We rafted the top half of the Canyon in May. The water was high and fast due to significant releases from Lake Powell that were being made with a view to increasing the water level at Lake Meade. It is good news indeed that it is expected that the level at Lake Powell will be much higher notwithstanding those releases.
The constant re-balancing Mead and Powell—along with the dozens of other reservoirs throughout the whole drainage—has worked well.
