We held an initial workshop April 25, 2016 in Rio de Janeiro, Brazil, to begin production of a report card for the Guanabara Bay and its watershed. This newsletter summarizes the discussions with environmental and social scientists, engineers, and government officials who developed a first draft of the indicators and reporting regions for the assessment of Guanabara Bay and its river basins.

In 2015, the Chester River received an overall grade of C+. CRA's Chester River Report Card is the product of tremendous volunteer effort and scientific analysis. The Chester Tester Citizen Scientists collect data at 27 stream sites twice monthly, year round. Our Riverkeeper and Watershed Manager collect samples from the mainstem of the Chester River from Eastern Neck Island to Crumpton.

The Department of the Interior Climate Science Centers (CSCs) and their managing organization, the National Climate Change and Wildlife Science Center at the U.S. Geological Survey, have chosen the emerging climate science field of Ecological Drought as a research focus area. This newsletter highlights the outcomes of a two-day workshop held in Fort Collins, Colorado, as part of a series of meetings at each of the nation’s eight CSCs.

New York Harbor is a large, iconic and complex body of water. The harbor is an important part of New York City and its millions of residents, and has been massively changed by human activities. These changes have altered the shorelines, water flow, plants and animals of the harbor. These drawings of New York Harbor help explain what is happening below the water surface—a look inside.

Ecological restoration of the Chesapeake through the Chesapeake Bay total maximum daily load (TMDL) requires the reduction of nitrogen, phosphorus, and sediment loads in the Chesapeake watershed because of the tidal water quality impairments and damage to living resources they cause. Within the Chesapeake watershed, the Conowingo Reservoir has been filling in with sediment for almost a century and is now in a state of near-full capacity called dynamic equilibrium.

George Washington Memorial Parkway was developed as a scenic parkway to help preserve the Potomac River Gorge and shoreline while serving as a memorial to the first President of the United States, George Washington. The Potomac Gorge is one of the most significant natural areas in the United States, and is home to more than 400 occurrences of over 200 rare species and communities.

The development of the first Ecosystem Health Report Card for Laguna de Bay, the largest in-land body of water in the Philippines, was funded by the Global Environment Facility (GEF) and jointly implemented by the Partnerships in Environmental Management for the Seas of East Asia Resource Facility (PRF) and the Laguna Lake Development Authority (LLDA).

Reduction of suspended sediment (SS), total phosphorus (TP), and total nitrogen is an important focus for Chesapeake Bay watershed management. The Susquehanna River, the bay’s largest tributary, has drawn attention because SS loads from behind Conowingo Dam (near the river’s mouth) have been rising dramatically. To better understand these changes, we evaluated histories of concentration and loading (1986−2013) using data from sites above and below Conowingo Reservoir.
