, both major water reservoirs. Upstream of Dartmouth Dam, the river flows swiftly through near-pristine forest. Below the dam, it travels more sedately through flatter, cleared farming country.

The catchment area of the Mitta Mitta River is estimated as .
The river valley used to flood on a nearly annual basis, but the completion of Dartmouth Dam in the 1970s largely eliminated the floods.
