Josephine Mandamin, a well-known environmental activist from Wikwemikong First Nation in Ontario, died Friday morning, she was 77.

In 2003, Mandamin co-founded Mother Earth Water Walk after being concerned about the pollution of rivers and lakes. She took that concern for a walk - for a total of more than 17,000 km circumnavigating the shores of all five Great Lakes.

Her words carry true today, Mandamin stated, "As women, we are carriers of the water. We carry life for the people. So when we carry that water, we are telling people that we will go any lengths for the water. We'll probably even give our lives for the water if we have to."

Mandamin leaves behind her husband, eight children, 13 grandchildren and 16 great-grandchildren. She was the great-aunt of youth activist Autumn Peltier, who also campaigns for water protection.

In 2016, Madamin and the Water Walks group received the Lieutenant Governor's Ontario Heritage Award for Excellence in Conservation. She also served as the head of the Anishinabek Women's Water Commission.

Her water walks story can be found in the children's book called 'The Water Walker' by Joanne Robertson, published in 2017.

"We have lost a great advocate, teacher, and role model," said Glen Hare, Grand Chief of the Anishinabek Nation, of which Wikwemikong is a member.

Hare added, "She will be so deeply missed by all and will be fondly remembered for all of what she did to protect the water."

In a statement issued Friday, Carolyn Bennett, minister of Crown-Indigenous Relations said Mandamin "taught all of us of the fragility of water, and the risks that exist to the health and sustainability of our waterways."

"The important work she started through Mother Earth Water Walk and the Great Lakes Guardians' Council lays the foundation for the future of the Great Lakes Waterways, and for the next seven generations of water walkers and water warriors from across Turtle Island," she said.

"She has touched many of our lives and we are truly grateful to have gained knowledge and wisdom from this inspirational woman and her life's work."

Mandamin's funeral took place Monday in Wikwemikong First Nation.
