Posted By: Scott Williams Pond deepening.... - 09/09/13 02:09 AM
Hello. I am new to the forum and am looking for some advise. Just bought property with a 1acre plus pond here in northeast Pennsylvania (specifically luzerne county) The pond appears to be man made some time ago (50+years) and has a healthy population of bluegills, sunnys, catfish as well as largemouth bass. Also turtles and an infestation of frogs smile .

I have measured the depth and the deepest part is about 5 1/2 feet. I would like to deepen it significantly to help support the bass population -I am thinking to somewhere between 12-15 feet. The pond is adjacent to what I would classify a seasonal wetlands as well as a few swamps. I have been doing some research on siphoning and like this a method of lowering the water level.

What are the likely governmental challenges ?

Is the sediment that we are removing useful in some way? Is it something that is fertile and can be used as a topsoil ?

Is there a chance that significant deepening could cause a leak? I have also been told that one leak solution is a a bentonite lining. Any problem with this ?

What is the best time of year for this type of project ?

If we drop he pond significantly below the water level of the swamp, is there a chance the swamp will dry out and return to open water rather than sediment and muck when the water level is returned to the pond?

Sorry if these questions are repetitive, this is all new to me.

Thanks

What are the likely governmental challenges ? Definitely check into what is possible before you get your hopes up.

Is the sediment that we are removing useful in some way? Is it something that is fertile and can be used as a topsoil ? Yes, good after it breaks down. That is if its organic sediment. If its something like sand, then its just a fill material.

Is there a chance that significant deepening could cause a leak? I have also been told that one leak solution is a a bentonite lining. Any problem with this ? Yes, could leak. If you go as far as your thinking with this, the best is to have it compacted properly. Don't rely on bentonite.

What is the best time of year for this type of project ? Shortest answer, when it's the driest smile Good luck if you can predict the weather eek

If we drop he pond significantly below the water level of the swamp, is there a chance the swamp will dry out and return to open water rather than sediment and muck when the water level is returned to the pond? Most likely the plants will return in full force. The muck that is left will slide down into the deeper areas if they are given a chance.

I hope someone else will chime in with the best place for you to get government help.

Feel free to ask for more questions or more detailed responses.

......by the way, welcome to PONDBOSS.

I'm in upstate NY, did some research into what it takes to "legally" renovate or alter my 3/4 acre private pond. I have areas of low or wetlands by plant or soil type not so much in a DEC zone so I figured I better check into it in case a neighbor complained. US army corps is who you go to first. I was told by them - the US army COE basically if any water has the ability to make it to a US water way and or there is any amount or any kind of ferns, cat tails, red maples, damp or wet or soggy soil or any type of wetland plants anytime of the year you have to apply for a permit. If you are in the middle of no where it might be worth taking a gamble I guess. They told me I can apply for a "joint application" basically a statement saying I have permition do do what I want but it's not an easy process and your better off hiring a consultant.

As far as sludge, got plent of it. Been sucking out with a 2 inch trash pump hoping to get good garden soil out of it.

Good luck
