Group Effort
Under a strange sky on a day when rain wasn’t predicted, Cyndie and I planned to work on improving the landscape around the round pen to stop the sand from getting carried away in runoff every time it storms.
The passing disturbance in the sky overhead dropped some intermittent showers that were light enough that nothing became soaking wet, so it didn’t interfere with our efforts.
While Cyndie worked on the low side of the round pen, reclaiming sand that had spilled out when 7 inches of rain poured down on us last Wednesday, I prepared the soil on the outside perimeter by pulling our ABI rake/grader behind the Grizzly ATV.
It was working perfectly until impact with a rock sheared the bolts holding the hitch on the Griz. With towing done for the time being, I picked up a shovel and went to work shaping a trench and berm combination in hopes of preventing the water from flowing directly through the round pen.
If I got the slope shaped right, the water should meander around to the low side where it can make its way harmlessly into the drainage swale, minus our precious sand.
Obviously, this is effort that would have best been done before we brought in the sand, but we were in a hurry to get the footing in the round pen improved in time for the training sessions that had been planned.
With Delilah off-leash and the horses free to mingle, we had a lot of “helpers” that were keeping us company while we worked. Between her bouts of barking at the horses for no good reason and wrestling with their exercise balls that she thinks are her toys, Delilah took time to stop by and help me while I dug up the sod. I would toss a shovel-full to the perfect spot for building up the berm, and then she would grab that piece of sod like it was a piece of steak, carry it away, and tear it apart heroically before coming back for more.
Seriously, she took three of the best pieces I had placed in a short span of time, but I didn’t have the heart to dissuade her, as she seemed to think she was doing the greatest job of helping me. That berm better not leak at that spot or she is going to be held permanently responsible.
The horses were also inspired to participate in their own way. Shortly after I got started, Hunter grazed his way so close to me that I didn’t have room to work the shovel. At that point, he was standing on the area I hadn’t dug up yet, so he was packing down the soil I had just churned up with the grader. At that proximity, he also ended up sharing the cloud of flies that were all over him.
They have my full sympathy about the flies. They went up my nose more than once which can really make one irritable. I considered trying on one of their fly masks, but figured the fit might not work out quite right.

Legacy and Dezirea wandered over to inspect my progress and test out the trench. It confirmed for me that they would have no problem navigating the altered footing in the vicinity of the pen. I think it met with their approval.

Uh Oh
I’ve got a problem with my little drainage swale that we paid to have excavated last fall. It is already filled up with sediment.

Part of me wanted the swale to be a bit deeper than it ended up, but we had to go with the existing geography of the surrounding land, and to achieve the gentle slope we want, over the full distance we need to cross, it can only be cut so deep.
One source of my problem is that the excavation happened so late in the year that I wasn’t able to get good coverage of grass growing over the full distance to hold the soil in place. The other source of my problem is one I overlooked. There is a lot of runoff coming from the paddocks. I’m not sure what I am going to do about that.
It frustrates me to think that I need to re-dig the swale already, and destroy the areas of grass planted last year that did take, but right now, that seems like the thing to do. Get it dug out now and allow myself plenty of time to get grass growing along the full length.
Solving the runoff from the paddocks is the bigger challenge. I could probably install the little plastic fence that is commonly seen at construction sites, but that is an ugly-looking solution. I want the water to drain, but I don’t want it to carry any topsoil away when it does.
I’m going to need to do some research on that one. Just like so many things in nature, it’s a complex situation with multiple influences and the full range of possible outcomes. Maybe a little pond at the low spot of the paddock to act as a catch basin that can then overflow excess water into the swale, without the sediment.
Then I would just need to dig out the pond occasionally, and I could move the soil back uphill where it came from. I’ll take some time to pond-er the possibilities of that potential solution.

Wet Again
I have another picture for you to compare. On Sunday I posted a picture of the standing water in our paddock, and then yesterday, I posted the improvement visible after a couple of days without rain. Today, you can compare the difference a day —and 2-inches of rain— can make. We are wet, all over again.
Unfortunately, we experienced two different failures that contributed to the amount of water that inundated that large paddock. First, I wasn’t able to reconnect the hose that Legacy pulled off the trough and dragged into the paddock because he had squeezed the threaded end out-of-round. In haste, I grabbed the closest hose at hand, but it was a poor choice. It was one of those new collapsible type hoses, and for this application of draining the tank by gravity, that hose presented too much resistance. On top of that, it wasn’t long enough, so I grabbed another old hose that I figured I wouldn’t miss if it ended up a permanent fixture down there, but the reason I wouldn’t miss it is because it kinks easily. Kink, it did.
The end result was that the water trough beneath the downspout overflowed and poured directly into the paddock.
The second failure was a plug of silt and debris that dammed up my little drainage channel that runs behind the barn. It occurred right at the worst spot for the water to pour out of the channel and run into the most problematic spot of that paddock.
What that means is, all the water from that 2-inches of rain that fell on the barn roof, front and back, ended up pouring right into the paddock. This is the very thing that I established was the first and most important issue we needed to tend to in order to improve the state of our paddocks. We devised some rudimentary systems to prove the concept, and they have been working surprisingly well, up to this point.
I hate to be moping about this, especially in face of news about the level of suffering the people of the Balkans are enduring due to unprecedented flooding there. Our situation is frustrating, but it’s nothing like that. Yet.

Directing Flow
While walking through the muddy driveway in front of the barn I noticed that one of the “fixes” I tried last fall to control runoff appeared to still be doing the job this spring. Previously, the water on the barn-side of the hay shed would flow straight across the drive path into the paddock. I made a little channel at a diagonal across the driveway in hopes of directing the flow toward the far side of the paddock.
With all the snow piled up beside the driveway, there was nowhere for the water to go, so it began to pool up. I grabbed a shovel and set about remedying that situation. While I was working on it, Delilah showed up to help. She had already been racing through the mud that is beginning to appear in several places, so I guess I should be happy she likes playing in the puddles, too.
When it was time to head in, Delilah was a mess. Aaaah, spring. She has already started digging up the dirt that is becoming exposed at the front two corners of the hay shed. She appeared to be trying to get as dirty, muddy, and wet as was possible in the short time she had to run free after I got home and let her out of her daytime kennel.
