In Spring Creek Park, Tomball, Harris County, Texas there is a monument to the Confederate Power Mill. This photo was taken March 19, 2006 near the site of the powder mill monument. When the powder mill exploded three men were killed. The site had a huge crater that subsequently filled with water to become a pond which became a local swimming hole. Unfortunately the swimming hole was unsafe and over the years some swimmers died, so the area was fenced-off (See fence behind the monument). The crater has now been made into a water retention area for the adjacent Powder Mill subdivision

On March 19, 2006 this photo was taken in Spring Creek Park, Tomball, Harris County, Texas. The town and park are in the NW corner of Harris County, near the Montgomery County line. Once inside the park, drive to the creek and you will see the monument near a fence at the far end of the only open field. On the other side of the fence is Powder Mill Subdivision. If you drive out of the park and make a half circle you will enter the subdivision, where you can look down on a modern-looking retention pond that was created from the crater caused by the explosion.
The monument mentions "Spring Creek County", but this county ceased to exist prior to the war but its name is used for the local historical society.
