Grand Coulee Pastoral Charge was formed as a new United Church charge in 1925, as part of Regina Presbytery. Initially, the charge included preaching points at Grand Coulee and Sherwood. In 1948, the charge also added the Richardson preaching point. From 1968 until 1970, Grand Coulee was part of a six-point Pastoral Charge, with Pense, Drinkwater, Stoney Beach, Richardson and Sherwood. When this ended, Grand Coulee and Sherwood joined Wascana Pastoral Charge.

Around 1973, Grand Coulee re-established its own Pastoral Charge, and soon after these points joined with Pense, Drinkwater and Stoney Beach to form Pense - Grand Coulee Pastoral Charge. (Sherwood stayed in Wascana Pastoral Charge, eventually closing, June 30, 1990.) After the joint-charge was dissolved, Grand Coulee Pastoral Charge was re-established. In 1994, Grand Coulee and Pense-Drinkwater Pastoral Charges amalgamated, as Plainsview Pastoral Charge. The points at Pense and Drinkwater both formally closed on June 30, 1998, leaving Grand Coulee as the remaining congregation in the charge.
