    when you cook up your first walleye, you will remember the event
     
  2. In Texas these are what we have for lake perches so you can understand my confusion.

  4. More fountain/pond analysis

    Okay the first two pics are the auto fill pit. You can see how much it dropped overnight from the pic when it is full.

    Where I think my problem or one of my problems is.
    The water on this waterfall is going back behind and running down the stone under the lining. I piled to stones some to deflect it but not 100%

    various other pics just cuz I took them

    Is there a way to get all or most of the water to just go off the stone and down rather than some rolling under the stone to the back?

    Why not make a pipe extension with holes to direct the water where you want it?

    Like a windowsill it might need a saw cut on the bottom edge to break the tension.
     
  7. Makes sense. I wonder how I'd go about doing that at this point.:confused:

    WOW!!:dizzy::dizzy:

    Either this is one very old installation or it belongs on a 'Hacks and Pikers' page. Waterfalls haven't been built that way in years and years.
    From what you have stated, this is definitely the location of your leak. Over time the ground has experienced settling due to the weight of the rock/concrete resulting in the liner at the rear of the waterfall spillway is lower than the height of the spillway weir. Unless you shoot the water out of the front like 'Old Faithful', gravity is going to pull some of the water back to the lowest point...the point of the present leak. Doubtful if there is an easy fix here.

    The only options that I see are:
    -Demo the back side of the Waterfall area until a point is reached where the liner can be 'pulled up' so the edge is higher than the waterfall weir.
    -Splice an extension piece onto the existing liner to gain height at rear of waterfall.
    -Demo the entire falls and rebuild using one of the currently available waterfall weir modules.
     
  9. I think I'm going to have to take the minimizing the loss approach. I'm going to stop the pump. Pull the stones back at the base. Pull the liner up best I can and try to seal off at the base but up as high as I can get it. Use larger flat stones to angle under the waterfall to force the majority of the water forward away from the base.

    Don't quite understand what you mean here. If you can raise the height of the liner edge at the back (and sides, if needed) of the waterfall, no sealant will be required.
