Gauge sits below the Little River Tributary confluence, so readings include tributary flow (not pure dam release) and are often suppressed by USGS as backwater-affected.

Reservoir elevation

Daily snapshots of the City of Durham's published elevation, stored by this dashboard. Points before 2026-07-19 were digitized from the City's 30-day chart image (±0.3 ft) and are excluded from trend calculations. Provisional.

Source: Weather Underground personal weather stations (hobbyist gauges near or upstream of the reservoir — accuracy and siting vary). Daily totals reset at local midnight; today's bar is rain so far. Today's value is the mean across reporting stations.

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.
