South Platte River Basin

Residents and interested parties are encouraged to participate in the Basin Implentation Plan process.  Please note that the South Platte and Metro basins produced a combined Basin Implementation Plan.  Contact your basin roundtable for ways to get involved in the Basin Roundtable process.

Please note that the information provided below on the South Platte and Metro BIP is identical since both Roundtables are working together to produce one combined BIP.

The South Platte Basin Roundtable covers approximately 22,000 square miles in northeast Colorado. The largest cities in the roundtable area are Boulder, Fort Collins, Longmont and Greeley. The projected population in 2050 is estimated to almost double in size to between 1.9 and 2.6 million people.

Nearly two-thirds of the increase in the state gross municipal and industrial (M&I) demand by 2030 – or approximately 324,000 acre feet (AF) to 467,000 AF with passive conservation included – will be in the overall South Platte Basin (a combination of the South Platte Basin Roundtable and the Metro Roundtable areas).
