I'm studying a Rescue Horse farm. I'm working on some ideas to help

with water drainage as first priority.

So far I've seen the main barn needing gutters and a water catch

system that can be used for watering horses in dry times.  I've also

noted ripping the soil on the hillside at a slight angle could help water

flow on past the arena that gets flooded. Regrading the road with the

idea to drain off water and channel down sides instead of erroding 

the road would be another helpful plan to implement.

Other thoughts would be to plant foraging trees outside of fencing, that

can be cut and fed to horses to supplement feed. Also decrease some

paddocks & plant in nitrogen fixing cover crops(non-toxic to horses) to let

the extended area, that has been trampled and bare, recover.

I'm not sure how or when this project will go at this point, but I'm

excited about the possibilites!
