Hi guys... great forum! We purchased a property with a 2 acre pond. It appears to have been put together well in the early 80's and seems to be in good shape. It's has a steady amount of water coming in from neighboring farms and a nice steady outflow out of the 18" horizontal overflow outlet. I have no interest in screening the outlet with the disaster stories I've heard from plugged screens... but is there any reason why I can't simply put an elbow on it to raise the level a couple feet and also help prevent fish from going through the existing horizontal drain so easily?? So the next question is where I can find an 18" elbow or maybe even a T Connect to fit? It's simply a typical 18" culvert... or any other ideas to make this work as well?? thank you!!

The overflow pipe is a typical black plastic 18" culvert with a smooth inside... does anyone know where I could find an elbow that would slide inside (of any type of material)? I don't plan to make it permanent at this point... this was I could control water level if I decide to at some point.

I think they make PVC elbows in that size.

Thank you!! I was just looking at that site. Maybe I'll end up just building a box around the existing pipe that can be staked down and removed... it doesn't have to be water tight. I have a decent flow as mentioned above so the water will come up.

There are water control structures that attach to the overflow pipe and control water height by adding or removing boards. I don't have a link right off hand but google "water level control" or something similar.
If it is just very temporary, you could just put a peice of plywood and cover about half the opening. T posts or something in front to hold in place till water pressure got against it.
Be aware of any large rain events coming so you could remove it if needed.

They ain't cheap. We have 2 inline ones on wetlands, and 2 inlet ones on ponds. https://www.agridrain.com/shop/c85/water...rol-structures/I brought my ponds up 5-7" per year to allow plants to adapt.

Good stuff! Thank you!! I don't want to close the outlet off or down in size at all in fear of the big rains. Instead I simply want to change to a vertical outlet in place of the current horizontal in hopes of keeping a few more fish from escaping... then to also bring that water level up another 1'-3' possibly. At least for now, I want it as temporary as possible in case I decide it's best to revert back to the existing.

I am not sure the planned modification will change the fish loss much. The trick there is a lot of surface area on the screen. I use hog panels with 1/2" mesh fastened to the outside using hog rings. My panels form a "U" around the drain with the side runs cut to taper up the banks on either side of the drain pipe such that the top of all the panels are level. The smaller mesh can be cut shorter that the height of the hog panels so high water will flow over it if a gully washer happens. Not sure if I described this well enough to understand.

Understood completely... thanks Rah. My main focus is to get the water level up more than the fish loss. Thanks again!

I got mine from a commercial plumbing supply company.

They talk about custom models on their web page. Maybe they could make you one like that with a removable end panel so when you wanted the water back down just slide the end out and leave it in place for the next time you want to raise the water level.

....

Maybe install a T instead of an elbow so you can just cap it when you want the water level higher?

You're welcome. Bear in mind there will be a lot of upwards force on the joint due to it displacing a lot of water - ie acting like a boat. You may need to encase it in concrete.

The water control structures are often held down with spiral ground anchors and a strap over the top.

The good info just keeps coming in! Thanks all!! Planning to do the t-pipe now and plug the horizontal end. This will allow us to have a choice of a couple levels. After a year or two of ownership I can decided on more of a permanent setup. Side not... I have a fish list now... I decided to hit it hard up front which will hopefully pay off down the road. I plan to do a little more homework on the pond before we dump them in but the plan is to get some fish back in this pond in the next week or two! Pond is right at 2 acres 200 LMB 1000 BG 1000 HBG 400 Shellcrackers 200 Catfish 20 Grass carp
