Summary

This metadata record document contains 7 tables used to assess factors influencing long-term water quality changes in the Gwynns Falls, Baltimore, MD, 1998-2016. Included are daily discharge measurements (source: United States Geological Survey (USGS), 2016), weekly nutrient sampling concentrations (source: Baltimore Ecosystem Study (BES), 2015), and approximately monthly bacteria, ammonia, TKN, and TSS sampling concentrations (source: Baltimore City Department of Public Works (DPW), 2016; Baltimore County Department of Environmental Protection and Sustainability (DEPS), 2016). Annual loads were calculated for each Gwynns Falls subwatershed from the discharge measurements and sampling concentrations. Green infrastructure data (Best [...]

Purpose

The data were compiled to assess long-term water quality changes and to identify the main factors (e.g. green & gray infrastructure, land cover change, climate change) influencing water quality changes. Appropriate use of the data includes studying water quality, infrastructure, land cover change, and/or climate change in the Baltimore region.
