RUNOFF JOURNEY
WHAT THIS MEANS
Reading the watershed…
This tracker watches Pecos River gauges from northern New Mexico downstream. A surge at an upstream gauge does not mean all of that water will reach Amistad; reservoirs, diversions, infiltration and evaporation can reduce or delay the pulse.
How to read the tracker
🟢 Runoff detected
Flow is elevated or rising at that point in the river.
🟡 Regulated / watching
Upstream water may be stored or released gradually through reservoirs.
⚪ Awaiting response
No clear downstream response has been detected yet.
River observations are provisional USGS data and subject to revision. Lake Amistad information is sourced from Water Data for Texas/TWDB, which notes that IBWC is the official repository for treaty-related reservoir data. This page is informational and does not provide flood warnings.
