LOWER HEIDELBERG TWP., Pa. - Some folks are getting a look at how the dam at Blue Marsh Lake functions.
A tour of the control tower in Lower Heidelberg Township on Thursday morning gave guests a behind-the-scenes look at the dam. It's a restricted area, so it's not something you'll see every day.
"They see the control room and they see how the water is flowing through and how we're able to transport the water, carry the water from the lake into the Tuelphocken Creek downstream," said Kathy Grim, natural resource specialist.
Control tower tours at Blue Marsh Lake are held about once a month.
