The hydrologic condition analysis for the 2020 Basin Plan Evaluation drew on data of estimated flows derived from hydrologic modelling done during the development of the Basin Plan 2012. The specific data used for the Evaluation was derived from Basin Plan Model Run 845 which was an earlier version of the final model run (Basin Plan Model Run 871) which was used to establish the Baseline (BDLs) and Sustainable Diversion Limits (SDLs) for the Basin Plan.
