It all started because our kids wanted a swimming pool...so last summer after hearing the same thing over and over I finally told the kids to go "dig the hole and you can have a pool"....the kids spent a week out in 105 degree heat with shovels. Well we always wanted a pond on the property...so the adventure started.
Keep in mind that we figured all we needed to do was dig a hole and fill it with water. We didn't even bother to check online for information..after all hubby "knew what to do"
We got a dirt guy out to "dig the hole" and build the dam. After a few weeks we liked the what we saw. Ended up being about 3/4 acre in size and 22' deep in the center. We have very rocky soil, so we brought in what we thought would be enough clay..boy were we wrong.
Figured we would use the well (right next to the pond) to fill it..low and behold that well only puts out about 3 gallons a min. I know, I know we should have tested the well
this started. Well on lower part of property puts out over 40 gals per min but has no power..so off we go to buy a generator to run the well pump we had installed over 500 feet away. Next I lay the pipe to carry the water to pond. Well guy said I didn't need to "glue" the pipe since it would not have much pressure...boy was he wrong. One by one each pipe blew apart, so one by one I glued each piece back.
So far so good..right...
Pond gets a little over 1/2 filled...and then never rises. We stop filling and as it goes down I see a massive boulders that ended up being the size of a cars (at the bottom) with a splits down the center. My guess is the rocks fractured from the drilling "tooth" used to "chip" out parts of the rock.
So with winter approaching we decide to wait until spring to deal with it. Kids went fishing and brought home some bluegill and bass and put them in the pond never giving them a second thought. Spring comes but late rains fill pond so we wait until only about 3' of water then rent a pump. While pumping the water I see spawing beds and notice blue gill fry, and a few fat and happy bass.. so now I have to put the fish somewhere. As I'm doing this we have a crew grading an area for a barn on the property. The area where the barn is going always seemed to be green, I now know why..a natural spring. So I tell the guys barn is going in a different spot, and to dig out the spring area..once again the process starts..now I have a natural spring fed pond about 20 x 30 and around 4 feet deep..perfect to put the blue gill and bass while we work on the "big pond".
Here's where we can use some expert advise.
We have had all the bolders taken out and removed any rock bigger than about 3" x 3"...no small task. All told it's been a fun adventure, but be careful what you tell you kids
it may come back to bite you.
put down 4" of #9 screened clay over the entire area (bottom/sides), then laid epdm liner on any areas we thought we might have trouble. Put down another 4" of clay over this( 8" total). Do you think this will be enough clay?
Added a windmill for aeration and will be adding structure for the fish before filling. We also put in a spawning area for the fish.
Have two spillways, but would like to install a pump "just in case", we need to drain down the pond, any ideas on types and sizes of pumps? House is located about 125 feet from pond (uphill), so we will be using electric to power any pump. Would also like to be able to use pond for wildfires if needed.
Any other areas you think we need to address,BEFORE we start filling again?
hubby doesn't think so
ps...the moved fish are doing just great
