Region C and Region D 2016 Plan Interregional Conflict

On October 5, 2015, representatives of the two regions met in mediation and discussed the issues related to the current conflict in their 2016 regional water plans relating to the Marvin Nichols Reservoir. Region C and D agreed to resolve the conflict between their IPPs through four points of agreement
