After nearly three decades of negotiation and preparations, the Truckee River Operating Agreement (TROA) has been enacted in the Truckee basin in California and Nevada. Precision, in association with the TROA Planning Office, has been developing the technical tools for over 10 years that are to be used to implement the historic agreement. The TROA Administrators Office is tasked with implementing TROA and Precision is working with the Administrator to coordinate scheduling, backward-looking accounting, operations, forecasting, and coordination with all of the TROA parties.
