The streams converge near Neelin, Manitoba and flow initially northeast, then southeast along the west side of the Pembina Hills into Cavalier County in northeastern North Dakota.

The watershed is level through the central and eastern regions, however the elevation rises roughly 200 metres (660 ft) in the 25-kilometre (16 mi) radius around the Turtle Mountain Provincial Park.

Data from hydrometric stations are used to monitor river flow rates and lake levels, for flood forecasting, and water management investigations.

Information from this station is collected regularly and is used to analyze for numerous variables including pesticides, metals, nutrients, general chemistry, and bacteria.

Elevated phosphorus concentrations promote excessive algal bloom growth, which have many undesirable outcomes for the watershed and the entire Lake Winnipeg basin.
