runoff ditch ..what to do?

[Moon]

I have an area I've slowly been clearing. It has been overgrown for years, and has a 3ft ditch to show for it. Water run off has created this ditch, and I'd like to make the area easier to bush hog.
The ditch is to wide to drive across or stradle. If I fill it in, the water has to go somewhere, so I have to make allowances for that. So, without a BH what would be the best way to tackle a ditch like this? It is on a 10 - 12 degree slope and about 30 ft long.
Any ideas?

Thanks,

Moon,

Like you said, the water will keep coming. How much volume?

Can you post a pic so we have a better idea?

Sight unseen, I would probably suggest putting in a 12" or larger culvert and covering with dirt.

A couple things might help.

Widen the ditch so the water isn't cutting when the volume is high, but flows over a wide area.

Putting some low barriers in it to slow the water down and trap sediment, which in time will fill up the ditch. Rock wraped in chicken wire works good for this.

Redirecting the source of the water. Is the ditch beginning at a hill or high runoff location? Cut another shallow ditch, or build up a diversion hill to redirect the water to an area that can handle the water flow.

Get some grass down to stop the erosion.

Put some gravel in it, some drain tile, then more gravel.
Cover with some topsoil and let Mother Nature do the rest.

The real question is where is the water coming from and is it still flowing with enough force to continue the erosion. Is it possible the erosion occured when the slope was bare and now that there is vegetation on the slope, is the flow reduced.

You're probably going to have to go out during a good "toad choker" to see exactly where the problem (if it still exits) originates. Once you know what the problem is, there numerous ways to control it.

I like drain tile but I found out the hard way that the 4" perforated clogs with leaves or other debris pretty quickly which is why I recommended the 12" or bigger.

Opps ....i intended to mention that the volume of water is low. I've never seen water running through it, or standing in it, other than mud at the bottom ...but I have not looked at it durning a heavy rainstorm.
I planned to put gravel in it, but it would take quite a few tons. So then I thought I'd push and box blade some earth back in the ditch, burying some drain pipe, but there is no obvious collection point where I know the pipe will get all the water (I put in a drain pipe at another location and the water misses the mouth of the pipe ...so I want to avoid doing that again).
The water is coming from two seperate hillsides. It has been a natural run off spot for quite awhile. It leads down to our pond.

Thanks,

As mentioned before a couple of 20' lengths 12 or 15" poli, doublewalled culvert should work. About $100 for 12", $125 for 15". One man can handle it, can cut in half with circular saw for easy hauling, and snap and or duct tape back together. Cover it and drive a truck over it. Similar situation here.

What are your plans for this particular area. Are you clearing it to use it for pasture, crops, etc.? Is the ditch continuing to erode, or is it fairly stable. It might be that you just need to leave it as is, and just make sure it stays "haired over." If the sides of the ditch are steep, you could just push a little dirt down from each side to make sort of a waterway (as opposed to a ditch). If something like this has native grass and other vegetation growing in and around it, it is usually fairly stable; that is, it is not continuing to erode. These are wonderful places for all types of small game and song birds.

I'm not ragging on you, you know what your situation is, but loss of this type of habitat is the very reason we have all but lost huntable populations of Bobwhite Quail, rabbits, and other small game here in GA.

When I get on a tractor with a Bushhog or a plow behind it, I sometimes just have to make myself stay out of areas like this. I guess the human eye just wants it to be clean!

No special or planned use for the area. It's just a hillside that I bush hog which is between the pond and State Route (busy road). It had been overgrown until last year. I about tipped the tractor in it when I first found it. I don't want a tractor accident ....otherwise I'd just like to be able to traverse the area. I have other areas we do let grow up just for wildlife. The errosion from last year to this year appears to be negligible. I'd guess the damage was done over a very long period of time.

off topic but...nice Mastiff. I have one thats 16 weeks old.

As others have mentioned go with the 12" or 15" culvert pipe. I have a similar ditch although mine is about 300 feet long. It only has water in it during winter and spring. This year it had very little in it, but in years past it has been 10 to 12" deep in places. I put pipe in select locations to cross and reduced the slope on the sides for easier mowing. I wouldn't do anything to impede the flow of the water as it could have very bad results.

 

[Highbeam]

Provided that the entire hillside has a general slope parallel to this "ditch" I would just level it out. Further, if there is a pile of deposited sediment at the end of the ditch I would go scoop it up and put it back where it came from. It sounds like the hillside just ravelled out because the surface coulcn't handle the water running across it. Refill the ditch and get something growing on the surface so it doesn't happen again. I would try to provide a sheet flow situation for the runodff rather than a canyon.

Reclaim your land. Repair the damage.

We have lots of fill and grade projects at work where a side slope will erode and make a canyon type structure on the slope. This is preventable by stabilizing the soil surface.

I had quite a huge gully that was caused by runoff from my neighbor's parking area just uphill. I filled it in with #5 gravel. It has stayed put. At one point there was a hole at the top of the gully that took about 4 of my Gravely cart loads to fill it. (This was before I had the JD)

If you have a huge amount of water and there's an outlet for it a little downhill, you could put in a drain basin and some perforated pipe and then fill with the (at least) #5 gravel over it all (leaving drain basin free).

Thanks Euby! Actually she's a Great Dane ...but they do look alot alike. Another member on here has a Japenese Mastiff.
....and welcome to TBN. Great site.

Highbeam, hardly any sediment at the bottom. I have a trail that goes between this ditch and the pond. We dozed this area a few years back. That probably took care of the sediment build up and there has not been much to speak of since then.

Kubota Steve, I'm thinking I would need some gravel under the pipe. But this might be the best way to go.

RalphVA - That was my first thought; to fill it with gravel. After closer inspection I think it would be the most expensive way to take care of the problem. I'm thinking some gravel and a 12" culvert, and then cover it all with a bit of dirt and get some greenery growing.


Thanks all!

I've dealt with several similar situations by using the BH to clean up the ditch and then filling the ditch with 1's & 2's. I don't use a culvert pipe unless there is a road going over top. Pipes tend to clog up and cause other problems. The large gravel allows the water to filter through, holds the soil, and never clogs. This is what you see along the highway where there is a drainage ditch running down a hill.

My 2 cents worth. /forums/images/graemlins/smile.gif

Another idea.

Build a rock dam uphill from it or possibly in it. Put maybe a foot of sand in the bottom of it, then dirt. Then put in plants that'll tolerate both wet and dry, like Joe Pye Weed and trees that like wet like River Birch. This is a rain garden, designed to capture rain water runoff before it goes downstream and creates problems.

I did this upstream of much of the gully that I filled. Have the dam and have filled behind it. Haven't gotten around to putting in plants yet, mainly cuz the sawdust I used mostly for fill isn't decomposed enough for plants yet. Getting close. It hasn't washed away.
