Bigger pond

Has it stabilized, or is it still falling? It isn't a function of housing, I'm in a rural area where there isn't a whole lot of "housing." It's more a function of how very little rain we have had over the past few years. When we lived in Miami, we had water pretty near the surface. That was 22 yrs ago. There is a mixture of clay and sand here, overlaying the Hawthorne formation of limestone. That results in sort of two water tables. The main one is in the limestone, at a depth in this area a little below the Suwannee River, roughly about 80 feet above sea level in this area. That water table has been falling also, although not as fast. The upper table is in the poorly drained sand and clay, where it is over cracks in the limestone, it drains down into the aquifer, otherwise it pretty much stays around. That is the part that is so dry. We have gotten pretty used to saturated ground here. We don't really know how to behave now that it's so dry. -- Galen Hekhuis We'll cross that bridge when it rears its ugly head Yep. Sounds like a recipe for sinkhole formation. Keep your safety ropes handy. lol George |
