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.

Regina Wascana Pastoral Charge was formed around 1932 (listed as vacant) but by 1936, the church was part of Regina Rosemont Pastoral Charge. Regina Wascana Pastoral Charge appears to have been re-formed as a joint charge with Rosemont, ca.1951, then as a separate charge, by 1953. Around 1970, preaching points were listed as Grand Coulee and Sherwood. Grand Coulee moved back into its own Pastoral Charge around 1973 but Sherwood remained until it closed, June 30, 1990. Wascana Pastoral Charge itself closed on September 30, 1996.
