i think its about 2 gallons. i took a pic of the water level befor i left and ill mark what it is when i get back...if any. then ill set out another n see how long it takes to be empty so ill know how long its gone without water...i been checkin the weather its gettin down there and its been pretty dry....and people dont usually pull into drives down there where i was at and if they did it would look like some garbage in the yard. its a construction zone so it will fit in :jointsmile:
