#### Power analysis for detecting the effects of best management practices on reducing nitrogen and phosphorus fluxes to the Chesapeake Bay watershed, USA

In 2010 the U.S. Environmental Protection Agency established the Total Maximum Daily Load (TMDL) which is a “pollution diet” that aims to reduce the amount of nitrogen and phosphorus entering the Chesapeake Bay, the largest estuary in the United States, by 25 and 24% percent, respectively. To achieve this goal the TMDL requires the implementation of Best Management Practices (BMPs), which are acce

#### Lessons learned from 20 y of monitoring suburban development with distributed stormwater management in Clarksburg, Maryland, USA

Urban development is a well-known stressor for stream ecosystems, presenting a challenge to managers tasked with mitigating its effects. For the past 20 y, streamflow, water quality, geomorphology, and benthic communities were monitored in 5 watersheds in Montgomery County, Maryland, USA. This study presents a synthesis of multiple studies of monitoring efforts in the study area and new analysis o

#### Nutrient improvements in Chesapeake Bay: Direct effect of load reductions and implications for coastal management

In Chesapeake Bay in the United States, decades of management efforts have resulted in modest reductions of nutrient loads from the watershed, but corresponding improvements in estuarine water quality have not clearly materialized. Generalized additive models were used to directly link river flows and nutrient loads from the watershed to nutrient trends in the estuary on a station-by-station basis

#### Study of stream fishes provides new framework to monitor climate change in the Chesapeake Bay headwaters

Issue: The Chesapeake Bay Program (CBP) have identified four goals for actions toward change climate: • address the threats of climate change in all aspects of the partnership’s work; • prioritize communities, working lands, and most vulnerable habitats; • apply the best scientific, modeling, monitoring and planning capabilities; and • connect restoration outcomes with emerging opportunities. A...

#### USGS Part of New Federal Effort to Address Climate Change in the Chesapeake Watershed

Issue: The federal government will work together to implement the Chesapeake Executive Council Directive No. 21-1 Collective Action for Climate Change, recognizing that urgent attention is needed to confront the challenges that a changing climate poses to the Chesapeake Bay region. The Directive emphasizes the importance of the “…resiliency of the Chesapeake Bay Watershed, including its living...
