Introducing the Hooffs Run Watershed.

Introduction

This blog is dedicated to the study of the Hooffs Run Watershed in Alexandria, VA, as part of the Virginia Tech Graduate Course Watershed Stewardship (NR 5264).

The City of Alexandria has identified and mapped 10 watersheds within the city limits, which all flow in to the Potomac River, then onward to the Chesapeake Bay.

Key geographic features of the Hooffs Run Watershed include the southwest quadrant of Old Town, George Washington Masonic Temple, Braddock Road metro station, and approximately half of the suburb of Del  Ray.
