A blast hole that contains any amount of detectable water.

Where water depth is recorded on a dip sheet this is the depth from the toe of the hole to top of the water.

Water depth is measured by listening and feeling for the top of the ware using a dip rope and weight. This length is subtracted to give the water depth.

For example if the top of the water is measured at 22m and the hole depth is 28m then the water depth is 6m.
