#### Future of Aquatic Flows: A data-driven framework to inform projections of aquatic flows in the Northeast

As climate change is impacting water resources and aquatic ecosystems, there is a great need for natural resource managers to assess adaptation measures in a holistic manner. This can be done by integrating model predictions of climate, hydrology, and ecosystems with observational data to better refine estimates of conditions on-the-ground; however, it can be challenging to combine these different

#### Enhancing a Spatial Planning Tool to Inform Management of Reservoir Fisheries, Stream Flows, and Societal Water Needs in the Red River

Ensuring the long-term sustainability of water resources requires careful stewardship of water for societal uses (i.e. municipal, agricultural, and industrial sectors) and also for the many other benefits that aquatic ecosystems provide to humans. In particular, reservoir fisheries and river ecosystems provide a range of economic, cultural, and recreational benefits. Maximizing the benefits that w

#### Anticipating Climate-Driven Spread and Impact of Multiple Interacting Invasive Species in the Columbia River Basin

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

#### Impact of Climate Driven Changes to Water Levels on Recreational Fisheries in the Northern Glaciated Plains

The Northern Glaciated Plains in the upper Midwest United States is a region where fishing generates millions of dollars a year for local and state economies. Maintaining these revenues requires the management of fish populations that are popular and accessible (e.g. boat ramps, public land access) to anglers. Fisheries throughout the world are currently undergoing unprecedented changes to water l

#### The Combined Effects of Seasonal Climate and Extreme Precipitation on Flood Hazard in the Midwest

The Midwest has experienced some of the costliest flooding events in U.S. history, including many billions of dollars during the past decade alone. The Midwest’s susceptibility to flooding has been exacerbated by a long-term increase in total precipitation and extreme rainfalls, with the 2010s being the region’s wettest decade on record Climate models strongly indicate that these recent trends w

#### Identifying Thermal Refugia for Brook Trout Climate Adaptation in Coldwater Streams

Climate change is making coldwater stream fish and their habitats more vulnerable than ever. In the Midwest, warming stream temperatures threaten recreational fishing for brook trout in their native range around the Great Lakes. To ensure that brook trout populations will persist into the future, it is crucial to focus management on areas where brook trout populations are most resilient, and to co

#### "Climate-smart" fisheries and aquaculture to support resilient aquatic ecosystems in Vietnam

The Vietnamese government has committed to mitigation and adaption in support of the Paris Agreement. Implementation of Vietnam’s Nationally Determined Contribution (NDC) to adaptation involves “prioritized adaptation actions for the period 2021-2030” to address “institutional, policy, financial, and human resource and technology gaps.” Of particular relevance, the NDC highlight the need for focus...

#### A guide to modeling low flows and intermittent streams in the Pacific Northwest

As droughts become more frequent, there is a growing need to understand how drought impacts streamflow permanence. Intermittent streams, or streams that go dry at some point during the year, are found in all ecoregions and represent over half of the global stream network length. As stream intermittence increases, there will be implications for both aquatic and terrestrial wildlife communities, lan

#### Future of Aquatic Flows in the South Central U.S.: Toward Sustainable Water Management in the Mississippi River Basin

The greater Mississippi River Basin (MRB) is the largest river basin in North America and the fourth largest basin in the world. The MRB encompasses 24 terrestrial ecosystems, providing habitat for 100 species of mammals, reptiles, and amphibians Its floodplain supports 40% of the waterfowl and wading birds in North America, and the MRB’s rivers transport 40% of the nation’s total exports.

#### Climate-Adaptive Population Supplementation (CAPS) to Enhance Fishery and Forestry Outcomes

Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of species fo
