Not sure what you mean that it is 4' above your water. What about the area under that? Is the netting hanging down the sides? And how is it staying 4' above, on some kind of frame? Those hungry herons are just waiting for their chance to get another one of my koi.
The net is stuff they use for fishing, i.e. ocean, lakes, etc. 5 inch weave. I wove a rope through the edge, per what the company suggested, with the rope you can pull the net tight. I have 4 fence posts one on each corner of the pond, with some fiberglass rods in the bog. The fence posts let me pull it tight, the fiberglass rods in the bog let me drape some of it over the rods to keep the heron from attacking from the bog.
The net is from 3-4 feet over the water with the edges draping down to the ground, sort of. Some places it touches the ground other places it does not.
The main place the heron has attacked, hours of video watching the sucker, is the walk out area, the bog, one place on the upslope of the pond. The heron likes to stalk up to the pond, curl its neck and strike, the net does not allow the heron to do a full strike and reach the fish or water. I have never seen the heron put its head down to push up netting etc to strike. It has flown over the fencing (previous chicken wire) land in the pond, floating and try to get a fish, it failed.
Once the heron comes to visit it comes every day, never stopping. I have filmed it giving up and eating crickets out of the garden..........it is welcome to all that it can eat. Here you just never know when it will decide it is time to stop by. One year January, one year july, this year, not yet.
This is a view from the deep end, it is a little lower here, the upslope is 4 feet higher than the pond, to keep the heron from walking down the slope and reaching the pond i have it a little lower. The walk out area I have it high enough to walk under it into the pond. I have it on clips, easy to remove if I want. When it snows it is drug down into the water, I have it removed during the winter. I float a piece of liner in the 5 foot area, the fish hang out there barely moving when it is cold, heron safe.
This is the netting without the black uv coating, also the black makes it less visible
