Recovery interpretation
More water is leaving below the dam than the Lake Michie watershed is bringing in (about -1.2 cfs net), suggesting the reservoir is drawing down.
Estimate only. Net surface flow (inflow − outflow) excludes municipal withdrawals, smaller tributaries, direct rainfall, evaporation, groundwater exchange, and travel-time between gauges. It is not an exact reservoir water balance.
