Established in 1985, the Jug Bay Wetlands Sanctuary originated from Anne Arundel County's efforts to acquire and preserve land along the Patuxent River beginning in the early 1980s. Five years after its establishment, in 1990, the sanctuary earned designation as a component of the Chesapeake Bay National Estuarine Research Reserve System, further solidifying its role in regional conservation and research. Beyond its natural significance, Jug Bay holds profound archaeological importance. Evidence of Native American habitation in the area dates back as far as 11,000 years, with numerous archaeological sites, including the notable River Farm and Pig Point sites, revealing a rich history of human presence along the Patuxent River. This deep historical context adds another layer of intrigue to the sanctuary's diverse offerings.
