Most of the water of the park flows west to Lake Winnipeg. Although the vast majority of the park's land is located east of 95° 46' W, there are three very long thin corridors of parkland along streams that flow westward toward Lake Winnipeg. These streams are the Pigeon River, the Leyond River, and the Bloodvein River. The lakes and rivers are warmer than most rivers that are fed by cold mountain streams. The majority of the population north and east of the park are First Nations and the closest town is Bloodvein at the mouth of the Bloodvein River.
Atikaki Park was initially to become a National Park but ended up as a Provincial Park. The park was partially mapped out by Marc Wermager. No logging roads, logging areas, or major developments are allowed in the park.
