Paw Paw Lake Foundation launches Biochar Initiative to combat pollution

The Paw Paw Lake Foundation is taking a major step toward improving the water quality of Paw Paw Lake with the launch of its new Biochar Initiative, a multi-year program aimed at reducing pollution and restoring clarity to the lake.

For the past two years, the Foundation has focused on halting chemical pollutants and farm runoff entering the lake. Now, the effort shifts to removing existing contaminants with biochar— a natural, chemical-free carbon material known for filtering water.

“The participation of all Paw Paw Lake residents is critical to the success of this effort,” said Foundation leaders.

What is biochar?

Biochar is a charcoal-like substance used in water treatment. For Paw Paw Lake, it will be deployed to filter out phosphorus, nitrogen, and other undesirable materials that have built up over decades. The Foundation has selected TimberChar, an EPA-approved and organically certified biochar system produced by Eden Lakes.

TimberChar has proven effective in reducing algae blooms, improving clarity, and restoring water quality in lakes of similar size and condition.

When will residents see results?

According to the Foundation, noticeable improvements may begin within 6 to 12 months of deployment, with the most dramatic results typically appearing in the second year. The process requires some bags to be replaced each spring, but the spent material can be reused as a soil enhancer in gardens.

How it works

The TimberChar will arrive in porous bags, about the size of a small sandbag, which can be tied to pier pilings. Lake water flows through the material during the season, absorbing pollutants. The bags are installed as early as May and must be removed by October under state permit regulations. Once winter passes, residents can reinstall them with ease.

Community involvement needed

To ensure the program’s success, the Foundation is calling on every lakefront property owner to take part. Residents are asked to complete an authorization form on the Foundation’s website no later than Oct. 15, 2025.

The Foundation is also recruiting volunteer “block captains” to serve as points of contact for neighborhoods such as Bowes Landing, Pomona Point, Windermere Landing, and Lake Point Condos.

In addition, donations are being sought to cover costs, with the first year of the program estimated at $170,000. All contributions are tax-deductible.

Preserving Paw Paw Lake for generations to come

The Paw Paw Lake Foundation, a 501(c)(3) nonprofit, has long been dedicated to protecting and improving the lake’s ecosystem and watershed. With this initiative, the group hopes to set Paw Paw Lake on a course for long-term environmental health and recreational enjoyment.
