The Mississinewa Watershed extends from the Mississinewa River's confluence with the Wabash River near Peru, across Indiana in a generally southeastern direction and extending just over the border into Darke County, Ohio. It drains most of Grant County, large portions of Blackford County, Delaware County, and Randolph County, and parts of five other Indiana counties. The Mississinewa River has many tributaries, including Big Lick Creek, Grant Creek, Hummel Creek, Lugar Creek, and Mud Creek. The Mississinewa River is dammed a few miles upstream of the Wabash, thus forming the Mississinewa Reservoir.

As noted earlier, the Mississinewa River enters the Wabash River just upstream from Peru. The Wabash River flows into the Ohio River, which then joins the Mississippi River, ultimately emptying into the Gulf of Mexico.
The United States Geological Survey has assigned the Mississinewa Watershed an 8-Digit Hydrologic Unit Code of 05120103.
