We were concerned about predators in our area, mainly Herons. We had been cleaned out several times before. To accomplish this I constructed this quick screen using 1" pvc conduit and 90 degree elbows. It floats if you wish or you can elevate one end and float the other. It cost less than $20 for all the pvc fittings and cement. The screen was separate. Zip ties attach the screen.

Supplies: 1" PVC Conduit 10' lengths (variable number depending upon size). 4 each 90 degree elbows. At least one coupling. Fast dry cement. 8" zip ties. Larger or smaller pipe may be used depending upon pond size. All parts are one stop at Home Depot, Lowes, or other hardware store.

That's nice and thanks for sharing. But I've read that herons will peck through wire or mesh -- not that they will succeed in getting the fish, but could still cause injury. Keep us posted on how effective it is!

Any suggestions on how to strengthen it would be helpful. Someone said they rigged some random strings as a distraction.

Thanx @Modela you've just solved a problem weve been having with our new net I'm going to copy this idea if you dont mind that is

It looks a very interesting project so simple to do as well , what was your initial outlay on this project please ?

I'm going to copy this idea if you dont mind that is as it will tie in with what weve been doing but without the bungee straps :happy:
As to random strings herons do not like stepping over fishing line tied between posts close to the pond but far away enough to stop them spearing fish [I believe about knee height] Note* I suggest fishing line because its harder for them to see and thus to try and step over , try strenthing it with bungee staps tied corner to corner , in our pond we have the net kept clear of the water by a bungee strap tied across the pond with the net laid across it it should work or add a section of pipe and fittings cross wise across the middle of the net

I used hardly any of the PVC glue and few of the 8" ties which I like to keep around. The bell ends on the elbows and pipe eliminate a lot of the need for couplings. It turns out we could have done it with two pieces of pipe. Don't forget the need for an extra coupling or two (you will see why) at $.55 each. You can use larger or smaller conduit depending on how large you make it. Feel free to use and/or modify.

After 20 Years the pond is still hanging in. The art is steel, copper, and brass. We finally started having success with our filter after we followed some advice to double the size of filter for a rated filter system (Pondmaster). Fence in front is too keep one fish (Evel K) from jumping out.

@Modela BTW, your waterfall wall looks very interesting! Could you post a few more pictures of your pond in general, and the wall in particular?

I just love that wall and backsplash [or whatever it's called]? Was the backsplash custom made? Your motto should be "May all your herons be etched in the mind, and not in reality!"

Use lots of 45's or 22's. Somewhere once I looked up an online "calculator" for using angles to make a circle shape of a certain size, and it gave the dimensions for each straight piece, etc. I'm math-challenged, so I have to use AIDS.

Same here Maggie Math and I do not see eye to eye never has been and never will be [much to the disgust of my father who was head of rates in the local council ].

The back splash was built when the house was built by Ken Scott Designs. It was coordinated with the brick work. The pond was a last minute thing and we were glad we added it.

The elbows are also available in 45 degree angles so you could make an octagon.

Another option is to heat-bend PVC pipe into a circle. Any propane-driven torch, such as we use here to burn weeds, will easily heat small-diameter pipe for bending. The only problem that I'e found with doing it is scorching the pipe. If I were to do a round one, I'd make a form and bend around that a little at a time: anchor one end, heat a 3' section, bend into place, heat the next 3' section, etc. I've done it with 2" PVC pipe successfully.

I have a 6000 gal. pond with Heron visitors the first year. Hung two rows of fishing line with CDs hanging from them every 10 feet. No Herons for the last five years.
They are very reflective, very bright in the sun.Recently saw a Heren look over our fence but immediately flew away. Hope this will help those with Heron problems.
