I was at El Mirage clean up day last Saturday (May 4th). While some deep ruts remain, I believe they could form up a clear course or 2. My buddy was sifting fill for the remaining ruts as part of his cleanup days tasking. I was picking trash. I was out on the lake bed a couple of weeks ago and I saw what looked like earth movers, graders and water trucks. Filling the ruts properly is important (very). I drove over some of the repaired spots, and they appear to be firm (good). Frankly if we had to, we probably could have made the May event, but you do not want to hit these ruts at any speed, even return road speeds. While they don't look that deep, the sharp edges will give your suspension fits.
