There has been no significant rain on our farm or in the watershed of our creek for 10 weeks. However, the water level in the creek has risen substantially!
We have sandy loam soils that transmit a lot of groundwater in the top 6-8' as springs. The tallgrass prairie has evolved roots that easily reach to that level.
When the grass goes dormant in the late fall, the water in the creek goes up as the groundwater flows can finally outpace the transpiration of the plants!
It is an impressive ecological system that has certainly adapted to survive pretty significant droughts.
