Recovery interpretation
Flows are monitored for Little River Reservoir, but its downstream gauge includes tributary flow, so direction is only reported from measured lake elevation.
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.
