Lake Erie/HABs
The Lake Erie and Harmful Algal Blooms (HABs) subnetwork is a group of organizations committed to working together to restore the health of Lake Erie so that it provides safe drinking water, quality recreational opportunities, and supports vibrant communities and sustainable economies.
Our mission is to weave together natural and human communities, advocating for the Rights of Rivers and their Ecosystems.
