Douglas County rural manure piles can become a water issue
A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.
A manure pile on rural acreage looks like a smell problem and nothing more. It is really a water problem waiting for the next storm. On Douglas County land, over-intensive grazing and poorly managed manure are among the main drivers of noxious weed infestations, and weeds are only the part you can see.
The water part is easy to miss. Stormwater out here does not run to a treatment plant first. It flows straight to the nearest creeks and rivers, carrying whatever it picks up along the way. A pile sitting near a swale, a driveway flow line, a drainage ditch, or a channel that only runs after rain is feeding that runoff directly.
So three things on the property are really one thing: where the animals gather, where the manure is stored, and where the water goes when it leaves. Place a pile in the path of any of those, and a storm turns a private chore into something that travels downhill onto a neighbor’s land or into shared water.
Before you bring in horses, goats, cattle, or other livestock, it helps to walk the ground during or just after a hard rain and watch where the water actually moves. Keeping manure handling, pasture rotation, weed control, and drainage in the same plan is what keeps an acreage from sending its troubles to everyone downstream.
