Source Ledger
Data sources and expansion candidates
LakeStat separates observed measurements from metadata-only catalog records. National coverage uses official metadata first, then promotes lakes to observed status only when a reliable agency feed is normalized.

Observed and planned feeds.
| Source | Status | Coverage | Latest run | Items | Cadence |
|---|---|---|---|---|---|
| USBR RISEusbr-rise | planned | Reclamation-managed reservoir levels, storage, releases, and related time series. | not-run | 0 | Site and parameter dependent. |
| EPA WQPepa-wqp | planned | Discrete physical, chemical, biological, and habitat observations where lake monitoring exists. | planned | 0 | Agency-dependent. |
| LakeStatlakestat-generated-assets | active | Self-created fallback lake cards for lakes without verified photographs. | not-run | 0 | manual |
| LCRAlcra-highland-lakes | active | Highland Lakes operating context, lake-level reports, projections, and historical files. | available | 6 | LCRA publishes current reports and periodic projection/history files. |
| NWSnws-alerts | active | Active official weather alerts around lake coordinates. | planned | 0 | As published by NWS; LakeStat checks on request for the selected location. |
| NOAA NWMnoaa-nwm | planned | Modeled hydrologic forecast context, including reservoir-aware configurations. | planned | 0 | Model-cycle dependent. |
| NOAA NWPSnoaa-nwps | planned | Forecast points, flood categories, hydrographs, and warning context. | not-run | 0 | Forecast-cycle dependent. |
| RIDBrecreation-ridb | planned | Federally managed recreation areas, facilities, and activities. | planned | 0 | As published by Recreation.gov partners. |
| State portalsstate-water-portals | planned | State-run reservoir dashboards, public health advisories, boat ramp notices, park closures, and GIS lake inventories. | not-run | 0 | State and program dependent. |
| USACE CWMSusace-cwms | planned | Corps-managed reservoir time series where public CWMS offices expose data. | planned | 0 | Office-dependent. |
| NIDusace-nid | active | United States dam inventory records with storage, location, purpose, ownership, and public safety metadata. | success | 1000 | USACE published inventory updates; not a live lake-status feed. |

| USGS IVusgs-nwis-iv | active | Historical backfill for mapped USGS lake and reservoir gages using instantaneous-value parameters 00065 and 00010. | success | 58760 | Historical backfill on demand; current values refresh near-real-time where active sites publish observations. |
| USGSusgs-waterdata | planned | Monitoring locations, continuous values, daily values, and time-series metadata. | planned | 0 | Near real-time or daily depending on monitoring location. |
| TWDBtwdb-reservoirs | active | Texas monitored reservoirs with recent storage, level, percent-full, and capacity fields. | success | 1830 | Daily when TWDB updates the public reservoir feed. |
