Rivers
CSENRiver levels — floods & drought
Water level and flow at 542 ČHMÚ stations — floods and drought on one map.
FAQ
Where does the river data come from?
From the ČHMÚ hydrological network — 542 gauging stations measure water level and flow roughly every 10 minutes. We show it over the precipitation radar.
What do the flood-activity degrees (SPA) mean?
1st degree is watchfulness, 2nd is alert and 3rd is danger. Each station has its own level and flow thresholds, which decide its colour.
Does the map also show drought?
Yes. When a level drops below a station’s drought threshold we colour it as drought, so you see floods and drought on a single map.
Does ČHMÚ monitor fishing spots or water temperature?
No. These are gauging profiles (level and flow), not fishing waters, and the feed has no water temperature. For anglers the flow is most useful — a high level means an unfishable river.
