Cumulative Natural Inflow to Water Storages
The Historic inflow comparison shows total reservoir inflow for every season since 1950, compared with the historic average inflow, and Post-1997 average inflow. (Note: for reservoirs constructed after 1950, inflow is simulated for the period prior to construction)
The Reservoir system performance graph provides a summary of total inflow, outflow and evaporation loss from each reservoir for the previous water year.
