We installed our 3rd 24' livestock water tank this week on the ranch.  It will hold 8400 gallons of water--this replaces 5 smaller old tanks that held a total of 6700 gallons of water.  However 2 of the old tanks were completely disintegrated and 2 others leaked quite badly inspite of our efforts to seal them.  So we only had about 2000 gallons of effective water storage at this mill.  Our rotational grazing system that we now practice requires running large groups of cattle for short periods of time in a pasture, so this increased water supply will allow us to get by when the wind doesn't blow for several days to pump water.
