With little evaporation and almost no transpiration from growing plants, the only way for water levels to drop is by percolation through the soil – either by artificial drainage or natural seepage through the soil.

Seepage this year with saturated soil from two months almost continuous rain is much slower than I have ever seen it. It’s noticeable that where conditions were good at sowing, there are few pools in fields but where conditions were less than good, it seems that some compaction has taken place which is impeding normal, natural drainage.
