River Water and Rainfall Levels in Harborough District – Gauge Locations

River Levels

  • The Environment Agency measures river height from:
    • A fixed point near the riverbed (local datum)
    • Average sea level (ordnance datum, shown as mAOD)

Why Levels Can Be 0 or Below

  • Riverbeds change with erosion or silt, but this doesn’t affect accuracy.

How Forecasts Work

  • Computer models use:
    • Rainfall and river data
    • Rainfall and tidal forecasts
  • Models can be less accurate for small rivers or if data is wrong.
  • These forecasts are not checked by experts, unlike flood warnings.
  • Always check flood warnings if concerned - Flood alerts and warnings - GOV.UK

Why Flood Warnings Differ

  • Flood warnings may show different levels because experts adjust the model.

Sea and Groundwater

  • Tide and groundwater are measured in metres above average sea level (mAOD).

Updates

  • Levels update:
    • Once or twice daily when risk is low
    • More often when flood risk rises

What “Low,” “Normal,” and “High” Mean

  • Based on past data:
    • Low = below normal
    • Normal = within normal range
    • High = above normal
