Wednesday, June 21, 2023 from 1:00pm - 2:30pmNontidal Network Workgroup August 2023 Meeting
Wednesday, August 16, 2023 from 1:00pm - 2:30pmScope and Purpose
Manage Chesapeake Bay Program (CBP) nontidal water quality monitoring networks and coordinate monitoring and assessment with additional networks to address the 2014 Chesapeake Bay Watershed Agreement.
The CBP currently manages several water quality monitoring networks including a watershed network. Consistency of station operations across the watershed in the current 123 station network has its foundations in the 2004 Memorandum of Understanding signed by the State of Delaware, the District of Columbia, the State of Maryland, the State of New York, the Commonwealth of Pennsylvania, the Commonwealth of Virginia, the State of West Virginia, the Interstate Commission on the Potomac River Basin, the Susquehanna River Basin Commission, the Metropolitan Washington Council of Governments, the United States Environmental Protection Agency, the United States Geological Survey and the Chesapeake Bay Commission regarding cooperative efforts for monitoring and assessing water quality in the streams and rivers of the Chesapeake Bay watershed.
The networks are complex with multiple partners collecting data. There is additional monitoring and analysis that needs to be conducted to address the outcomes of the 2014 Bay Agreement, and its evolution beyond 2025. The Workgroup focuses on 1) sustaining long-term consistency in the network stations’ distribution and field, lab and analysis operations, 2) tracking data collection completeness each season on an annual basis, 3) sustaining data quality assurance and analysis methodology, 4) evaluating the utility of new sensor applications, 5) updating analysis methods, 6) synthesizing and reporting on nutrient and sediment loads and trends, 7) targeting management investments to improve return on investment with best management practices, 8) providing a platform to address network operational issues, 9) providing criteria and guidance to support network optimization, and 10) supporting the value of watershed monitoring in data driven decision making.

Interim Guidance for Nontidal Network (NTN) WY2013 Field Blank and Duplicate Sample Collection
INTERIM GUIDANCE FOR NONTIDAL NETWORK WY2013 FIELD BLANK AND DUPLICATE SAMPLE COLLECTION
Draft Jan. 28, 2013
The Nontidal Data Upload and Evaluation Tool (DUET) will include pre‐programmed subroutines to generate
statistical measures of the completeness, precision and bias of nontidal network (NTN) monitoring data. These
statistics will enhance the ability of end users to comprehend, use and defend the data.
Programming for the required or “expected” number and types of water quality (WQ) and quality control
(QC) samples, as originally determined by the Nontidal Workgroup, has been difficult due to: 1)
insufficient detail in the guidance and 2) implementation differences among agencies, such as the
collection of additional WQ samples and different types of QC samples.
Therefore, the following “interim” guidance is intended to overcome these difficulties for the collection
and reporting of WY2013 nontidal data.
