emergency horse watering in drought

Summer hotter and dryer than normal, water sources gone. We need emergency donations for horse water, gas to transport water, more horse troughs and a potable water tank truck.
Spring rains never came so all normal water sources dried in June. We are spending over $50 per day to buy water at $.01 per gallon and haul over 2000 gallons each day for the horses. We need emergency donations for expenses, to purchase a potable water tank truck, and to find a rental pastures that have constant water and transport horses to more safety. Some mares have foals and need much more water to make milk.
