Water Quality and Availability is an indicator of the Midwest Landscape Initiative’s (MLI) 2023 Midwest Conservation Blueprint. The Blueprint is a basemap of priority lands and waters for conservation across the Midwest consisting of over 20 social and environmental values representing diverse interests across society. This indicator was chosen as a targetable, important feature of the MLI goals that will be used to track conditions over time and prioritize areas for conservation. Indicators were defined through elicitation and prioritization exercises with federal and state participants. Criteria for the indicators includes 1) actionable, 2) measurable, 3) relevant to multiple groups across the region, and/or 4)...

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...
Researchers have consistently prioritized the need to measure the status and trends of stream and lake temperatures across Alaska landscapes, and to compile those data for predictive modeling. The goal of this project is to develop an open statewide water temperature network with easily understood and readily implemented data standards to support landscape-level assessments. Development of two-tiered data standard will allow data collectors and data managers the flexibility to use their existing agency protocols, yet set standards that are scientifically robust and suitable for landscape-level analysis.

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.
Longleaf pine (Pinus palustris) ecosystems in the southeastern United States have declined substantially from an estimated 92 million acres in the pre-Columbian time period to 4.3 million acres at present, largely due to agricultural conversion, urbanization and replacement by other forest types, notably loblolly pine (Pinus taeda). The open landscape character of longleaf pine ecosystems is characterized by a lower carbon stocking and prairie-like understory dominated by grasses and low woody vegetation . Lower carbon stocking combined with greater drought tolerance in longleaf pine suggest that longleaf pine stands generally consume less water relative to loblolly pine and slash pine dominated stands. The...

Water temperature is one of the most significant factors in the health of stream ecosystems. Temperature plays a critical role in salmonid reproduction and survivorship and is an essential indicator for monitoring the health of Bristol Bay salmon habitats, which support vital subsistence, commercial and sport fisheries. The objectives of this project are to develop an Implementation Strategy for a voluntary participation water temperature monitoring network for Bristol Bay; expand the annual Water Quality/QAPP Recertification training for local monitors to include standardized water temperature monitoring protocols; initiate temperature monitoring in select drainages; and seek long-term funding for a comprehensive...

This scenario planning decision support tool for the Kankakee River basin as a first case study/proof-of concept. Hydrology models, both surface water and groundwater, and ecology of the Kankakee River watershed will be combined to evaluate the effects of habitat restoration on water suppy ecosystem services, agricultural irrigation demands, urbanization, and waterfowl habitat, and sportsman and recreational user interests. Various scenarios for restoration identified with peer input were tested for the watershed. Each scenario results in different individual and aggregate values for ground water recharge, surface water storage, waterfowl habitat, sportsman and recreational use, and agricultural capacity. Some...
Southwest Alaska is one of the fastest warming regions on Earth and its aquatic resources are at distinct risk from changing climate. Previous work has demonstrated that a variety of physical and biological processes are sensitive to changing climate regimes in this region, including those that support wildlife and fisheries that are of substantial importance for subsistence and commercial activities. This collaborative project will result in the compilation of a database of existing stream, river and lake temperatures that is unmatched anywhere else in Alaska in terms of its spatial and their temporal coverage. Analysis of these data will result in refinement of the monitoring plan developed to characterize thermal...

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.
Streams, rivers, and lakes of the Kodiak Archipelago, Alaska, provide essential spawning and rearing habitat for millions of Pacific salmon collectively regarded as a foundation of the regional ecosystem and economy. Climate projections for the archipelago indicate probable increases in annual and seasonal air temperature over the next 85 years. Corresponding increases in the temperature of freshwaters also are expected, which may adversely influence the biology of salmon, the quality of salmon habitat, and the availability of salmon to support the ecosystem and economy. It is essential that salmon managers be provided with relevant and reliable information on expected changes in thermal regimes and their influence...

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...
