Details

How this estimate works

  • · Starts from the river gauge's own level and forecast, the same as the gauge page.
  • · Heavy rain here (50 mm in 6 hours or 100 mm in 24 hours) raises it by one step, never more.
  • · Your own street level, if you set one, and official warnings can raise it further.
  • · It never says flooding is happening: only a measurement can show that.

Why

  • Irrigation Department has issued a flood warning for Kelani Ganga
  • Kelani Ganga at Norwood is 5.9 ft, falling (at alert level)
  • 55 mm of rain in the last 24 hours

Official flood map

None of the Grama Niladhari divisions around Hatton is in the Irrigation Department's maps of past floods on the Kelani Ganga (2016 major flood, 2012 minor flood, 1989 critical flood). Low spots can still flood.

This shows where a past flood reached, not a flood now. A bigger flood can go further.
