Tiber Creek
Tiber Creek or Tyber Creek, originally named Goose Creek, is a tributary of the Potomac River in Washington, D.C. It was a free-flowing creek until 1815, when it was channeled to become part of the Washington City Canal. Presently, it flows under the city in tunnels, including under Constitution Avenue NW. == History == Originally named Goose Creek, it was renamed during the late 1600s by settler Francis Pope, who owned a 400-acre (1.6 km2) farmstead along the banks of the creek.
