What is boschers dam?

As an AI language model, I do not have access to current information. However, based on my knowledge, I can tell you that Boscher's Dam (also known as Bosher's Reservoir), is a man-made lake located in the James River Park System in Richmond, Virginia, USA. Built in the early 1900s, the dam was initially designed to provide power to a nearby paper mill but is currently used for recreational purposes such as fishing and kayaking. The dam is listed on the National Register of Historic Places and is a popular destination for outdoor enthusiasts in the Richmond area.
