2011 Chesapeake Bay Report Card (Page 1)

2011 Chesapeake Bay Report Card

Bill Dennison, Caroline Donovan, Jonathan Kellogg, Alexandra Fries ·
17 April 2012

This report card provides a transparent, timely, and geographically detailed assessment of Chesapeake Bay. The overall health of Chesapeake Bay, determined using water quality and biotic indicators, declined slightly in 2011. The overall grade of D+ was a decrease for the second year in a row, down from a C- in 2010. Only two reporting regions, the Patapsco and Back Rivers, and the Lower Western Shore (MD), had improved grades in 2011.

Chesapeake and Atlantic Coastal Bays Trust Fund

Sara Powell ·
29 February 2012

The Chesapeake and Atlantic Coastal Bays Trust Fund was created in 2007 in an effort to reduce nutrient and sediment pollution to these bays. The Trust Fund has focused its financial resources on the implementation of effective non-point (i.e., diffuse) source pollution control projects in high priority watersheds. This newsletter details examples of projects supported by the Trust Fund including stream channel restorations, stormwater retrofits, and cover crops.

Bacteria sampling and data analysis protocol addendum for Mid-Atlantic tidal tributary indicators (Page 1)

Bacteria sampling and data analysis protocol addendum for Mid-Atlantic tidal tributary indicators

Wicks EC, Kelsey RH, Fries AS, Kellogg JP ·
13 January 2012

This document provides guidelines for the successful production of tidal ecosystem health report cards. Specifically, this document serves as an addendum to the Sampling and data analysis protocols for Mid-Atlantic tidal tributary indicators which develops a clear and consistent protocol for the identification, collection, and analysis of the indicator of bacteria.

Channel head locations in forested watersheds across the mid-Atlantic United States: A physiographic analysis

Julian JP, Elmore AJ, and Guinn SM ·
2012

Channel heads are the beginning of river networks and thus knowing their location is important in assessing water resources and health threats to fluvial ecosystems. Despite their importance, most channel heads are unmapped. Remote sensing technologies have not yet proven effective under forested canopies, suggesting that predictive models of channel head locations are the best solution to the impracticality of field-mapping the millions of these features that exist in the U.S. alone.

A citizen's guide to the Chesapeake Bay TMDL

Melissa Andreychek, Sara Powell, Caroline Donovan ·
20 May 2011

Residents of the Chesapeake Bay watershed depend upon a healthy Bay for food, recreation, and commercial enterprises. But the ways in which we use the watershed’s lands—from driving our cars to spreading fertilizers—impact the health of the Bay’s waters. Wastewater treatment plants, agricultural operations, and urban runoff are major sources of the nitrogen, phosphorus, and sediment pollution that threaten the Bay’s health.

2010 Trust Fund Water Quality Monitoring Strategy (Page 1)

2010 Trust Fund Water Quality Monitoring Strategy

Jane Hawkey ·
10 May 2011

This Monitoring Strategy was designed to identify nutrient reduction efficiencies of best management practices (BMPs) and provide information to determine what type of monitoring is needed by Trust Fund recipients to evaluate the effectiveness of BMP implementation. The main objective is to provide a comprehensive protocol that serves all water quality assessment needs when monitoring urban and agricultural non-point nutrient and sediment fluxes.

Chesapeake Bay Report Card 2010

Bill Dennison, Heath Kelsey, Caroline Donovan, Sara Powell ·
27 April 2011

This report card provides a transparent, timely, and geographically detailed assessment of 2010 Chesapeake Bay health. The overall health of Chesapeake Bay, assessed using water quality and biotic indicators, declined slightly in 2010. The overall grade decreased from a C in 2009 to C- in 2010. Only two reporting regions (James River and York River) had improved grades in 2010, three were unchanged, and nine declined.

Expanding the diversity of the Mid-Atlantic Tributary Assessment Coalition

Sara Powell, Caroline Donovan, Melissa Andreychek, Heath Kelsey, Bill Dennison ·
18 November 2010

Since the 2006 release of the first EcoCheck Chesapeake Bay report card, environmental report cards have gained increasing popularity and recognition as a public-friendly and scientifically sound method for reporting the health of a waterway. Recently, a number of watershed organizations in the Mid-Atlantic region have begun producing their own tributary-specific report cards.

Blue Crab Status Report (Page 1)

Blue Crab Status Report

Sara Powell, Heath Kelsey ·
12 October 2010

Blue crabs are one of the best-known and most celebrated symbols of the Chesapeake. Their populations in the Bay have hovered near historic lows for much of the last decade, but have recently begun to show signs of improvement. This newsletter reviews the current status of the blue crab population in the Chesapeake Bay as well as the management systems in place to monitor and protect this iconic species.
