In the present paper results of estimating the time of immersion are presented by applying this table on 73 bodies with known postmortem interval. Since comparing the average monthly water temperatures used in the table, the actual water temperatures have risen during the last 40 years. Especially in summer, reliable results can only be expected when the actual water temperature is similar to the temperatures in the table. Especially for higher water temperatures, the time interval of immersion may be underestimated when using the table since systematic observations on the progression of putrefaction in correlation to the risen water temperature are missing. Therefore the table should be adapted to the risen water temperatures.
