OUR WATERSHED

Seven lakes. Three cities. One watershed.

Everything that flows over the land in Orono, Long Lake, and Medina eventually ends up in Long Lake — and from there, into Lake Minnetonka and Minnehaha Creek.

The Long Lake Creek Watershed is the headwater for Lake Minnetonka and Minnehaha Creek. That means the choices made on lawns, driveways, and farm fields miles from the shoreline shape the water clarity, fish health, and recreation we all enjoy.

Long Lake is currently listed as water-quality impaired — but the science is clear, the partnerships are in place, and the path forward is real. Our work, and the work of our partners at the MCWD, is designed at the scale of the entire watershed.

KNOW THE BOUNDARIES

The Long Lake Creek Watershed

Seven lakes — School, Holy Name, Wolsfeld, Dicky's, Lydiard, Long, and Tanager — connected by streams and wetlands across Orono, Medina, and Long Lake. Every drop of rain and snowmelt within these boundaries flows toward Long Lake.

WHY IT MATTERS

The watershed is the work.

Algae blooms, lost water clarity, and impaired fisheries don't start at the shoreline — they start with what flows across the land. Restoring Long Lake means restoring the whole 7,619-acre watershed that drains into it.

OUR PARTNER

Minnehaha Creek Watershed District

The MCWD is the regulatory and planning authority for our watershed. Their Long Lake Creek Watershed Roadmap lays out a multi-year, science-driven plan to restore water quality — and LLWA is proud to be a community partner in that effort.
