Approximately 48,878,000 gallons.
1 acre = 43560 sq.feet. 1 foot deep water over an acre is 43560 cubic feet, which is 325851.4 gallons in 1 foot deep. If it is 1 inch deep (1/12 foot) then it is 27154.3 gallons in 1 inch deep.
It depends on the depth of the water. Assuming the water in one inch deep, there would be about 13,577 gallons of water in the half acre.
A 1000 acre lake that is 7 feet deep (uniformly) will have 7000 acre feet of water in it. An acre foot is an acre of water one foot deep, and the unit is used to measure reservoir water capacity. The conversion factor is that one acre foot equals about 325,851.5 gallons. The lake in question is holding 7000 times 325,851.5 gallons of water.
The answer will depend on how deep the lake is!

Approximately 8,146,286 gallons of water.
If the pond is uniformly 6-feet deep it would contain about 1,955,109 gallons of water.
Approximately 977,553 gallons of water.

A 25-acre pond that is uniformly 6 feet deep will hold about 48,877,714 gallons of water.
We have no way of knowing that. It's really going to depend on how deep the water is. For example ... -- If the water averages 6-ft deep, then there are 21,544 gallons of water in the pool. -- If the water averages 1-inch deep, then there are 299.2 gallons of water in the pool. -- If the 480-sq-ft pool is empty, then there are zero gallons of water in it. It might help you to know that it'll be roughly 300 gallons per inch of depth, and you take it from there. Note: If the bottom is sloped, then that's a whole different problem.
One acre-foot is 325,851.4 US gallons of water.
