Indigenous Relationships with Waterways

Montgomery County is bordered by the Potomac River to the west and the Patuxent to the east. Several stream valleys—Rock Creek, Sligo Creek, Northwest Branch, and Watts Branch among them—lace the country’s interior. For thousands of years, Indigenous groups lived along these river and stream banks and traveled their waters. Among these groups were the ancestors of the Piscataway, who are now primarily based in Southern Maryland.

The word “Piscataway” means “where the waters blend.” Many of the “official” names now assigned to local waterways and places derive from the Algonquin language group, of which the Piscataway are a part. When Captain John Smith, an English colonizer, sailed up the Potomac in 1608, he recorded some of those names.

Potomac River—Patawomeck

Anacostia River—named for the Nacotchtank or Anacostans  

Seneca Creek—”a place of many rocks” or possibly derived from the Tsenacommacah, “densely inhabited Land”
