Hi nibaceta,
Trying to map water is very difficult. You will want to fly as high as possible and have very high overlap. Perhaps 80-90%. Ideally, you do not want images that only contain water. It is best if the images contain some land as it will greatly help calibrate the images. I hope this helps.
