It rises near the community of Preeceville in eastern
Saskatchewan and then southeastward to "The Forks" inWinnipeg, Manitoba where it flows into the Red River. Some of flood flows can be diverted intoLake Manitoba atPortage la Prairie . In 1967, the Shellmouth Dam was built in Shellmouth to help reduce flood peaks and to supplement flows during dry periods. ThePortage Diversion was completed in 1970. There are three hydrometric stations placed on the river that have been taking measurements since 1913.
