Extreme Water Levels: Impacts and Strategies Webinar Series

Water Levsl Series

Last fall our experts gave you the facts about water levels on the Great Lakes and in Georgian Bay. We answered 259 questions posed by 400 concerned citizens with experts reviewing our responses to ensure that everyone has the fact-based understanding of the issues and the limits under the existing water management systems in place. We brought this information to Municipal Councils around the Bay and after more than a year of combined effort with Georgian Bay Forever (GBF) Municipal Councils now have a solid fact-based understanding of what the issues are.

But there were even more questions asked around what actions could be taken to protect properties and shorelines around the Bay during high and low water extremes.

The Georgian Bay Association (GBA) and Georgian Bay Forever’s Extreme Water Levels: Impacts and Strategies Webinar Series is a collection of webinars aimed at answering those questions, providing strategies to adapt your property and your budget, and raising awareness about the extremes and variabilities that will impact the ecosystem and your family’s enjoyment of your favourite place on the Bay.

Each webinar focuses on different topics, and we invite you to register for all three.

Don’t Miss the Final Webinar in the Series!

Saturday December 4, from 10 am to 12 pm

Webinar 3: Septics – Insurance – Businesses

will focus on: Septics and Water Levels

  1. Septic systems. How vulnerable is your septic system? What are the options to resolve septic issues?
  2. What are the potential future impacts on potable water in high or low water events?
  3. Insurance and Planning. What are the potential impacts on property insurance? What are the benefits of long-term planning versus executing short term solutions?
  4. Coastal Infrastructure. What are the impacts on municipal infrastructure, shoreline businesses (including marinas), contractors, and other services of extreme high and low water levels? How can those impacted adapt?

Featured Expert Speakers:

  • Dr. Neil Hutchinson – Founder and Senior Scientist, Hutchinson Environmental Sciences Ltd.
  • Cheryl Evans – Director, Flood and Wildfire Resilience at Intact Centre on Climate Adaptation

Did you miss Webinar 1: What’s Happening? What’s New?

Our first in the series of three Extreme Water Levels: Impacts and Strategies webinars went swimmingly! Great speakers – strong participation – many great questions. Take a look below at key takeaways we’ve assembled from the expert presentations during the first Webinar on the pressing issues surrounding changing climate related extreme weather and water level fluctuations in the Great Lakes.

In our Saturday, October 23 webinar, our accomplished speakers walked us through what’s happening and what’s new with water levels. Here are the top takeaways:

  1. Both precipitation and evaporation are projected to increase under various climate-change scenarios, with future lake levels depending on the balance between the rates of increases. The highs are likely to be higher and the lows lower as we move into an increasingly uncertain future.
  2. The Council of the Great Lakes Region (CGLR) released Action Plan 2030 in June 2019. The Action Plan addresses four major challenges facing the Great Lakes region: climate change, beaches and bacteriological contamination, nutrients and algal blooms, and toxics and harmful pollutants.
  3. The CGLR is seeking to leverage federal commitments regarding a strengthened Freshwater Action Plan and the creation of a Canada Water Agency to advance the priorities laid out in their Action Plan 2030, including recommendations made to address the aforementioned four major challenges.
  4. Changes to Climate drivers – including temperature (air and water), wind speed, and precipitation – operate at different scales, both basin-wide and local. Future projections predict ‘warmer, wetter, wilder’ conditions. Lake impacts include ice (cover and phenology) and algae growth. Bluegreen algae blooms like it hot, so extreme weather events favour blooms.
  5. Additional lake impacts can be seen in wetlands, flora and fauna. While wetlands in Georgian Bay evolved within the long-term water level regime of 6.33 feet of water level fluctuations, more sewage discharges (among other factors) will increasingly tax the ability of our coastal wetlands to keep our water clean. Many plant and animal species will be unable to adapt to the effects of even an intermediate impact scenario for the future climate. Taxonomic groups depending most on water (e.g., molluscs, fishes, amphibians and lichens) will be the most vulnerable. Additional impacts can be seen in fish (e.g., less ice cover meaning lower viability) and birds (e.g., botulism bacteria being passed through the food chain from algae to invasive mussels to round goby to birds).

We learned that while there is hope, we can not afford to be complacent. We are IN a climate crisis. Greenhouse gas emissions have changed the chemistry of the atmosphere and have already contributed to changes to Georgian Bay that can’t be reversed. We must not only take individual action, but also urgently support pulling together across all levels of society and government to work simultaneously to dramatically truncate greenhouse gas emissions. This will work to deliver some future stability in the environment. At the same time, we must also work on individual adaption actions and policies for the current changing conditions. Accordingly, the next two Webinars in the GBF/GBA series will focus on what you can do to adapt to extremes in weather and water levels.

Did You Miss Webinar 2: Shorelines & Shoreline Structures

Stuctural damage water levelsOur second in the series of three Extreme Water Levels: Impacts and Strategies webinars was very informative. Our expert speakers walked us through the impacts we can expect from more intense storms and waves action and some adaptation strategies for shoreline structures.

Here are the top takeaways:
  1. Waves typically originate from wind or disturbances such as boats. Fetch, depth and wind speed/duration are key factors in wave height. Bigger storms + deeper water = bigger waves closer to the shoreline. Gentler shoreline slopes and vegetation will dampen/dissipate wave energy and can be used as the basis for creating soft but stable shorelines
  2. Wake boats should be operated in sufficiently deep water to protect bottom sediments and near shore vegetation. ‘Living shorelines’ absorb energy through the use of softer materials and live vegetation, and help buffer wave energy before it reaches shore.
  3. There is a case to be made for approaching natural assets collectively, including that they can benefit from the delivery of core services, they can be managed (which is the focus of local government natural-asset management), and they are often over-used and under-recognized.
  4. There are significant differences in the approach to the high-water mark across Georgian Bay’s coastal municipalities. Those marks that have been set are at a lower level than the 2019/20 water level, and these may need to be re-considered given higher water levels are expected in the future.
  5. Water-level changes affect the many businesses that are part of our coastal infrastructure, including by increasing their capital and operating costs related to dock systems, shore-wall systems, and shoreline properties.
  6. There are planning permission requirements for installing new/replacement docks and for relocating shoreline structures, as well as setback requirements, and some of these vary by municipality. Those involved in new construction or relocations should consider placing structures above the minimum setback from the high water mark required by the municipality to be prepared for higher water levels.
