The water has left the system before if could be measured.

Explanation:

Some of the water has flowed quickly along as surface runoff and through the river channel. Scientists would then missed the chance to measure this rainfall. Some water will have been absorbed by nearby vegetation. The vegetation then releases the water in a vapor state, to the atmosphere. This process is known as transpiration. Heat in the atmosphere causes evaporation and the water never joins the soil of groundwater to be measured as part of the water table.
