Digging out a pond
I recently had a large springfed pond cleaned out and deepened form 12' to 30'.
The pond was 570'x 900' the contractor that did it brought in a cat and pushed a dirt berm out so that his excavator could reach where he needed.
it only took 6 berms to complete the job but it took almost a year for the water to clear again.
But if you have it done this way don't forget to bring a large checkbook

Unfortunately, I dont really have much dirt to push out to build a pad. How well with an excavator dig through ice? If I was to do it this winter after everything froze up. I could clear out a road and a working pad so that the ground freezes really good. I am just not sure how well it could break through the ice.
Ahhh, I see on page 3 where this was already recommended...  I think Ill give it a shot.

Very curious about the trash pump idea for removing silt and mud from a tidal ditch where I want water for the boat on every tide. Would this idea work for this application?

We use this method to keep our boat wells clear in Norhtern Michigan. Mostly sandy silt and silt. The looser the settlement, and the fewer organics that are mixed in, the better the results. We can clear a foot of muck from a 24'x 12' boatwell in an afternoon, no problem.

JD, the one thing you will have to be aware of though is if it is the tide itself bringing in the silt, you will be fighting a losing battle.
Natural erosion or siltation is a powerful force, the Army Corp. of Engineers spends a whole lot of time and effort on combating this very thing every year.
The best way to clear it, and keep it clear, is to make sure that the tidal flow sweeps the ditch clean every time.
Best of luck.

The area fills in with land slope runoff. My neighbor is going to bulkhear his property, (I have a seawall). I'm ging to try this when his work is completed. Also thinking about a piece of pvc with holes drills in it to wash out the area on outgoing tides only. Would take longer, but work?
Thanks for help.

If the area is filling with sediment from run-off you will find it is much easier to deal with the sediment BEFORE it gets to the water.
You need to develop some form of trap for the sediment. The usual method is to make some form of depression or pond-like structure near the ditch, this way the sediment can settle in the depression before the water drains into the outlet.
They sell a cloth product generically called geo-textile fabric which will allow water to pass through but not sediment.
The simplest way may be to have the water settle into a depression and bury some drainage tile underneath, this will allow the water to seep awy but the soil will stay behind.
Best of luck.

Beagle, did you build the retaining wall around your pond ?
