Tom F,
I have a well with a 1.5 horsepower submersible pump . The well driller went 148 feet to good water. Driller said I was getting 50 gallons a minute and it does a fine job keeping my 1.25 acre pond full. Mine is an open flow well which means no pressure tank therefore no hydrants. When you turn the well on it goes straight to the pond. Another thing is I have a 2" schedule 40 pvc piping going from well to pond.
Hope this was helpful. One last thing, my well man came with excellent references and did wells for several of my friends.
