This last spring the sky really opened up and flooded the park (Shadow Rock) near my home. It’s a great park but unfortunately lies in a flood plain and if we get too much rainfall the river rises over its banks flood the park. This time the rains were exceptional and the water was so deep it covered the buildings and everything. Trust me there is a park somewhere below all that brown water. Problem is the waters which normally recede in a few weeks pretty much stayed as we got a succession of systems throughout the spring and summer months. In the early fall we even got hit with the remnants of Hurricanes Gustav and Ike! Ike alone dumped something like nine inches of water on the area.
So the bottom line was that the grass that was growing very nicely has been subjected to a very prolonged period of submersion. As a matter of fact six months worth if I remember correctly. All that water also was pretty dirty and it deposited a half inch layer of silt (see below) over everything. When things finally dried out in October of this year, the scene was not very encouraging. I am in the process of putting together a You Tube video that chronicles the aftermath. It poses the question as to the chances of grass re-growing this coming spring. I feel the park will need to be re-seeded while the city thinks it will recover on its own. Time will tell.
Note: I did dig under the covering of muck and was not able to find anything growing there. I also placed a chunk of dirt into a glass jar to see if I could discern some structure to it and was not able to. It is just a very uniform silt.
