Region Info

The Upper Eastern Shore watershed drains approximately 1,300 square miles of land. This area includes portions of Cecil, Queen Anne's, and Talbot Counties and all of Kent County. Major bodies of water include the Chester, Elk, Bohemia, Sassafras, and Northeast Rivers, and Eastern Bay. Almost half of the land in the Upper Eastern Shore watershed is agricultural, and a third of the land is covered in forest. Major towns in the area include Elkton, Chestertown, Grasonville, Centreville, and North East. Census population for the watershed in 2000 was 125,000. There are eight major wastewater treatment plants in the watershed. (Based on MD DNR Tributary Strategy Report by Aadland et al., 2007 and updated 2000 land use classifications).

The EcoCheck report card has three main sections: Overview, Region Summaries, and Indicators/Indices.

Click the next (>>) button above to get a guided tour of some of the key features of the report card card website.

This map shows the Health Index grades for all the reporting regions, but mousing over each region also provides a text summary and clicking will direct the user to the region summary page with more details about the health of that region.

The region rankings table provides an easy way to visualize the Water Quality Index (WQI), Biotic Index (BI), and overall Bay Health Index (BHI) for all regions. Once again, mousing over provides extra information - try it yourself and see what is displayed. Region names, and indicator icons also serve as navigation links.

The comparison graph allow users to compare the current report card to previous year's scores. Mousing over provides actual percentages and bars provide a direct link to the region's summary page.

Now you're at the region summary page for the Overall Bay. This page details the scores for all the individual indicators, as well as a dynamically generated conceptual diagram (please scroll down the page to view). Even this diagram has more information onmouseover, and has direct links to the detailed indicator pages. There is also a vector (SVG) version of the diagram available for download so you can edit this in your favorite illustration software.

The trends graph shows all the indicators and indices for the selected region since 1986. You can dynamically turn on and off each of the indicators to show only the data you are most interested in. Mousing over the graph shows percentage scores and you can zoom in for finer detail in certain time periods. There is also a fully editable vector (SVG) version of the graph available for download, along with an Excel spreadsheet of the data.

This is the threshold map for Chlorophyll a. This map is zoomable and panable and also available in fully editable vector (SVG) and JPG versions.

The trends graph on the indicator pages shows the indicator and indices data for each region since 1986. By default, only the Overall Bay region is displayed, but you can turn on as many of the other regions as you wish.

The watershed stream health page has several tabs, but the key one is the interactive Google maps version of the data.

Please wait while the map loads and then test out the ratings toggle options and the "zoom to area" functionality (click on the magnifying glass and then click and drag to select the are to zoom to).
