2010 article, but all have disappeared now.
This is one of the inflow controllers. I wish it was intact and wish I knew how it worked.
My friends and I came across another building that we had not explored before.
This building contained the remains of two huge air compressors. I am still not sure exactly how the compressed air was used, but it had something to do with the pneumatic controllers and the chart strip recorders.
This viewing platform was once used by tourists who visited the site. In the 1960s, the Basin Model was a popular tourist attraction (as was the Waterways Experiment Station before 9/11). I have read that many of the former German prisoners of war who worked on the site in World War II came to see the functioning model.
The model is a peaceful place on a quiet Autumn afternoon. Visit it soon before the buildings and concrete terrain elements are completely overgrown.

UPDATE JULY 2017: A volunteer organization has been formed to clean and clear the site and develop it as an education/interpretive center. Readers interested in participating in the cleanup work, please contact:
