High volume releases of nutrient-rich, and blue-green algae laden water from Lake Okeechobee last summer led to massive algae blooms along the Caloosahatchee River, in Cape Coral canals, and in the river’s estuary. And this all happened as a prolonged red tide bloom persisted along the Southwest Florida coast. Now, three conservation groups are suing three federal agencies for what they say is a failure to address harm to Florida’s endangered species being caused by the releases.
