Ground Water Ski Lake - 10/30/18 04:13 AM
Hello all. I'm in Utah and considering developement of a ski/wakeboard lake community. Nutshell version... about 60 acre property just outside a small metro area of 130k population. Parcel is 2450ft wide, so just wide enough. I plan on two lakes with a peninsula between them. About 28 build lots between the lakes and another 45 around the outside.
Land is very flat. Currently farmland used for dairy farm crop and grazing. Not sure of soil content yet, but one thing is certain. The water table even now in late fall is very high. We haven't had appreciable rain for about 3 months and there are a couple low watering areas (about 3ft below grade)for the cattle that have standing water. There is also an irrigation canal running the perimeter of the property and the land comes with generous water shares if ever needed.
My questions are around a ground water lake. I would prefer not to have the lake level fluctuating +-36in depending on snowfall, because I want to maintain 16:1 grade at edges to prevent erosion. These are to be wakeboard compatible lakes at about 10ft center depth. I know the moment I hit about 3ft depth things are gonna start to fill up.
Even if clay content isn't quite high enough, sodium bentonite is mined nearby,and the economics of the developemnt can handle an application of as much as 5 lbs/sf to seal up the lakes. We can then divert from canal to maintain desired water level. But will the bottom of the lakes seal correctly with clay or bentonite given the fluctuating water table?
Thanks!
