You see them scattered all about Elm Lake — nesting boxes for the water fowl. This is box number 5. Elm Lake is a central focus of the Brazos Bend State Park in Texas. The water is scattered with little islets of reed and water grasses — perfect for ducks and wading birds. And they are there. Everywhere. This small, shallow lake simply abounds with wading birds and water fowl. Along with turtles and alligators. It is just a wonderful slice of nature that, alas, will soon be surrounded by Houston's burgeoning suburbs.
