The minimum level

This article collects some information about the maximum level of Lake Constance.

Daily average values as a basis. In contrast to the maximum, the minimum is determined based on daily average values. In my opinion, this is not entirely consistent. At this point we are following the LUBW approach.

Lowest water level. For the years 1888 to 2023, the lowest water level was 229 cm. This level was reached on February 13, 14 and 15, 2006.

Contribution of different years to the minimum. If you look at which years contributed to the minimum of the level, the distribution below results. With 35 days, the year 1999 dominates as the year that has the maximum level for the longest period, followed by 2021 with 33 days. It should be noted that the sum of the days here is more than 365. In fact, the table returns 376 days. This is because several years can share a maximum value.

In chronological order, the following years contribute to the minimum:

1891, 1909, 1921, 1934, 1947, 1949, 1959, 1962, 1963, 1972, 1976, 1996, 2003, 2005, 2006, 2011

Minimum per day

The table below shows the minimum level for each day of the year (mm_dd format). February 29th is excluded. The year or years in which this minimum was reached is also stated. At this point, the minimum is also based on daily average values.
