Every observation keeps its station, parameter code, unit, timestamp, qualifier, approval state, datum, and official source link.

Trustworthy by design
Understand what the gauge represents
Relationship cards explain whether a station is on, near, upstream, downstream, or otherwise related to the waterbody.
Set your own threshold
Choose high, low, or daily alerts. Hysteresis and idempotent delivery prevent noisy sensors from producing repeat notifications.
Browse by water type
Start with the water you care about
Directories only include pages with useful monitoring coverage and explainable relationships.
A humble “Now”
Stale data never masquerades as current
If a source is late or unavailable, the last known observation stays visible with its real timestamp and a stale label. LakeRiverNow never fills a gap with an estimate.
How freshness worksCome back to what matters
Set a water alert, then let the gauge watch for you.
Free accounts can save waters and receive a limited daily email. Plus adds more locations, custom thresholds, faster cadence, and longer comparisons.
Important limitation
Readings do not establish safety
A water level or gauge reading alone cannot determine swimming safety, navigability, ice safety, drinking-water safety, dam safety, or the absence of hazards.
