Last 5 DaysiRiver level & rainfall — the blue line is the Glenderamackin's height at Threlkeld. The bars hanging from the top show rainfall in the river's upper catchment (Environment Agency gauge near Mungrisdale), so you can see the river rise in the hours after rain falls on the fells. Heavier, longer bars mean more rain.

Indicative only · Always check before you swim
Conditions are estimated from river levels, recent rainfall and EA annual classifications — not direct water testing.
They are not a substitute for checking on the day. After heavy rainfall, even good-rated lakes can have elevated E. coli from agricultural runoff. Never swim alone, be aware of cold water shock, and check for local restrictions. EA bathing water profiles ↗
