This prep volleyball season will feature a five-team race to the top in the Greater Columbia 1B League.

The conference adds Lyle/Wishram to the mix in 2010, giving it another team to compete for the Yakima Valley District's single WIAA Class 1B tournament berth. (Lyle/Wishram was in Class 2B prior to the last WIAA reclassifications, which take effect this fall.)
