< Sidebar: >
Valley Creek is cleaner than at any time in the last 300 years. Threats to the creek have changed over time. Once polluted by raw sewage and toxic chemicals, today sediment and warm temperatures degrade aquatic habitat, a result of paving and building on lands upstream of the park. With less open land where rainwater can sink in, there are increasingly frequent and intense floods. Floodwaters are warm, contain sediment from collapsing stream banks, and wash in roadway pollutants such as oil. Raging waters also wash out archeological resources along the creek, and even threaten the Covered Bridge and Washington’s Headquarters.

More about this marker. The background of the marker contains a 19th century photo of Valley Creek with Washington’s Headquarters nearby. It has a caption of “In the 18th and 19th centuries, this scene looked very different. Iron works, mills, and other industries were located along the stream. These were ‘working waters.’ Dams in several places provided water power and also created large ponds where now you see flowing water. The land on either side of the creek below is composed of sediments that settled behind one of these dams.
In the 19th century, a mill stood between Washington’s Headquarters (at upper left) and Valley Creek. Like

A picture of a trout on the left of the marker has a caption of “In spite of its location in an urbanized region, Valley Creek supports a naturally reproducing population of wild trout. Numerous springs from the limestone bedrock along the creek’s length provide a steady supply of the cool water that trout and native stream species need.
