The Niobrara River is where six major biomes converge to form a rich diversity of flora and fauna. Threats to the river arise from fire exclusion leading to the expansion of ponderosa pine into grassland area, changes in microclimates, the spread of invasive plants and the high volume of visitors during peak periods. — Niobrara National Scenic River Resources and…

A map shows that land use in the Ohio River Basin is dominated by developed, forested and cropland areas. Diagram from — Ohio River Basin Land Use

A conceptual diagram illustrates the dates and locations of different Mississippi River Report Card workshops. The workshop process is used to bring different groups together to strengthen the report card and promote broad prospectives, dialogue and collaboration. — Mississippi River Report Card Workshop Timeline

The diagram lists potential indicators for the Ohio River Basin that were generated at the workshop. The goals listed in this diagram are representative of the things people value in the Ohio River Basin watershed. — Potential Indicators for the Ohio River Basin

The Lower Mississippi River Basin supports a diversity of uses, dependent upon both natural and human engineered systems. This conceptual diagram illustrates the main threats and key features of the river basin. — Threats and Features of the Lower Mississippi…

Lower Mississippi land use is dominated by developed, forested and cropland areas, and has the largest proportion of wetlands of the entire Mississippi River Basin. — Lower Mississippi Land Cover Map

Several connections were made at the Lower Mississippi River Basin workshops. These connections will be used to develop a basin-wide report card for the watershed. — Lower Mississippi Workshop Connections

The Chesapeake Bay watershed received an above average annual amount of precipitation in 2013. This accompanied degrading conditions in some regions of the Chesapeake Bay watershed and improving conditions in others. — Chesapeake Bay Watershed Percipitation Map 2013

Unsustainable fishing and aquaculture practices have put pressure on the Chilika Lake ecosystem. Dead fish thrown back into the water contaminate the lake while shrimp pens trap sediment and kill juvenile fish. — Chilika Lake Fishing and Aquaculture Pressures

Chilika Lake Sedimentation

Improvements in water quality can be counteracted by changes in nutrient sources and land-use practices. Increased nutrient loads from stormwater and intensified agriculture often overwhelm the positive effects of best management practices. — Counteracting Factors Impacting Best Management…

Emergent wetland species are planted in a buoyant matrix that floats at the water surface. The roots of these plants grow through the matrix and take up the nutrients they need to grow directly from the water, potentially decreasing nutrient concentrations. — Floating Wetlands Structure and Impact

Excess nutrients will result in increased chlorophyll and turbidity, limiting the amount of light that reaches benthic sediment. Light is essential for healthy submerged aquatic vegetation growth. — Light and Dark Conditions Impact on Submerged…

Gutters and downspouts installed onto buildings direct rainwater from roofs to rain gardens. Plants with deep root systems encourage stormwater infiltration and absorbs excess nutrient runoff. — Multiple Benefits of Rain Gardens

Coastal wetlands that are protected from erosion have an adequate sediment supply to build upwards, and will likely be more resilient to the effects of climate change. — Coastal Wetlands Resilience to Climate Change…

Diagram depicting Human-caused and natural vulnerabilities of Chesapeake Bay to climate impacts. — Human-caused and natural vulnerabilities of…

A diagram that details a timeline of the catalytic converter and its functions. — Catalytic Converter Diagram

Simplified conceptual diagram of the water cycle and major sources of nitrogen, phosphorus, and sediment pollution to the Chesapeake Bay. — Groundwater Diagram

Inorganic Nitrogen in Chesapeake Bay Watershed…

A diagram depicting the effect that light conditions have on SAV and the trapping of nutrients. — Nutrient Trapping Diagram

The Chesapeake Bay watershed’s population is growing quickly. The watershed is currently home to 17.5 million people, and this number is projected to reach 20 million by 2030. — Population Map Chesapeake Bay Watershed

A diagram showing best management practices required to target the numerous sources and delivery pathways of excess nutrient loads. — Targeted Practices Diagram
