We are making a video about the water habitat. There are two ponds at the park. The bigger pond has an island that is a nesting place for mallard ducks. There is a waterfall at the big pond. There is a little pond without an island.
Water is pumped from the little pond to a pool above a waterfall.
The water spills from the pool down to the big pond. This makes the waterfall. There is a spillway from the big pond to a stream that goes down to the little pond. Since 1993, there have been many changes in the pond habitat. The island was getting smaller.
