A neighbor passed along this US Department of the Interior document from 1977 titled “Washington DC’s Vanishing Springs and Waterways.”
I have not read this document, but notice on page 7 a rough map of DC’s “downtown areas’s original streams.”
Plus there is a looong description of the Tiber Creek.
In consideration of the recent neighborhood flooding — and not just in Bloomingdale! — I thought that Bates area residents might like to see where the Tiber Creek flowed.
