Current discharge at the inflow and outflow stations included here. Their difference is a partial balance, not a measure of the entire lake.

-0.05 million m³/dayThat's roughly 19 Olympic swimming pools per day.

How to read the water balance: the difference compares only the inflows and outflows recorded here, in cubic metres per second. A positive value means these stations record more inflow than outflow; a negative value means the opposite. Not all tributaries are included, and rain on the lake, evaporation and groundwater are also missing. This value alone therefore shows neither the lake's full volume change nor a reliable water-level trend.

Rain and inflow

How Aabach, Mönchaltorf (Zufluss) responds to rainfall over the last 30 days.

  • Rain
  • Aabach, Mönchaltorf (Zufluss)

How to read: the bars show daily precipitation in the catchment (mm, left axis), the line the largest measured tributary (right axis). This shows whether and how quickly the lake responds to rain – inflow usually follows precipitation with some delay.
