I want to grow crops like corn + other vegetables on 1/4 acre. Our well produces 7 gpm. - How much water is needed per day? (This is in CA with zero rain in summer.) - The property borders a creek, so how could I take water straight out the creek? The garden area is about 200 yards from the creek. Would there be problems with mud etc. if we have a tank because it runs low in summer. Thanks in advance for advice.
