Yes, except for fish. Padre Dam's drinking water does contain chloramines which is a combination of chlorine and ammonia that serves as a disinfectant for your water. Chloramines kill bacteria and will be harmful to fish. When you use your drinking water for fish tanks, you will need to purchase water treating products from the local pet supply store that will neutralize the chloramines before putting your fish in the water. Chloramines do not affect other animals and is safe for them to drink.
