The overflow water from Tempe Town Lake creates a sort of marsh land at the west end of the lake. It's perfect environment for all kinds of birds. Tomorrow I'll show you one of the birds I saw there.
There were lots of questions yesterday about the inflatable dam that creates the lake. The lake is located in a dry river bed. The river is dry most of the time but if we have wet weather in the mountains that surround Phoenix, the river can run and has on many occasions. Anything built in the river bed or on the shores of the river has to take into account flooding from time to time. The dam was built so that it can be deflated in flood times in order to allow the river to flow its natural course.
