How to read this

Stations are ordered from north (top) to south (bottom). The dashed line marks Guana Dam, which separates Guana Lake above from Guana River below.

Future live data

Real-time conditions from NOAA CDMO datasonde stations can be added here after publication.

Ponds, channels, lakes & rivers

USGS 3DHP hydrography within the Guana area. Zoom and pan to inspect mapped ponds and marsh channels. Monitoring stations are shown for orientation.

Waterbodies Flowlines / channels Monitoring stations

Important: A mapped channel is not automatically a safe or navigable kayak route, and a mapped pond is not automatically confirmed alligator habitat. Guana Guide field notes can be added as a separate curated layer later.

About the data

Water quality: Florida SEACAR Program 5014, Guana River and Guana Lake Water Quality Monitoring.

Plankton: NOAA Phytoplankton Monitoring Network observations.

Map: U.S. Geological Survey 3D Hydrography Program (3DHP), stored locally as GeoJSON.

Future: GTM NERR SWMP/CDMO regional comparison and near-real-time telemetry can be added later without changing the dashboard structure.
