2017 Technical Addendum Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity and Chla

A total of seven addendum documents have been published by EPA since April 2003. Four addenda were published documenting detailed refinements to the criteria attainment and assessment procedures (U.S. EPA 2004a, 2007a, 2008, 2010) previously published in the original April 2003 Chesapeake Bay water quality criteria document (U.S. EPA 2003a). One addendum published Chesapeake Bay numerical chlorophyll a criteria (U.S. EPA 2007b). Three addenda addressed detailed issues involving further delineation of tidal water designated uses (U.S. EPA 2004b, 2005, 2010) building from the original October 2003 tidal water designated uses document (U.S. EPA 2003b). Finally, one addendum documented the 92-segment Chesapeake Bay segmentation scheme (U.S. EPA 2008) after refinements to the Chesapeake Bay Program analytical segmentation schemes were documented (U.S. EPA 2005) building from the original U.S. EPA 2004 document (U.S. EPA 2004b). This 2017 addendum is the eight addendum document developed through the Partnership and published by EPA.

Climate and Fisheries Bibliography - January 2017

Climate Change and Fisheries Research in the Chesapeake Bay

A compilation of fisheries-based climate
research and tools compiled by the
NOAA Chesapeake Bay Office
January 2017

This compilation of fisheries-based climate research and tools was compiled by the NOAA Chesapeake Bay Office. The contents of this document were compiled based on a review of both peer-reviewed and grey literature as related to the 2014 Chesapeake Bay Agreement Goal to “increase the resiliency of the Chesapeake Bay Watershed, including its living resources, habitats, public infrastructure and communities, to withstand adverse impacts from changing environmental and climate conditions.” This document is not intended to be an exhaustive list; recognizing that there are additional research and tool development under way within the region. This document will be updated on an annual basis.

Chesapeake Bay Species Habitat Fecundity Matrix

The Sustainable Fisheries Goal Implementation Team (Fisheries GIT) of the Chesapeake Bay Program was allocated Tetra Tech (Tt) time to support Management Strategies under the 2014 Chesapeake Bay Program (CBP) Agreement. The Fish Habitat Action Team under the Fisheries GIT requested Tt develop a matrix compiling information on habitat requirements, stressors, and threats for egg and larval life stages of lesser-studied species across the Chesapeake Bay.

Fish and shellfish in the Chesapeake Bay and its watershed rely on a variety of important habitats throughout the watershed. These habitats, which are key to sustaining fisheries, are being threatened by a suite of stressors and sources such as increased urbanization, poor water quality and climate change. Successful fisheries management depends on knowing what and where these important habitats are and addressing the potential and realized threats to their integrity. Tetra Tech will provide staff time and resources to develop products in support of the Fish Habitat Outcome and Management Strategy (http://www.chesapeakebay.net/managementstrategies/strategy/fish_habitat). As a first step the Management Strategy calls for compiling information on key species, their habitat requirements, habitat functions (generally spawning, nursery, and forage), and the threats or stressors to these habitats.

Species Habitat Matrix

The Sustainable Fisheries Goal Implementation Team (Fisheries GIT) of the Chesapeake Bay Program was allocated Tetra Tech (Tt) time to support Management Strategies under the 2014 Chesapeake Bay Program (CBP) Agreement. The Fish Habitat Action Team under the Fisheries GIT requested Tt develop a matrix of available habitat requirements, threats and stressors for lesser-studied species across the Chesapeake Bay.
