Water Challenges

as a result of enhanced erosion of the shorelines and water systems due to climate change is lowering water quality in the bay. The higher presence of suspended particulates lessens light penetration and can suffocate spawning grounds of waterborne life.

Higher temperatures from climate changeHigher temperatures from climate change
combined with agricultural and septic runoff are a recipe for cyanobacterial blooms, which are toxic to humans and could force closures of the bay if not addressed.

Rapid expansion of the urban core and agricultureRapid expansion of the urban core and agriculture
forces land to be repurposed, which damages hydrological connectivity and can waste precious groundwater resources.

The delicate balance of biodiversity could shift to the point where sports-fishing is a luxury more than a recreation, and the beautiful scenic environment is overrun with Phragmites, or locked down for conservation efforts.
Spotlight
A must-read report on climate change in Grand Traverse Bay:
The Watershed Center has been striving to protect the environment in the Grand Traverse Region since the early 2000’s. They advocate for clean water and high quality habitats through hands-on projects, and provide in-depth studies of watershed health. They are a member of the watershed alliance, a non-profit organization that represents over 300 organizations over 6 continents, and have constructed a strategic watershed management plan through to 2023.
In 2021, The Watershed Center also released a thorough watershed protection plan, detailing the current state of water quality, biodiversity and the environment. In this report, threats to the watershed were outlined, and suggestions for preparations, outreach and implementation of protection were provided.
Michigan has released a climate plan with directions to achieve carbon neutrality by 2050. Other goals include sustainable environmental management, conservation of resources and wildlife, as well as preparations for climate change threats.

The Michigan Department of Environment, Great Lakes and Energy has begun publishing biennial reports on overall water quality, including statistics on: Contaminants, effects on and from nearby watersheds and systems, as well as impending threats and suggested solutions.
