the only reason that wixom lake was filled with water was because the AG mandated that it be filled.
No, she didn't.
The AG sued them to punish them for lowering the lake level IN PREVIOUS YEARS, WITHOUT GETTING NECESSARY PERMITS.
"This lawsuit seeks to vindicate the rights o fthe public to enjoy and benefit from Michigan's natural resources, including the freshwater mussels that live in the Wixom Lake ecosystem in Gladwin and Midland Counties.
Without authorization, Defendants dramatically lowered the level of Wixom Lake for an extended period
in both 2018 and 2019 (Drawdowns), causing the death of thousands if not millions of freshwater mussels-many of which are federally endangered. The Drawdowns also unreasonably dewatered wetlands that depend on Wixom Lake and otherwise damaged Michigan's natural resources. This suit seeks monetary relief and civil fines to compensate the public for the damage caused to the public's natural resources, and equitable and prospective relief to restore the natural resource damage and to ensure that it does not happen again."
It did not force them to do anything in 2020.
They could have gotten appropriate permits and lowered lake levels. They could have lowered lake levels, and potentially gotten fined again. They could have fixed their dams and not worried about lake levels.
... but they were absolutely NOT forced to fill Wixom lake by the state.
