The rivers of the Pacific Coast states are heavily altered by dams and diversions ( over 1,400 dams in California, 1,039 in Oregon, 1,174 in Washington ). The dams generally are used for hydropower generation, irrigation, and transportation, all essential to supporting the region’s extensive agricultural and manufacturing (aluminum, aircraft, shipbuilding) industries. Dams create problems for fish such as salmon and steelhead by interrupting or halting their migration from the Pacific to upstream habitats and killing large numbers of young salmon (smolts) as they move downstream through powerhouses or spillways. Numbers of salmon and steelhead have declined drastically from historic levels, and many populations...

Dams and other barriers are having a significant effect on fish habitat in the Upper Midwest. More than 3,700 dams have been constructed on Wisconsin’s warm water streams. Similarly, there are 2,500 listed dams in Michigan and likely a similar number that are not in the dam safety database for that state. In the Lake Michigan watershed alone, dams, culverts, and road crossings that impede fish migration have reduced nearly 19,000 miles of accessible stream habitat to only 3,300 miles. With many Great Lakes fish species using tributaries as spawning and nursery habitats, these barriers are a significant factor impairing the full recovery of fish populations in the Great Lakes. Similar fragmentation occurs on other...

The United States is home to a diverse array of freshwater and marine fish, shellfish, and other aquatic species. More than 3,000 species of fish inhabit America’s streams, rivers, lakes, reservoirs, marshes, swamps, bays, estuaries, coral reefs, seagrass beds, shallow water banks, deep ocean canyons, and other aquatic habitats. The United States is also home to more than 322 million people, 39% of whom live near the coasts and all depending on the same water that fish call home. In 2012, approximately 25 percent of the nation’s acreage was agricultural and 6 percent was developed. However, these and other consequences of human inhabitation affect much broader areas by altering water flow (hydrology), water quality,...

Partnership - Matanuska-Susitna Basin Salmon Habitat Partnership Montana Creek, near Talkeetna, Alaska in the Matanuska-Susitna Borough has been identified by the State of Alaska as important for the spawning, rearing, or migration of anadromous fish. This system has high quality spawning gravels and provides critical spawning, rearing, and overwintering habitats for Chinook, Coho, Pink, and Chum Salmon as well as resident populations of Rainbow Trout and Arctic Grayling. It receives heavy angling attention during the summer months and is the focus of a variety of ongoing habitat and fish assessment projects, streambank restoration activities, as well as land conservation activities and community asset planning....

Partnership - Fishers and Farmers Partnership The Boone River Watershed is included in the Mississippi River Basin Initiative and is a priority watershed of the Fishers & Farmers Partnership, the Iowa Department of Natural Resources (DNR), and the Nature Conservancy (TNC). The Boone River is a tributary of the Des Moines River in north-central Iowa. Current and past land use practices in the Boone River Watershed have affected both water flows and currents through excessive siltation. As a result, oxbow habitat has been degraded and fragmented and water quality impaired. Oxbows are wetlands, ponds or lakes, often crescent shaped, that form when a stream reach becomes separated from the main stream when sedimentation...

Texas has flown flags for six different nations, which complicates fisheries management in this region. Spain 1519-1685 France 1685-1690 Spain 1690-1821 Mexico 1821-1836 Republic of Texas 1836-1845 United States 1845-1861 Confederate States 1861-1865 United States 1865 to present More land is farmed in Texas than in any other State. Texas has 624 miles (1,024 kilometers) of coastline along the Gulf of Mexico. The Trinity River is 710 miles (1,140 kilometers) long and is the longest river that flows entirely within the State of Texas. Original Federal plans called for building 36 locks and dams from Trinity Bay near Houston to Dallas but only 7 were built. The Brazos River is translated as "The River of the Arms...

Partnership - Matanuska-Susitna Basin Salmon Habitat Partnership Alexander Creek Watershed, a tributary of the Susitna River, was formerly a significant sport fishing area covering hundreds of square miles in the Matanuska-Susitna Borough. In the late 1990s, this system was considered to be a highly productive Chinook and Coho Salmon habitat, and, arguably, the premier Chinook Salmon sport fishing area in the Matanuska-Susitna Valley. Today, however, due to low returns, the Alexander Creek drainage is closed to Chinook Salmon harvest, and Alexander Creek Chinook Salmon are considered a stock of concern by the Alaska Department of Fish and Game. This decline is largely due to the introduction of Northern Pike (...

Tribal communities’ traditions, identities, and economies rely heavily on local natural resources, making tribes especially vulnerable to climate change impacts, including changes in seasonal patterns and the potential loss of culturally and economically important species. The goal of this project was to build tribal capacity in the Pacific Northwest to successfully plan for and adapt to the effects of climate change. The funds associated with this project supported the Affiliated Tribes of Northwest Indians (ATNI) Tribal Leaders Summit on Climate Change held on March 10-11, 2015 in Portland, Oregon. The summit gathered tribal leaders to discuss climate change impacts; share tribal strategies, plans, and policies;...

In order for science to have the most impact on resource management, it needs to directly address the questions that managers and other stakeholders have. Essentially, the ways in which researchers and resource managers collaborate can affect the use of scientific information in decision-making. Previous research has shown that relatively more collaboration between researchers and resource managers (or even the general public) tends to lead to more and more effective use of new scientific information. However, we do not yet have good ways to evaluate these research processes or the outcomes we expect them to produce. This project will assess the key variables necessary for the successful production of usable climate...

This project identifies opportunities to manage flows, connections, and landscapes to increase the resilience of human communities and ecosystems. This research identifies dynamic and adaptive solutions to managing river flows that allow continued provision of valuable infrastructure services such as flood control, hydropower, and water supply, while also supporting thriving river ecosystems - both today and into the future. The goals of the research were to: 1) Evaluate the potential impacts of climate change on hydrologic regimes, 2) Determine the flow regime changes that will be required to provide riverine environmental services and any risk associated with these changes, and 3) Explore management alternatives...

We propose to empirically characterize hydrology/fish-production relationships for different ecological groups of fishes living in the Red River and associated reservoir habitats by: 1. Correlating historic hydrologic data with catch curve residuals, and 2. Annual growth rate estimates of fish collected from the Red River and associated reservoirs. The catch curve residual approach for indexing year class strength has been validated and successfully used to quantify the relationship between reservoir hydrology and YOY recruitment for white crappie and largemouth. The essence of the approach is as follows. Catch curves (a correlation between the natural log of fish abundance and age) are used to measure total instantaneous...

Ecosystem services provided by floodplains include removal of nitrogen, phosphorus, and sediments, and sequestration of carbon. Effectiveness of floodplains in providing these services is dependent on the extent and location of connection between floodplain and river. Tributary loading of sediments, nitrogen and phosphorus to the Upper Mississippi River contribute to the development of river and coastal eutrophication as well as hypoxic conditions in the Gulf of Mexico. Recent research has shown that management of river connectivity of channels to floodplains is an effective mitigation strategy to remove nutrients, sediment, and carbon from river flows. The confluence of the Maquoketa and Mississippi Rivers is a...

The project will use baseline data on pre-restoration measures of baseline hydrology and water quality to evaluate the impacts of large scale wetland and prairire restorations on hydrology and water quality including: recovery of key habitats and functions; abilities of wetlands to buffer variable water flows; ability of groundwater to buffer water flows; groundwater and surface water quality; changes in groundwater movement; rates of denitrification and carbon storage/ transport.
Refinement of Gopher Tortoise Habitat Identification and Related Land Cover Data. The benefits of this project include: 1) much improved gopher tortoise remote habitat identification that could have a strong influence on potential listing status (with the likelihood that significantly more habitat may be identified); 2) better statewide land cover data regarding scrubby flatwoods and potentially refined mesic flatwoods and dry prairie classifications; and 3) potential spin off benefits regarding better habitat identification for related species such as gopher frogs and other xeric adapted species that might be found in on drier flatwoods and dry prairie sites.Continuation of Water Restoration Analyses.

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...

The primary objective of this project is to develop a short synthesis report assessing 11 habitats, using a variety of ecological indicators. The report will be one tool that the South Atlantic LCC can use to inform decision-makers, stakeholders, and the general public about the health of South Atlantic habitats. To achieve this project, six discrete project tasks have been identified and are outlined in the next section.1) Project start-up and pre-workshop preparation: IAN will carefully review the Conservation Blueprint habitats and the indicators used to assess the health of these habitats. We will become familiar with the thresholds and data analysis that the South Atlantic LCC is using for their project. This...

In the western U.S., rising temperatures and pronounced drought conditions pose significant challenges to public land managers. Widespread declines of multiple plant species have already been observed, providing insight into what the future could look like for vegetation in the region as conditions are projected to become warmer and drier. To understand how vulnerable western ecosystems are to drought, managers need to know which climatic and soil conditions cause habitats to change, and at what rate these changes may occur – important topics on which there is little available data. This project seeks to identify the vulnerability of habitats in the western U.S. to drought. Researchers will compare changes in...
