Surprised Fiddler didn't beat me to it.
The best and safest area, IMHO is the northernmost, though the satellite view may not suggest that.
You'll likely find it smoother than your local paved field. Less offroad traffic, though there is some.
There are wind socks at the properties just outside the (north) western shoreline and at the landsailing cove along the south shore.
Of course, any offroad vehicles' dust does that job well.
Down the race course, along the lakebed's length, is maintained by the land speed community, but they (we) have been fighting with some erosion ditches that have formed out of the north. I'm not certain their current state of repair. One can see these with a simple flyover though. I may just land parallel and a little south of the course.
Beware of rougher conditions and crossing power lines on the (south) east end.
