After hard rains a couple of weeks ago noticed pond was more turbid than normal - downright muddy in fact. Checked out entry to sediment pond and found water has cascaded into deeper area and eroded about a six foot hole.
First thought was to fill and repair with limestone rip/rap but that stuff is expensive.
Used 112 60 lb sacks of Home Depot Quickrete - Look like it is doing it’s job after last couple of day of rain. Anyone use this stuff? George

Wow, that's a lot of premix. Just over 2 cubic yards of concrete! That should help put the brakes on the erosion.

George, Had the start of the same problem on my inflow. I also used 80lb bags and it has worked out great. The only problem I have is the paper is starting to disintegrate and floating in the pond. I have been sending the kids around to pick it up every evening. Looked at getting limestone instead but the cost was higher and getting the tractor down there to spread it would have made my problems worse. Quikrete actually makes a riprap bag of concrete where the paper is biodegradable but I could not find a source. Very nicely done and I think you will be quite pleased with the results.

Hi Ben, thanks for your response. I have seen retaining walls built out of this stuff so thought I would give it a try - glad to hear of your sucesss in handling an erosion problem. I don't mind paper floating around the pond - just may act as "cover"..
Thanks again, George

Jodi and I asked Mike Otto about best way to build a retaining wall. He suggested quikrete bags should work if you hammer rebar through the bags thereby connecting them once they harden up. haven't don't it yet but will when time permits. I "hope" I can find the 40 lb bags unless I can get George's son to help! heehee.
That is interesting George that the quickcrete was competitive in price with the cost of rip rap. Of course I suppose that would depend on the distance the limestone would need to be hauled. We are fortunate in our area to have quarry's fairly close.
Looks like a good solution. Thanks for the pictures. Will keep it in mind if I am ever faced with that problem.
Bill, no. "Rip Rap" can be almost anything that is heavy and solid to prevent erosion...even cars. Limestone is often used because it is the most common substrate there is. It is normally cheap, readily available, lasts for decades, and adds some minor benefits benefits in water chemistry and pH buffering. Limestone needs to be pulverized smaller than a 60 mesh to be "fast" acting in pH buffering/change.
Oklahoma River Rock is only nearby rock and not good for rip-rap. Limestone is some three times higher than sackrete due to long transpoart costs. We are fortunate that we have good sand and clay soils in our area - glad no rock or leaky ponds. George

I was also flabbergasted to learn that in parts of the country, sakrete is cheaper than limestone. I suppose I'm fortunate to live where I do, and have cheap, plentiful limestone readily available. And no leaky ponds here either!
Shoot, flooded limestone quarries make up a great deal of the local landscape. Always intrigued me how they remain full of water.

Here it is not so much the cost of the limestone but the cost of delivery that is astronomical. Several quarries close but most of the time delivery more than doubles the price unless you start maxing out (20 ton) the truck. Wish I had a good way to transport 2-4 tons.
Haul bills do add up. We recently had 60 tons of #5 stone hauled in and spread, and the total bill, including delivery, was less than $600.
Small quantities do increase the costs significantly. That's why when I order stone, I never get less than a tri-axle load. Dump it in a pile someplace, it won't go bad and I'll end up using it for something, somewhere down the road. Actually pretty handy to have around.
Especially driveway stone, and rip-rap.

No kidding Tony. Of course, my pond sits in the county where all the limestone for the Empire State Building originated. They'll let you come pick up scraps. I half figured it would be limestone under the soil in my ravine, but it was soapstone.
Yep, the building right below my shop was once a limestone fabrication business, and when they left they simply abandoned cut slabs and shapes of limestone of every size and description. The entire neighborhood helped themselves to whatever they wanted. I think there's still some laying on pallets down there.
Common as dirt, here.

We always keep two or three piles of the stuff around the farm so we can get a tractor loader bucket full to fill a pot hole in the driveway or whatever. I try to keep a pile of lateral rock (2-4") and AB3 (1.5" and lower with fines) for general use around the farm. Right now also have a couple of other piles of graded size specific to concrete use so I can mix up small batches of concrete in my tractor 3pt concrete mixer. My small mixer is my answer to "sackcrete" when I need more than a bag or two of it at a time.
In May, weather permitting, I will be expanding the pond and doing some erosion control work. My water PH is 7.9 to 8.2 and 170 ppm alkalinity. Any problem with using limestone rip rap in my swales feeding the pond and as a border around the pond?
Any concerns on PH and alkalinity numbers?
Thanks,
Bill

I see they lifted the weight limits on the roads already so time to try to get things going on the renovation and erosion control measures. I will order up some limestone rip-rap.
