In 1966, Blue Creek, from Paulding County and now a part of the Wayne Trace School District, joined the conference.

Blue Creek became a part of the new Wayne Trace School District, along with Grover Hill and Payne.

[2] Holgate announced in late 2019 that they would move to 8-man football due to low numbers, which caused the remaining schools in the Green Meadows Conference to vote them out of the GMC over scheduling concerns.

With Holgate's departure, the GMC decided to extend an invitation to former member Paulding in February 2020, which was accepted shortly afterwards.
