ok i have investigated the following 2 choices

1 dig a well cost $4200 (probably about $300 with a 1 1/2 hp pump) plus float valve.

2 a local from here near houston quoted an estimate of $1.00 per sq ft for a liner - seems high he ways my first call.

in addition i have looked at every post on this
web site concerning leaks and have come up with this list of causes.

1 dam not cored - would a good amount of bentinite solve this and where would one put it?

2 leaks at dam where original ground was and new dam dirt starts - again would bentinite solve it if it was applied where the dam is?

3 leaks 2 foot below the full water line (dont know if that one was just around dam or whole pond
- same question would bentinite solve this.

4 leaks around tree roots which i have 4 or 5 larger trees around pond but trees everywhere 180 degrees around back of pond. not sure what to do?

the pond is dropping 1 inch a day

i can buy bentinite for $6 dollars per 100 lb bag locally.

the pond is built in the side of a slite slop maybe dam part is 4 or 5 foot high. the circumference of pond is about 260 feet, figured as follows about 80+ in diameter times pie 3.1414.
the dam portion is about a hundred feet long.

takig into consideration the above how much bentinite is required? still trying to figure best way to approach.

thanks fellas
