Overview

The U.S. Geological Survey is a participant in the Baltimore Ecosystem Study (BES), an urban Long-Term Ecological Research (LTER) Project, which is a collaboration of federal, state, local, non-profit, and academic research sponsored by the National Science Foundation.

BES scientists conduct many investigations of the urban ecosystem, but all address one or more of three central questions. Studies by USGS address two of these questions:

  1. "What are the fluxes of energy and matter in urban ecosystems, and how do they change over the long term?"

  2. "How does the spatial structure of ecological, physical, and socio-economic factors in the metropolis affect ecosystem function?"

Hydrologic investigations are led and conducted by a team of Principal Investigators and Collaborators, including Mike Koterba, Ed Doheny, and Gary Fisher of USGS, Larry Band of the University of North Carolina, Ken Belt of the U.S. Forest Service, Andy Miller and Claire Welty of the University of Maryland, Baltimore County, and Jim Smith of Princeton University. Other BES investigators collaborate on various projects that integrate closely with their own disciplines.

USGS operates a basic network of hydrologic data-collection stations in collaboration with BES. Analysis of data from these stations provides fundamental information used by any BES researchers. USGS is working with other investigators and potential collaborators to support and develop scientific investigations, including topics in meteorology, streamflow, ground water, water quality, toxic substances, and sediment. USGS is investigating alternative techniques to measure peak streamflow in urban drainage systems, which are quite unlike natural drainage systems. A promising and important area for research that USGS and the UMBC Center for Urban Environmental Research and Education (CUERE) are pursuing is in urban ground water, where even the fundamental relationships between urban water-resources infrastructure, ground-water flow, and urban stream baseflow are not known.

An excellent overview of BES is in the Fall 1999 issue of Maryland Marine Notes.

Water-Resources Investigations

The Gwynns Falls Watershed is the primary focus for BES activities. Following is a summary of available water-resources Data and related information.

The Gwynns Falls Watershed is a part of the Gunpowder-Patapsco Hydrologic Unit. General information on the Hydrologic Unit is available from the EPA Surf Your Watershed and from USGS Science in Your Watershed. It is included by the Maryland Chesapeake Bay Tributary Team in the Patapsco/Back River unit.

Streamflow Data

Streamflow and water-quality Data are routinely collected by BES participants at continuous USGS stream-gaging stations. USGS stream-gaging stations are operated in cooperation with local, state, and federal agencies, including financial support.

There are four longitudinal stations along the Gwynns Falls:

Investigations are being conducted at four small watershed stations:

Other stations where BES data are being collected:

BES data have also been collected at the following inactive USGS stations. These are not shown on the above map.

Discontinued USGS stations in the Gwynns Falls Watershed include the following. These are not shown on the above map.

Data collected by USGS at these and other historical stations are available from the National Water Information System (NWIS) and the Instantaneous Data Archive (IDA). Daily data and statistics are generally posted once per year after they are reviewed and validated for each Water Year (October 1 to September 30). Instantaneous-values data (5 or 15-minute discrete record) are not available through NWIS but approved data can be obtained from IDA. Provisional data, those that have not been fully evaluated for approval and public release, can be obtained for the last 31 days at real-time stations through NWIS. Requests for any other data should be made directly to USGS.

USGS operates many other stream-gaging stations in the Baltimore area that may provide data for investigations of urban hydrology.

Groundwater Data

An inventory for Gwynns Falls and vicinity was prepared by USGS of existing wells and geotechnical data from the USGS NWIS, the Maryland Well-Permiting System, and bridge plans obtained from the Maryland State Highway Administration, Baltimore City, and Baltimore County.

The inventory, which was conducted in 2001 and 2002, compiled data for 1,683 wells from NWIS, 1,154 wells from permits, and 212 bridge construction borings. The following figures were prepared by Mike Maguire of CUERE and show the distibution of existing well data.
