Thank you all for your help. I did the route with a partner starting last Sunday. We ended up taking an extra day to make the last few days more relaxed, resulting in a 7.5 day trip. We were very fortunate as there was just enough rain on March 26 to fill most small potholes in the area with water, but leave the roads untouched. I assume this water will last for another week or two, but it is starting to get hot, so this may not be the case everywhere. Unfortunately, since we did not use the large potholes near "Cliff", I am not able to report on how they are doing, but otherwise, we found at least some water in every large and medium pothole Allen mentions in the text. I wish I knew how long it will last. As Allen mentions, there is no water on the hike up to cliff or the escalante rim heading to Fool's canyon (no potholes). As for the road, my 2010 Honda Civic had absolutely no issues getting to the water tank on Fortymile. I would not recommend it, but would not be too surprised if it would have made it to the end of the road. I am thinking of making a trip report with some beta we would have found useful, will try to post soon. Happy trails!
