The Bonnet Carré spillway (BCS) is a flood-control structure along the Lower Mississippi River designed to prevent flooding in the city of New Orleans by diverting excess water into the nearby Lake Pontchartrain estuary. Alarmingly, the BCS was opened as many times over the past decade (2011–2020) as it had been over the six prior decades combined (1951–2010), with devastating effects on the estua

Managing water resources in arid regions is increasingly important in the face of more frequent droughts and desertification that is occurring with climate change. These challenges of climate change intersect with potential environmental contamination from naturally occurring sources and legacy human activity (such as mining) and create a need for sustainable land and water management planning sol

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding, erosion, a

A persistent management question is whether current climate adaptation planning will remain robust when facing a growing number of invasive species. The concern is that current management strategies that focus exclusively on single invasive species and overlook climate-driven biological interactions, may lead to poor decisions. By delivering actionable science, this project directly informs specif

Climate adaptation planning provides a framework for Tribes to exercise sovereignty over wild resources important for the subsistence way of life and economic and cultural activities that are being impacted by climate change. The climate adaptation planning process includes identifying key resources that are currently being impacted by climate change, or that may be impacted in the future, as well

Wetland conservation in the Upper Mississippi River Basin (UMRB) is a priority for Federal, State, NGO, and Tribal land managers to support migratory bird habitat in Minnesota and Iowa. These wetlands, known as depressional wetlands, also provide ecosystem services associated with flood water storage and enhancing down-stream water quality by storing and processing nutrients. Understanding how con

Salt marshes are grassy wetlands that form along sheltered coastlines. These areas provide crucial habitats for many species of birds and other animals, in addition to recreational activities and economic opportunities. Marshes also protect the coast from storms and filter runoff from the landscape, ensuring cleaner and healthier coastal waters. As climate change causes sea levels to rise salt mar

Mountain meadows in the western United States provide key habitats for many plant and wildlife species, many of which rely exclusively on these areas. Mountain meadows are also treasured by the public and provide beautiful areas to view wildflowers and wildlife on public lands such as national parks. However, mountain ecosystems are expected to be disproportionately affected by climate change. The

Salmon are an important resource to the ecosystems, economy, and culture of the Kenai Peninsula, Alaska. However, salmon are under increasing stress due to warming water temperatures and decreasing stream flow. Groundwater is a major contributor to many streams that can help maintain fish habitat during low flows and contributes cooler water that regulates stream temperatures in the warm summer mo

Climate vulnerability assessments are tools that aid in understanding why specific resources are vulnerable to projected changes in climate. A recently developed online climate vulnerability assessment dashboard (https://www.usgs.gov/apps/CC_Vulnerability/) helps understand where vulnerability is projected to be greatest across watersheds in the Midwest United States (Illinois, Indiana, Iowa, Mich

Throughout the Pacific Northwest, invasive flora threaten river ecosystems and the communities that depend on them. Invasive plants harm water quality, occupy habitat for native species, reduce recreation opportunities, and damage infrastructure such as pumps and dams. Resource managers from federal, state, and local agencies, as well as local non-profits, spend hundreds of thousands of dollars on

Pacific salmon need cold water and quality habitat to survive. As climate change continues to increase river temperatures, effective methods to restore cool-water refuges and logjam habitats need to be determined. Many salmon habitat restoration projects in the Pacific Northwest have built engineered logjams (ELJs) to create deep, cool pools and reconnect rivers to floodplains to replenish cool gr
