I ran a loooooonnnnngggggg hose up from our garden pump and into the "lake". It took almost 3 full 100' hoses to reach and 3 hours worth of pumping but it's full enough to fill in around the sides with dirt! I measured the depth and it is about 32" at the deepest part to ground level so at it's current level I would say it's at least 2' deep everywhere. When it start raining it should be full nearly to ground level so this should be good. Now I really need to pay attention around the edges because my models aren't water proof!
