So. By Thursday we are supposed to have 5 inches of rain, and by the weekend 10 inches.. And 40 mph gusts! From genius planning, the run has a slight slope into the stall.. Meaning the water floods the stall, but I build up a lump of bedding in the front of the stall to divert the water out of the run, which helps lots. The stall front is completely open out to the run (no wall). Casey's dry lot is way better drained than her stall area, but only has a thin tree canopy for shelter... This is supposed to be record amount of rain (in this short period of time)! Pretty amazing isn't it... We are supposed to have severe flooding.
I don't know if this is possible (if the ground is paved or natural) but you can perhaps dig a trench across the area that may flood and angle it such that it will divert the water off? We used to do that when camping and a rain was coming, we took our spoons out and dug a shallow (3 inch wide and deep) trench angled with the slope of the ground and it carried a lot of the water away.
But 5 inches of rain is pretty amazing. Where in US are you?
West coast tinyliny. That is not normal, and it has barely rained at all this winter.. Pretty nice weather! And yes, just up the a hill we have a three inch ditch and that helps, and, Casey always seems to fill in the ditches, but I will probably dig one in her pen in front of her stall. Thanks!
