My very first post - bear with me! Our current pond has been enlarged by raising the dam and should be 2 surface acres with maximum depth at dam of 14'. However, due to lack of any runoff rain in our part of Illinois, we are drilling a well to supplement pond. Our well guy has suggested a 1 1/2 hp submersible pump the will give us 20 GPM. The well will be 270' into an aquafer that is used for irrigation. But I know I've read some posts that mention pumps that give 50+ GPM. Is that something that we should be looking into instead? Any insight is really appreciated.
