Tools include the Chesapeake Stat dashboard, Bay Barometer, BayStat, and the Watershed Implementation Plan tracker.For PA watershed groups in the Susquehanna or Potomac drainages, these tools provide context for local work, baseline data for grant applications, and tracking of nutrient and sediment reduction progress against state milestones.Especially useful for showing funders how local work fits within the broader Bay TMDL framework.
