    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

    • Deduru Oya at Moragaswewa is 17.2 ft, rising (at alert level)
    • 89 mm of rain in the last 24 hours

    Official flood map

    None of the Grama Niladhari divisions around Anamaduwa is in the Irrigation Department's maps of past floods on the Deduru Oya (2018). Low spots can still flood.

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