The area around Deadhorse, Alaska (Prudhoe Bay) is technically a desert with an average yearly precipitation of 153 mm. A desert is anything below 250 mm a year. But just look at the map surrounding it - there's thousands of lakes: https://www.google.com/maps/place/Prudhoe+Bay,+AK https://www.google.com/maps/place/Prudhoe+Bay,+AK Lakes are supported from below by a thick layer of permafrost which is completely unpenetrable to liquid water. Combined with low evaportation - it is one of the most moist pieces of land on the planet. And a desert at that :)
