The silver anniversary celebration for the Lewis and Clark Regional Water System was held during the System's annual membership meeting in Tea, South Dakota. Nearly 130 people from all phases of the System's 25-year history attended the celebration.

Lewis and Clark Regional Water System holds several notable places in Reclamation history to include service area and volume of water delivered.

The project, located in south­east South Dakota, Minnesota, and Iowa, is the first Reclamation funded project to deliver water outside of Reclamation's 17 Western United States.

At 23.5 million gallons of water per day (MGD), Lewis and Clark Regional Water System is the largest, by volume, rural water system that has been authorized by Congress, and for which Reclamation is responsible for oversight.

Lewis and Clark started as the Southeast South Dakota Water Supply System in April 1990, with anticipated service to 27 communities and 16 rural water systems. This 72-MGD system had an estimated cost of $500-million.

A few years later, Lewis and Clark Rural Water System had a new name, and had 47 members. The system anticipated withdrawing water from Lewis & Clark Lake and treating raw water at four treatment plants spread throughout the system at a cost of $660-million.

By the time the project was authorized in 2000, Lewis and Clark had been reformulated to a 23.5-MGD system of 22 members. The system was designed to withdraw water from the aquifers downstream of Gavins Point Dam south of Vermillion, South Dakota.

In August of 2003, the first official construction using federal funding began, and in August 2012, a ribbon cutting ceremony was held for the beginning of operations at the system's water treatment plant.

When completed, the system will eventually serve more than 300,000 people in South Dakota, Minnesota, and Iowa.

The project has a Federal/non-Federal cost share of 80/20 percent, respectively. Lewis and Clark will have received $102-million in Federal funds and most of its non-Federal funds, with expected completion in 2025.
