Took detailed measurements and got new quotes from Western Liner and BTL.

The pond depth measures
a. 14.4’ at the north bottom to the top of pond liner (13.3’ to water line)
b. 13.2’ in the middle bottom to the top pond liner
c. 13.7’ at the south bottom to the top of the pond liner

Measurements are taken with a 300’ measuring tape and going from planned trench site on one side to planned trench site on the other side and letting the tape fall to the bottom of the pond in-between. (So, measurements already take into account pond depth). The water line will be 1' of elevation below the tarp, 3-4' away from the anchor trench.

The North South length of the pond (including the depth) measures 341’ in the middle.

The East West length of the pond (including the depth) varies from 220’ to 142’ going from the north to south.

I calculate this to be approximate 1 acre surface area.

Western Liners Aqua 30 RPE (warranty 10yr exposed, 20yr buried)

One piece Liner delivered (7500lbs): $29021
Geotextile 15' width around entire pond bank: $3069 (shipping included with the liner)

Installation options, for these options they would make the liner in 3 pieces and field seem
Edit: both of these options would be $3500 lower liner cost due to less material wasted with 3 panels.
Full install: $12,165
Supervisor only (he will supervise and do all field seems): $8,115

------------------------------------------------------------

BTL Aqua Armor 30 RPE (rated for 15yr exposed, I do not see any warranty)

One piece Liner delivered (7300lbs): $33,090
They did not send quotes for geotextile.

Installation option, for this options they would make the liner in multiple pieces and field seem
Supervisor only (he will supervise and do all field seems): $6,500 for expected 1 day install, $1,500/day each additional day.

I also sent a request to GSI for a quote but have not received a reply.

I am strongly leaning towards liner+15ft geotextile, that would give me about 9' of geotextile underwater to protect liner and prevent the overfill from sliding down. Another option would be a 18' geotextile that Western said they could make for me by seeming 12' liners together (12+6). That would be 12' of coverage but obviously be an added cost.

This project has gotten a lot more expensive than originally planned. I think I have $10k in dirt work, in additional to quite a few hours of my own time doing dirt work. I was originally thinking 1/2 acre and $20k build cost.
I assume I will also need an aeration system (2k?). Plus dock, boat ramp, landscape work, fish structure, fish stocking, well, the list goes on and on!
