REPORT PROJECT BACKGROUND: Golden alga (Prymnesium parvum) is a harmful algal species that is primarily found in marine ecosystems but is also present and invasive in brackish inland waters. The first documented bloom of golden alga in the United States occurred in the Pecos River in 1985. This species has since invaded other water bodies in the Pecos River basin (e.g. sinkhole habitats, reservoirs) and has been reported in at least 23 U.S. states. Toxins produced by golden alga can be lethal to fishes, bivalves, crayfish, and gilled amphibians. The ecological and economical impacts of golden alga blooms have been severe. Recent research suggests that the frequency and severity of golden alga blooms will increase...

Wetland hydroperiod, the length of time water is available in wetlands, is particularly sensitive to changes in precipitation, temperature and timing due to climate variation. Truncated hydroperiod has major implications for wetland-dependent species (e.g., waterfowl) and human water allocation. Researchers aim to link hydroperiod to current climatic variation and use this relationship to predict wetland hydroperiod across the moisture gradient from sage steppe to grasslands.

Man-made water sources have been used as a management tool for wildlife, especially in arid regions, but the value of these water sources for wildlife populations is not well understood. In particular, the value of water as a conservation tool for Lesser Prairie-Chickens (Tympanuchus pallidicinctus) is unknown. However, this is a relevant issue due to a heightened conservation concern for the species and its occupancy of an arid landscape anticipated to experience warmer, drier springs and winters. We assessed if Lesser Prairie-Chickens would use commercially available wildlife water guzzlers and if there was any apparent selection between two design types. We confirmed that Lesser Prairie-Chickens would use bird...

The distribution and abundance of fishes across the Alaska Arctic is not well understood. Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.
Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure...

The importance of riparian ecosystems in semiarid and arid regions has generated interest in understanding processes that drive the distribution and abundance of dominant riparian plants. Changes in streamflow patterns downstream of dams have profoundly affected riparian vegetation composition and structure. For example, in the southwestern United States, flow regulation has contributed to the replacement of many riparian forests historically dominated by the native Populus fremontii (Fremont Cottonwood) and Salix gooddingii (Goodding’s Willow) by the exotic species Tamarix spp. (Salt Cedar). The proposed project will help guide reservoir release decision making to enhance downstream recruitment of native cottonwood...

Executive Summary: Evolution of policies that guide operation of individual reservoir systems begins with a relative flurry of activity associated with building of dams. Over perhaps a ten year period, operations are proposed in anticipation of construction, implemented when a dam is complete, and then modified as the effects, capabilities, and limitations of the project become better understood. After these initial adjustments, the policy process slowly begins to simmer. Operational changes are the driven by short-term influences that are largely episodic (e.g. droughts and floods) and long-term influences (e.g. social and economic factors) that affect operations more gradually.

The impact of agricultural drainage and resulting non-point source nutrient export on water quality is a growing concern across the entire Prairie Pothole Region. In Canada, the three Prairie Provinces (Alberta, Manitoba, and Saskatchewan) are currently revising and reviewing surface water management strategies and have recognized the need for wetland restoration and conservation to help maintain and restore water quality, and sustain watershed health. However, unlike the US portion of the PPR, there is no complete wetland inventory for the Canadian portion of the PPR. As a result it is not currently possible to target wetland conservation and restoration efforts to maximize water quality benefits. This project...
Our approach will include sampling a wide range of habitats and environmental conditions throughout the middle and lower Pecos River basin, across an 18 month time-span to account for seasonal and phenological events. We will utilize a suite of univariate and multivariate statistical techniques to relate occurrence and density of golden alga to environmental factors and other co-occurring organisms. The proposed research will benefit managers of the Pecos River, of its associated reservoirs and unique habitats (sinkholes on the Bottomless Lakes State Park and Bitter Lakes National Wildlife Refuge), and of its resident aquatic biota by identifying specific water quality attributes that promote golden alga bloom development...

There is currently have a very poor understanding of how climate change will affect food web structure and mercury accumulation in lakes on the Arctic Coastal Plain of Alaska. In this study, researchers are addressing this knowledge gap by adopting a space-for-time approach. Fish and food web ecology, and mercury accumulation patterns, are being investigated in several lakes that represent a gradient in temperature/ice phenology of up to two ice-free weeks and 10°C. They are also comparing food web structure and rates of mercury biomagnification among the lakes, and relating these to several climate variables. Finally, they are relating past trends in mercury accumulation in lake sediments to indices of lake productivity...

The National Stream Internet (NSI) project was funded by the Landscape Conservation Cooperative program and led by researchers from USFS, CSIRO, NOAA, and USGS. The project developed a national analytical infrastructure for stream data that can be applied consistently anywhere in the country to develop new information at low cost. To create that infrastructure, the NSI project developed compatibility among key digital stream geospatial data and analysis tools. Those included the EPA/USGS NHD-Plus v.2 stream hydrography layer, sets of stream reach descriptors, and tools for implementing spatial statistical network models. The NSI enables consistent application of sophisticated analysis tools to many types of stream...

Researchers with U.S. Geological Survey Water Science Centers in Iowa, Kansas and Massachusetts collaborated to conduct a comprehensive literature search of both published and ongoing research (2000-present) that sheds light on the interactions between climate change, agriculture and water quality across the combined geographies of the Eastern Tallgrass Prairie and Big Rivers LCC and neighboring Upper Midwest and Great Lakes LCC. Project investigators compiled the information in a resource library by geographic location, providing an organized structure for future examination of all research related to interactions between climate change, agriculture and water quality in these two regions.

LCC funding for this project helped maintain a network of hydrology monitoring sites in a representative watershed of the Arctic Coastal Plain. The work was conducted within the context of climate change and impending oil and gas activities in the region, the latter of which is the impetus for focusing on the Fish Creek watershed. The project included two monitoring components:1) Beaded Stream & Lake Hydrology Monitoring (dominant habitat type within the watershed): in 6 stream/lake complex watersheds (Redworm, Hannahbear, Blackfish, Crea, Oil, and Bills creeks), continuous water level and temperature (in lakes, streams, and confluences), discrete discharge measurements, and continuous water quality (specific conductivity,...

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

Groundwater pumping for irrigated agriculture has depleted regional aquifers that sustain habitat for native fishes in the western Great Plains of North America. Depleted surface stream flow is implicated in the decline of 69% of endemic Great Plains fishes, including conservation priority species such as the Arkansas River shiner Notropis girardi. Species declines are likely to continue as water demands increase. Knowledge of spatial patterns of hydrologic connectivity and rates and magnitude of fragmentation through time will help prioritize areas for native fish conservation. We propose to use groundwater-surface water models to document and map the spatiotemporal distribution of flowing and intermittent stream...

Water temperature plays a critical role in the health of pre-smolt salmon life stages, and changes in water temperature may be a strong driving factor on growth and survival of juvenile Chinook salmon. Climate is expected to warm substantially in the coming decades in western Alaska, potentially affecting juvenile salmon condition in freshwater habitats. This project investigated the feasibility of using existing data to assess the variability in size-at-age and annual growth for juvenile Chinook salmon across the western Alaska landscape and to estimate the relationship between juvenile Chinook size-at-age or annual growth and spatial or temporal stream temperature gradients. The project showed adequate data exists...
