(3) All the small reservoirs with conservation pools were started at full supply level, while all other reservoirs were started empty in the modelling exercise.

(4) The reservoir was started empty in the modelling exercise.

(5) Estimated from frequency analysis of instantaneous peaks recorded and estimated at the South Tobacco Creek near Miami WSC hydrometric station (050F017) (from Table 5)
