What Today's Conditions (72°F • 577.5 ft) Mean

Boat Ramps & Navigation

At 577.5 ft MSL, main public concrete ramps remain fully functional with sufficient trailer draft. Boaters should exercise standard vigilance around shallow sandbars when straying outside marked navigation channels.

Private Docks & Shorelines

Water line is situated 0.5 ft below normal conservation pool. Floating docks and gangways are operating at optimal gangway slope without mud grounding.

Water Temperature & Recreation

Surface water temperature of 72°F provides brisk recreational conditions ideal for fishing and boating; early-season swimmers may prefer a shorty wetsuit. Safety status is currently rated CLEAR.

Copernicus Sentinel-2 MSI Telemetry

Spaceborne Satellite Observation & Water Clarity

Fresh multi-spectral overhead Earth observation from the European Space Agency (ESA) Sentinel-2 constellation (10m spatial resolution).

Copernicus Sentinel-2 true-color satellite capture of Lake Ouachita
True-Color Natural Optical Spectrum (RGB B04/B03/B02)
Resolution: 10m/px • Atmospheric correction L2A Open Full Imagery ↗

Satellite imagery and indices processed via Copernicus Data Space Ecosystem (CDSE) / Sentinel Hub API. Data reflects actual surface conditions at the time of orbital passage.

Water Clarity & TurbidityCrystal Clear (High Secchi Depth)

Derived from Band 4 red reflectance across open water pixels. Low reflectance indicates minimal suspended silt and high underwater visibility for angling and navigation.

Spaceborne Cyanobacteria / Algae RiskLow / Safe (Normal Chlorophyll-a)

Normalized Difference Chlorophyll Index (NDCI: 0.004) measures phytoplankton concentration using Red-Edge (B05) and Red (B04) bands to detect early bloom development before surface scums appear.

Shoreline & Emergent Island DelineationNDWI Active

Normalized Difference Water Index (NDWI) contrasts Green and Near-Infrared spectra to map shallow shoals, sandbars, and exposed islands (like Sometimes Island on Travis or Wood Island on Texoma).
