The Patapsco Valley Watershed had been the site of a number of fishway construction projects at dams, which DNR now says have not lived up to expectations. All of the dams except Daniels have been removed, restoring free flow of the river, and the Daniels dam is scheduled to be removed.
If you regularly bird in the PVSP, consider getting a trail map. A PVSP complete trail map is recommended for travel away from the river. The map is available for purchase at the Hollofield area Headquarters Building, the Avalon Visitor Center, and the Marriottsville contact station (McKeldin area).
