I live on the very edge of a Zone A flood plain - yup have that expensive FEMA flood insurance. We are just 2 blocks from the main stream channel of Big Creek - i.e. in our location the city's lake that has a very old dam.
In the past the lake has been relatively full - 3 and 4 years ago the lake was extremely full; now its virtually empty, except down by the dam. Three/four years ago, out west experienced a lot of rain as well as the watershed between WaKeeney and here resulting in an over-abundance of water.
Fortunately, I had a new sump pump installed when I purchased this house 7 years ago. During the winter months, I learned that when the vegetation - mainly trees - cease to need water, the water from the fullish lake seeps somewhere as the ground is porous and it is usually not frozen down that far. So anyone that has a basement/cellar in the vicinity of the lake, needs a sump pump.

In the spring, when the trees and vegetation with deep roots start their annual "wake-up", they start soaking up the water that is seeping through the ground from the lake; and, this continues all summer in to the fall time. Once again the water has to go somewhere.
If one has a basement/cellar, unless you have put waterproofing means around your walls, the water is going to come in through those walls - mine are large limestone rock squares that has had cement applied to the surface.

Three and four years ago, I experienced a constantly flooded cellar in the winter months. I could see the water coming through the walls and bubbling up through cracks in the floor. If those 2 appliances hadn't been up on blocks, they would have had 1-2 inches of water inside them. And, since they were up on blocks when I bought the house, the cellar has obviously been flooded in the past too.
|Cleaned out and checked - it works! Isn't this exciting?|
Yes, there have been two major floodings - the last one in 1993 and one in 1957. Do you suppose . . . .
