Who we are

The Riley Purgatory Bluff Creek Watershed District (RPBCWD) is a local, special unit of government with a boundary based on the watersheds of Riley, Purgatory, and Bluff creeks. It was established on July 31, 1969, following a petition by local property owners to the Minnesota Water Resources Board. The purpose of RPBCWD is to protect and improve the water resources of our communities.

Where we're located

The boundary of the watershed district is based on the watersheds of the three creeks. The boundary encompasses portions of seven communities including Eden Prairie, Chanhassen, Minnetonka, Bloomington, Deephaven, Shorewood, and Chaska. The district office is located at the border of Chanhassen and Eden Prairie near Dell Road.

What we do

When it rains, water that falls on the landscape drains toward a waterbody. This area of land is the body’s watershed. Anything that happens within a watershed impacts the lake, creek, wetland, pond, or aquifer it feeds. Watershed districts are charged with protecting and improving our communities’ water resources. Districts partner with local communities to identify top priorities and plan, implement, and manage efforts which protect and improve local water resources. They educate and engage residents, and the work they undertake benefits the quality and quantity of water in local as well as downstream watersheds and communities.

Watershed Management Plan (10-Year Plan)

The Watershed Management Plan is a document that guides all of the watershed district’s actions. The plan undergoes an update every 10 years and highlights how the district will monitor local water quality, the projects it will do, and how it will engage its community.
