draining a 1 acre pond

[brickled]

i have a 1 acre pond, around 10-12 ft deep at its deepest point. i want to
drop a 5/8" garden hose into it, start a siphon (got plenty of downhill to
work with) and drain this pond down to around 5 ft. has anyone out there
attempted such a feat and if so, how did it go? if a single hose won't do
it, i'm thinking of adding a 2nd and then a 3rd, etc until i get adequate
volume going out. obviously, i'd like to do it w/ less hoses if possible.

A 2" or 2.5" dia. PVC siphon will work, and very inexpensive. Bring
the pipe outlet several feet below the pond level to get a fast flow.
The warmer the water the faster the flow.

A garden hose and cap to get the siphon going will help.

Just curious. Why do you want to drain such a large pond? As for actually
doing it, if you don't mind waiting half the week for it to drain, you could try
what you suggested, or you could just rent a trash pump and be done with it
today.

i have many areas along the shore of my pond that are not quite deep enough
(massive weed growth around shallow points), once i get (and keep) the water
level down some, it'll dry up enuf that i can fix those high points.

u're right, i could rent a pump but i worry about putting so much water onto
neighboring properties all at once. i figured that if i could get drained a
little on the slow side that i would avoid an angry phone call or two.

Or a shop vac, if you can make a good connection.

What's the time period? I've used 1/2" tubing to drain down my lily pond of
1,000 just a few inches and it took hours, I don't think a garden hose
would make much of a dent, that a good rain couldn't refill. ~ jan

I think that you are going to need a bigger hose. And I would definitely let
the neighbors know that some water is coming their way.

Hi,
First you may need a permit to do this. Second to drop this five feet you
are talking approximately 1 1/2 million gallons. Set up a hose, start the
siphon and time it filling a 5 gallon bucket. Then do the math. If you can
get 25 gallons per minute you're looking at over 45 days IF the hose does
not get blocked or as someone else said it does not rain. Another thing to
consider is how is this pond's level currently maintained, I.E. spring,
stream, runoff as this will have to be factored in.
HTH -_- how
no NEWS is good

Simple two step process:
1. Call the local volunteer fire company and join if you have not already.
2. Ask if they would like some practice draining a pond. You may have to
pony up a few bucks for gas. They can pump out to your stream or fill the
tanker.

You may have to improvise some sort of fish strainer. The easy way is to
sink a tub at the level you want to reach and pump from there.
Your pond may be in a handy location for them to use as a water source when
the tanker runs dry and they need to run for water. In that case you can set
up a permanent system to supply them. A typical fire might involve three or
four runs, so you are not risking much water out of your million gallons.
Be community minded - this may solve the permit problem.
