I think they are running a little more water down Crab Creek below Billy Clapp. I heard that two days ago. Who know's how high the creek will rise once Crab Creek gets it's full amount of water in 2017.
Crab Creek feeds the eastern arm of Moses Lake. Rocky Ford feeds the western arm. The underground rocks are fractured so much that groundwater can seep from Crab Creek, which is above and along RF, to the area that RF emerges from. The more water that runs thru Crab Creek allows more water to seep over to RF.
