seiche?

A seiche is a standing wave oscillating in a body of water, like the water that sloshes back and forth in a bathtub or cup of water when disturbed. They typically occur in enclosed waterbodies such as lakes, reservoirs, or even swimming pools. These waves can be surface waves or internal waves. 

What causes a seiche?
They are typically caused by strong winds and rapid changes in atmospheric pressure that push water from one end of a water body to the other. After the wind event, the water rebounds to the other side of the enclosed area and continues to oscillate back and forth for hours or even days, depending on the size of the lake. 

Seiches may be noticed under ordinary water conditions as a result of periodic changes in water level or underwater currents associated with the oscillating movement. At some locations and times, these sea-level oscillations and currents may produce hazardous or even destructive conditions. Internal waves form that can be as high as 10 to 30 meters, all unseen from the lake surface. 

Seiche waves generate currents and turbulence that rhythmically flow back and forth. These currents can cause bottom water to come to the surface, and can also mobilize lake sediments and carry them into the water.

To learn more about seiches, watch the video from Larratt Aquatic Consulting Ltd.

The Importance of Measuring Dissolved Oxygen and Temperature in Lakes

Oxygen is essential to nearly all organisms on earth including life in lakes. Given that fish breathe oxygen dissolved in water (referred to as dissolved oxygen or DO), the sport fisheries and healthy aquatic ecosystems that many of us enjoy, are absolutely dependent on water having an adequate supply of DO. Its concentration also has a great effect on the biochemical nature of a lake. Long-term changes in oxygen concentration, especially at the lake bottom, can markedly affect nutrient availability and alter the productivity of the entire lake. As such, oxygen is one of the most important resources influencing lake management and its measurement should be part of any lake sampling program. 

What is Dissolved Oxygen?
Dissolved Oxygen (DO) is the amount of oxygen (O2 ) molecules that are dissolved into the water. The amount of O2 that is dissolved in a lake depends on several factors including the mixing that occurs during the overturn of a lake, the amount of wind action a lake experiences, the temperature of the lake, the number of plants that photosynthesize in the lake, and daily fluctuation patterns. 

The transfer of oxygen from the air to the lake is facilitated by increasing the surface area exposed to the atmosphere. The surface area of a water body in contact with the atmosphere is increased by wind-driven waves and ripples, as well as by forcing water into droplets by splashing over obstacles or forcing through a fountain, for example. 

While O2 transfer to a water body is primarily through the atmosphere, photosynthesis by aquatic plants also plays a role in the amount of DO in a lake. The net effect on DO concentration is usually very small or neutral since comparable amounts of DO are consumed by these same organisms at night through respiration, when photosynthesis is not actively occurring. In addition to the respiration needs of photosynthetic organisms during darkness, oxygen within the system is also consumed through aerobic respiration by other organisms including: aquatic vertebrates and invertebrates, and bacterial and fungal communities involved in degrading dead plants and animals. 

How do DO and temperature change throughout a lake?
Oxygen concentrations and cycling are mainly dependent on the lake thermal stratification patterns which are seasonally variable. Thermal stratification is a physical response to the effect of solar heating to water’s properties of temperature and density. Generally, water density decreases as temperature increases. Warm water is less dense than cold water so it will be found towards the surface and cold water will be found near the bottom of the lake. If this held true for the winter, ice would form on the bottom of lakes. Ice, floats due to the expanded volume of water molecules when in the solid, crystal phase. Because water expands as it freezes, ice is slightly less dense and a bit lighter than water. Therefore, water is most dense at 4°C – not at 0°C when it freezes. 

During the spring and fall, lakes become completely mixed when temperatures are similar top to bottom, and wind energy overcomes the reduced temperature and density differences between surface and bottom waters. Water temperature and density are similar throughout the lake depth and a complete mixing of water, oxygen, and nutrients can occur. This is called turnover.

With the onset of summer, the lake’s vertical oxygen profile will begin to change as the lake warms and separates into layers controlled by temperature and thus water density (Figure 1). The upper layer of water will have contact with atmospheric oxygen and light allowing for diffusion of oxygen into the water and oxygen production by photosynthetic action of rooted aquatic plants and algae. This oxygen will not, however, be available to underlying waters. Waters of the lower layers in the lake have no contact with oxygen during the summer and are too dark to support most photosynthetic plants. The thermocline is found in the middle of the lake and is defined by a temperature change of at least 1°C per vertical meter and marks the transition between the top and bottom layers. This temperature/density gradient can be very sharp and can effectively prevent the mixing of the top and bottom layers. 

Figure 1. Lake stratification in the summer

The depth of the thermocline and overall lake stratification depends on factors including the local climate and the size and depth of a lake. In order to capture changes in the water column, DO and temperature should be measured every 1 meter from the surface to the lake bottom at regular intervals throughout the ice-free portion of the year.  

Why take dissolved oxygen and temperature profiles?
A profile is done by measuring DO and T at regular intervals (e.g., every meter from the lake surface to 1 m above the lake bottom). By developing an understanding of what DO and temperature look like from the surface to the bottom of the lake, more insight can be gained concerning the health of the lake. With climate warming, it is becoming increasingly important to document DO and T profiles for lakes in order to better predict locations and time periods that may experience increased or decreased DO concentrations in relation to changing temperatures. 

How to take DO and temperature profiles?
The best way to measure DO and temperature in a water column is to use an oxygen meter which measures the amount of dissolved oxygen in an aqueous solution and has a built-in thermometer so that temperature can be recorded with every DO reading. There are other methods available to measure DO such as the Winkler method, however, these methods are more cumbersome, time consuming, and more prone to user error, making it challenging to obtain an accurate profile of a lake. DO instruments can be purchased at a reasonable cost and are relatively easy to use by lake stewards, requiring  only a short training session.

Conclusion
When assessing water quality and the health of a lake, dissolved oxygen is one of the most important parameters as it is essential for the survival of aquatic organisms. When oxygen becomes too low, fish and other aquatic organisms become stressed and may die. Nutrient availability and productivity of the entire lake rely on the concentration of DO in a lake, so it is important to monitor for changes in order to implement best management practices. 

By taking profiles of a lake, it may be possible to detect changes to the depth of the thermocline, or changes in the time of lake turnover, which can have marked effects on DO and nutrient cycling. Due to the sensitivity of lakes and lake ecosystems to climate change, it is important that proactive measures be taken to better predict how lakes throughout BC will respond. The more lakes that provide temperature and DO profiles, the more data points there will be for different regions and lake characteristics so that steps can be taken to mitigate impacts or provide information in advance of an extreme shift.  

If you would like to learn more about monitoring dissolved oxygen and temperature changes in your lake, contact the BCLSS for information.

Lake Blitz Update

The Lake Blitz has been active since the May long weekend, the project kicked off with the launch of the Lake Biodiversity Photo Challenge. Since then, we have met with stewardship groups in Ontario and BC, and have developed Lake Blitz hubs with the regional BC Parks, Wildsight Revelstoke, Bay Area Restoration Council, and the BC Lake Stewardship Society. We currently have 50 active monitoring volunteers who are gathering temperature and photo data on their local lakes. The majority of the participants are from BC and Ontario, although we have lakes being monitored in Yukon, Quebec, and Nova Scotia.

The photo challenge has been a huge success with over 200 photos entered from lakes across Canada. Winners will be announced at the end of August so stay tuned!

Our social media team has been sharing details about the Secchi Dip-In event as well. Even the Friends of Kootenay Lake offered to lend Secchi discs for local stewards to take part. Although there has been no uptake for this offer, it will stand for next year's event as well.

In year 2 of the Lake Blitz, we expect to increase participation by engaging Lake Blitz Hubs earlier, before their capacity is maxed out and more can plan to integrate the Blitz into their summer monitoring programs. We are also lookin forward to developing monitoring kits specific for the Blitz and, if possible, meet the needs of BCLSS citizen science programs.

Wake Boats on Small Interior Lakes and Rivers by Jim Davies

The continuing development and popularity of wake boats has resulted in more and more of these types of watercraft impacting interior lakes and rivers. While many groups have expressed concern over the new introduction of waves big enough to free surf on, requests to Transport Canada to regulate these types of watercraft were met with little response: mainly  due to no scientific documentation to legitimize the issue. A cohesive effort is required to convince Transport Canada of the need to allow Local Authorities the ability to regulate the operation of wake boats on small interior lakes and rivers.

Wake boat manufacturers continue to develop boats that can create bigger and better shaped waves to free surf on. This is done by installing ballast tanks, trim tabs, and more powerful engines. The shoreline impacts of these waves are evident. Erosion, sediment, wildlife nesting, habitat and property damage from far larger than natural occurring waves.

Independent scientific studies were conducted by Laval University in Quebec and Larratt Consulting in Kalamalka Lake (2019) in B.C. These studies show that the required distance to dissipate wake boat  waves is 300 metres. Traditional recreational watercraft are designed to plane quickly and dissipate waves in approx. 30 metres. These studies also looked at the depth of disturbance. Wake boats create disturbance to a depth of 6 – 8 m. Aquatic plant and sediment re-suspension releases phosphorus and toxins from the lake bottom contributing to a reduction in aquatic insects and water quality. Traditional recreational boats create disturbance of 1.5 – 2 m depth. Most salmon bearing rivers are 6 m or less in depth and less than 600 m wide. The impact on fry and spawning is a concern.

There are fortunately many larger Interior lakes where wake boats can be safely and environmentally operated on. Present Transport Canada Boating Regulations would require a restriction on all types of powered watercraft in order to restrict wake boats. This blanket restriction would restrict traditional users from their recreational opportunities and affecting property values.

There is an extensive process using the Local Authorities Guide in order to apply for a Boating Restriction. Consultation with Indigenous Peoples, business, public, and property owners is required. This process insures that any lake where wake boats can be operated on without negatively impacting the environment and the safety and enjoyment of all other lake users would not be restricted. Interior lakes are the nesting sites of 1.5 million ducks and loons (Ducks Unlimited).

The Heffley Lake Community Association (HLCA) has established a point of contact with the Provincial Boating Safety Officer to receive requests for Transport Canada to change the present regulation and to permit Local Authorities to apply for a specific Ballasted Wake boat restriction, without restricting other types of powered watercraft. Contact Jim Davies (Vice-President HLCA) for further information at

Remembering David Schindler by Rick Nordin (BCLSS Vice President)

David Schindler was the most well known and respected freshwater ecologist in the world. He passed away March 4th 2021. His early career was spent doing research on eutrophication and acid rain at the Experimental Lakes Area in North-Western Ontario near where I grew up. Much of his later career was spent at the University of Alberta where he was involved with research on a number of scientific issues like the oil sands and climate change. He published many important papers but was also an environmental activist, lobbying and speaking on environmental issues. He believed that it was essential for scientists to communicate science to the public and to policy makers.
 
He had a strong British Columbia connection. In his retirement he lived at Brisco near Invermere. A very memorable remembrance for me was at a BCLSS LakeKeepers workshop organized by the Columbia Lake Stewardship Society in 2016. In a conversation with Kat Hartwig, she mentioned that David Schindler was interested in what we were doing and asked if he could attend and perhaps give a short talk on the importance of phosphorus in lake ecology. I enthusiastically said yes and he participated in the workshop and contributed information and comments from his huge base of knowledge and experience and was especially pleased to go out on the lake in the boats that had been arranged for the workshop field session and comment on the sampling we did and his observations of the lake. 
 
His wisdom, energy, and insight will be greatly missed.

Announcements and Reminders

 
Inspect aquariums to help prevent spread of invasive mussels
From the BC Ministry of Environment and Climate Change Strategy: Anyone that has a moss ball (marimo moss ball) in their aquarium is being asked to inspect it for invasive zebra mussels now that the highly invasive species has been found in a number of locations throughout the province.

Anyone who finds zebra mussels can call the Report All Poachers and Polluters hotline at 1-877-952-7277 to report their find. Moss balls can safely be deposed of by 1) placing them in a sealed plastic bag and putting them in a freezer for at least 24 hours, or 2) placing them in boiling water for at least one full minute and then let cool.

After this, place the moss ball and any of its packaging in a sealed plastic bag and dispose in the trash. Do not flush moss balls down the toilet or put them in the compost. Once the moss balls have been removed from the aquarium, do not dispose of untreated water down the drain or into any residential water system or waterway. More information on how to treat aquarium contents can be found at https://www2.gov.bc.ca/gov/content/invasive-mussels/moss-balls-disposal.

Calling all BC Lake Stewardship and Monitoring Program Volunteers
It is time to dust off your sampling equipment! The BCLSS will be contacting Level 1 (Secchi and temp) volunteers to ensure you have everything you need for this monitoring season, which runs from April to September (or later for some lakes). Remember when planning your monitoring that we require at least 12 evenly spaced readings throughout the season and that these observations should be taken between 10 am and 2 pm.

The BCLSS and the BC Ministry of Environment and Climate Change Strategy work in partnership on volunteer lake monitoring programs to ensure high quality data is collected from lakes in BC. This promotes community-based involvement and means healthier, better manage lakes in the province.


Ice On/Off Data
Ice events - the freeze and thaw dates of waterbodies - are easily recorded changes that, with the help of volunteer observers, can help us monitor the effects of climate change on our lakes. The BCLSS submits ice on and ice off data to IceWatch, part of the NatureWatch suite of national volunteer monitoring programs designed to help identify ecological changes that may be affecting our environment. Please submit the ice on and ice off dates of your lake to the BCLSS. A data form can be found here.

Habitat Conservation Trust Foundation PCAF Grants
The Public Conservation Assistance Fund provides small grants to organizations and individuals who need financial help to implement a conservation project. Approximately $150,000 is provided each year to help implement on-the-ground conservation work, with a particular focus on hands-on, community-based, and public awareness initiatives. Grants will be due in Spring 2021 - now is a good time to start thinking about projects. More information can be found on the HCTF website.
The BCLSS is available to help our members with applying for grants of all types. Please contact the office for assistance.
