August Rainsaster
The predicted October-like storm, with potential for record-setting low pressure for this time of year, unleashed the greatly feared torrents of flash flooding rain on us yesterday.
It revealed several areas where we need to improve our water management if we hope to withstand the ongoing onslaught of gully-washing downpour events that keep happening with increasing frequency.
When I got home from work and went outside to check on things, there was 4.5 inches of water in the rain gauge. I knew from that amount that the round pen would not have fared well for losing sand, so was prepared for the worst.
In spite of the heartbreaking mess of runoff sand, it wasn’t as bad as I had feared. I could see where some of the worst spots were for the water running into the round pen, and quickly went to work with a shovel to dig channels for draining water around, instead of through.
I also dug several pathways to encourage water to more quickly flow out of the paddocks, before it pooled up and drained toward the round pen.

Back up at the barn, where our gutter upgrade has yet to happen, the old system was failing brilliantly. I needed to pull the downspout to clear an obstruction, soaking myself in the process, and then discovered fixing that just transferred the overflow to the bottom where the downspout enters the buried drain tube. Something, either the recent dump truck activity or simple horse traffic, appears to have impeded the flow down the buried tube. That will be a doozy to fix.
While walking down to check whether anything was flowing out of the bottom of the buried tube (—it wasn’t—), I saw that an old drain channel I had created to entice flow out of the small paddock was flowing like a raging river. Yay! A success!
But when I reached the fence line, where the ditch opened to my main drainage swale (I thought), I found that the water was curling and flowing back into the paddock, traveling along the inside of the fence down to the bottom corner by the round pen —just the area I was trying to avoid.
It was now raining hard again at that point, and I was about as wet as could be. I was tired, saddened, and feeling entirely defeated. Dragging my sorry soaked self up toward the house, I checked the rain gauge again to see that an additional inch had fallen while I was out.
I think we’re gonna need a bigger boat.
