What attracted you to FLOW?:A few years ago, I had the privilege of interviewing David and Jodi Archambault, brother and sister leaders of the Dakota Access Pipeline protests at the Standing Rock Sioux reservation. Dave and I visited the Sacred Stone encampment site along the Cannonball River, where the family kayaks in the summer, near the place where the pipeline runs under the Missouri River – water essential to the tribe’s history and future survival. We talked about the spiritual importance of water and being good ancestors. Talking to FLOW staff reminded me of that conversation. I thought, “They get it.”

Your favorite fact about the Great Lakes: I’m blown away that there are shipwrecks in the Great Lakes that have never been recovered, and century old wrecks still being found. It makes me want to abandon everything and join a salvage crew – but without the sketchy submersibles.

What connected you to the Great Lakes: Polling a home-made raft with my brothers up and down the shore of the East Arm of Grand Traverse Bay. I was fortunate that my parents moved their family—two girls, three boys—to Traverse City, by the time I was 5 years old we lived on the Bay, so, we grew up in and on the bay, felt its cold and warm temperatures, sensed its sweetwater smell, moods, its seasons and cycles, seches’ that flooded the beach, tore out docks, flipped over moored boats, ice skating, fishing, watersports, dressing up like pirates and pushing each other off row boats into the water.

Favorite place in Michigan: There are so many places that are “favorites,” it’s hard to say—Michigan’s beauty is soft, gentle, rough, rugged, and diverse from the ends of both peninsulas to the other ends. A few places-- Cathead Point, Lake Michigan’s Dunes, and vistas from the worn down mountains, cliffs and beaches that rim Marquette and Lake Superior.

Favorite Great Lakes fact: The distance from the border of southeastern Michigan to Ironwood and Michigan's border with Wisconsin in the Upper Peninsula is almost 650 miles--an 11-hour drive! Perhaps, longer than any distance within any state in the lower forty-eight! With lots of shoreline, rivers, lakes, creeks, wetlands, wildlife, pastures, farms, hills, and ridges, Great Lakes shoreline all the way.

What attracted you to FLOW? The most significant factor that attracted me to FLOW was its mission and vision. Access to clean and safe drinking water is an undeniable human right, and FLOW takes charge to ensure our lawmakers are held accountable for delivering on their promise to protect and preserve our waters. As the Policy Director, I will be able to give a voice to water and live up to my name, Giziibii Ogitchida’ikwe (River Chief Woman).

What connects you to the Great Lakes? As an Indigenous woman, water is part of my identity. The Great Lakes hold a special place in my heart as they serve as a connection to my ancestors and their legacy. This is the same water that flowed through their bodies and it is the same water that rained upon their heads, as it does mine. The water that I touch today will be the same water that future generations will touch. As long as we cherish and protect it, water will serve as a powerful link between our past and future, uniting us all in its precious embrace.

Favorite place in Michigan:My favorite place in this world is a little creek that runs on my parent's property deep in the woods. When I need to quiet the world around me, I go to this place where I can talk to my grandmother, listen to the water running across the rocks, and find peace within myself.
