TROA Overview • Truckee River Operating Agreement (TROA) • Signed in 2008 • Negotiated for nearly 30 years • Goals: – Improve operational flexibility – Improve efficiency of Truckee River Reservoirs – Improve instream flows – Satisfies water rights in conformance with existing decrees • Several parties in the system have the ability to: – Establish credit water storage – Exchange credit water – Trade credit water – Release water for beneficial use • Implemented December 1, 2015!

Operations and Accounting Model Model Simulation time Period ~ 1 Water Year Operational Forecasting Backward Looking Accounting Ops Start Day • Backward looking • One model, two purposes accounting mode • Specify Ops Start Date – Input PE and stream gage • Seamless transition from measurements – Model solves for inflows to backward looking reservoirs and reaches accounting to operational – Reconcile imperfect accounting forecasting in one model • Operational forecasting run mode • Run period stays the same – Forecasted inflows – Logic sets releases • RiverWare Accounting done – RiverWare simulates system in both modes August 23, 2016 RiverWare User Group Meeting

Operations and Accounting Model • Accounts – 870 total – 121 storage accounts • Supplies – 2207 total – 908 transfer supplies August 23, 2016 RiverWare User Group Meeting
Interagency Model Use • U.S. Water Master’s • Truckee Meadows Water Office Authority – Daily accounting – Short and long-term planning studies – Operational planning – Used to develop drought – Facilitate monthly process plan • USBR, Lahontan Basin • CA, Department of Water Area Office Resources – OCAP calculations (Truckee – Used to identify and Canal Operations) recommend TROA – Short-term planning exchanges and operations studies • Pyramid Lake Paiute Tribe – Forecasting for Newlands – Used for operational Project (TCID) planning/scheduling August 23, 2016 RiverWare User Group Meeting
Preparations for Implementation • Mock TROA Exercises • Table Top Exercises – Meeting with all TROA – Meet with USWM staff parties – 9 meetings in 2014 and – Met regularly since 2012 2015 – Discuss modeling of – Discuss and develop TROA accounting procedures – Practice and develop the – Provide training on monthly coordination model and supporting process with tool use hypothetical scenarios August 23, 2016 RiverWare User Group Meeting
Daily Accounting • TROA requires a daily • TROA allows for many accounting of the combinations of complex reservoir releases and operations : storage – Exchanges • Accounting drives – Holdbacks (credit water establishment) operations – Exchanges to meet • Extensive real-time data minimum flows needs (HDB) – Exchanges to – Reservoir elevations and maintain/balance reservoir releases storage levels – Stream gage readings – Releases of stored water to – Diversion data meet various demands – Etc.

TROA Data Framework August 23, 2016 RiverWare User Group Meeting
Accounting Dashboard August 23, 2016 RiverWare User Group Meeting
Scripts • Enable semi-technical users to: – Step the Ops Start Date forward – Override release allocations – Clear out inputs from model – Set short-term forecast parameters – Generate reports – Etc. • Several scripts used to streamline daily process August 23, 2016 RiverWare User Group Meeting
Online Reports • Built-in RiverWare Reporting • Group plots and tables • Used to meet TROA’s reporting requirements – Three reports published to web daily, directly from RiverWare – Referenced by parties for daily accounting information August 23, 2016 RiverWare User Group Meeting
