Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent, frequency, duration, and timing of inundation. These metrics can be delivered to managers efficiently through cloud-based interactive maps. To calculate these metrics, we interpolated an existing one-dimensional HEC-RAS hydraulic model for the Lower Missouri River, which simulated water surface elevations at cross sections spaced (<1...
Floodplains pose challenges to managers of conservation lands because of constantly changing interactions with their rivers. Although scientific knowledge and understanding of the dynamics and drivers of river-floodplain systems can provide guidance to floodplain managers, the scientific process often occurs in isolation from management. Further, communication barriers between scientists and managers can be obstacles to appropriate application of scientific knowledge. With the coproduction of science in mind, our objectives were the following: (1) to document management priorities of floodplain conservation lands, and (2) identify science needs required to better manage the identified management priorities under...

Stream fish are in peril from a changing climate, particularly for species with restricted distributions or populations on the southern edge of their range. For these fish, the opportunity to escape warming temperatures is limited by the network of stream channels accessible to them. To deal with temperatures beyond their physical capacity, fishes must move, adapt, or die. However, little is known for many of these species about their preferred temperatures, critical temperature limits, or capacity to adapt to or tolerate increasing temperatures. Researchers will measure the preferred temperatures and tolerance of two stream fish that are vulnerable to climate change: the Ozark Shiner and the Blacknose Shiner. The...

This database contains physical and biological data for the Lower Colorado River Basin. The metrics include information on geology, hydrology, landcover, stewardship, topography, soil types and characteristics, stream characteristics, connectivity, and watershed position (information on where a stream segment or catchment is located in relationship to other segments or catchments; e.g. distance from a catchment to the mouth of the Colorado River, Shreve Link). In addition, there is a table with predicted probability of species occurrence for the connected stream segments and tables with the data used in those models. The species distribution models were completed for 18 native fish species and 21 non-native fish...

Climate change is reshaping the abundance and distribution of sport fishes across the U.S., creating novel challenges for socially and economically important recreational fisheries. Existing fish and recreational fisheries data sets are invaluable given their broad geographic footprint and long-term data, but integration across datasets to inform management has been limited, leading to obstacles in collaborative research and management efforts. Agencies that manage recreational fisheries also conduct angler surveys to assess how anglers may affect fish populations, however they are rarely integrated with other datasets or with consideration of how climate change may affect the fish available to anglers. In this...

Recent extreme floods on the Mississippi and Missouri Rivers have motivated decision-makers and resource managers to expaned floodplain conservation lands. Within Missouri, there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly climatic conditions change. These lands have the potential to provide valuable ecosystem services, like wildlife habitat, nutrient processing, carbon sequestration, and flood-water storage, that produce economic values in terms of recreational spending, improved water quality, and decreased flood hazards. However, floodplain managers may need tools to help them understand changing...

The Large River Monitoring Forum compiled fish assemblage data for five large rivers in the U.S. as a part of a coordinated effort to compare and contract river monitoring efforts in large river systems. Fish community data from five monitoring programs were integrated to create the standardized dataset. Authors: Timothy D. Counihan1, Ian R.

Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the region’s streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results of a current condition assessment of stream habitats based on fish response to human land use, water quality impairment,...

Stocking, or raising fish in hatcheries and releasing them into a body of water, is routinely used to supplement or maintain fisheries when natural populations are low or nonexistent. Demand for stocking cool and coldwater fish species that support important fisheries will likely increase as a result of climate change, but fish available for stocking are a limited resource. Consequently, climate change will likely affect supply-and-demand tradeoffs associated with stocking fish in the future, where demand for fish is likely to exceed supply. Researchers will examine supply-and-demand tradeoffs using walleye, which represent an ideal species for this assessment because they are a native coolwater species supporting...
