One of the features of the reservation was Camp Chaparral, a combination school and camp where Yakima children were taught by both Native Yakima and people from outside the reservation. One of these teachers was Bonnie Tracy, the daughter of Dick Tracy.
The Yakima Reservation had its own police force under the supervision of Police Chief Proud. They also liaised with the local non-reservation police, including Detective Joe Sampson, who was himself a full-blooded Yakima.
The Yakima Reservation is where the fugitive musician Bony fled with his girlfriend Claudine. It was there that they encountered Vitamin Flintheart and Tess Tracy, who was eight months pregnant with her second child. Joe Tracy was born on the Reservation.
