This dataset contains all data used in this study, including site ID, latitude, longitude, watershed land cover, water chemistry, and carbon and nitrogen stable isotope ratios of periphyton, invertebrate functional feeding groups, and five most frequently observed invertebrate families. Also included is a list of all invertebrates collected in this study along with their functional feeding group and stable isotope ratios. This dataset is associated with the following publication: Smucker, N., A. Kuhn, C. Cruz-Quinones, J. Serbst, and J. Lake. Stable isotopes of algae and macroinvertebrates in streams respond to watershed urbanization, inform management goals, and indicate food web relationships. ECOLOGICAL INDICATORS. Elsevier Science Ltd, New York, NY, USA, 90: 295-304, (2018).

This release includes data used to evaluate the structure and function of the Ross Lake and Diablo Lake food webs. This includes data on zooplankton density and production (zooplankton_density.csv and daphnia_region_production_biomass.csv), lake volume estimates used to expand zooplankton density and production data (lake_volume_estimates.csv), fish sampling (FishSampleEvents.csv), fish biological information including diets, age, and stable isotope analysis (FishFullData_formatted.csv, FishPreyLength.csv), scale back-calculations (salmonid_back_calc.csv, rss_back_calc.csv), fish energy density (calorimetry_processed.csv), stable isotope data for invertebrate end members (si_inverts.csv), and hydroacoustic sampling (ross_ha_densities.csv, diablo_ha_densities.csv). Fish and zooplankton sampling and stable isotope analysis were conducted by the USGS in 2019-2021, and hydroacoustics surveys were conducted in 2021. These data were also combined with fish data (species, size, age) from the National Park Service collected in 2005-2017 to evaluate fish size and age structure across a larger period of time. The bioenergetics model and information on running the model including inputs and outputs from our simulations and a user guide can be found the in FB4.zip folder. Please refer to the associated publications for additional details about data collection and processing.

Rocky riffles in rivers support a complex community of algae, bacteria, fungi and detritus often held together by a polysaccharide matrix. This biofilm provides food for invertebrates, some fish, platypus, rakali and turtles. Biofilms are scoured naturally by high flows. River regulation alters the timing, duration and frequency of biofilm scouring. Environmental flows downstream of dams, including translucent and transparent releases are designed to restore some of the variability of flow and allow scouring to reset early-stage biofilm, which is more palatable for aquatic animals. IMEF biofilm and invertebrate studies were performed in the Hunter and Murrumbidgee Rivers, testing the hypothesis (IMEF Hypothesis 4) that restoring some freshes and high flows would induce scouring of silt and biofilms and improved habitat quality for some invertebrate scrapers and their predators. Sites located on the Murrumbidgee River downstream of Burrinjuck Dam, received periodic environmental releases, between April and October, as well as irrigation flows and uncontrolled spills. Riffle rock biofilms, aquatic invertebrate metrics and water quality were compared with reference sites on the unregulated Goobarragandra and Goodradigbee rivers. Control sites were chosen on the Tumut River, which is regulated by Blowering Dam but unlike the Murrumbidgee River did not receive variable environmental releases.

The data are species counts by location, as well as other environmental variables for each stream location sampled. This dataset is associated with the following publication: Stamp, J., A. Moore, S. Fiske, J. Gerritsen, B. Bierwagen, and A. Hamilton. Effects of Extreme High Flow Events on Macroinvertebrate Communities in Vermont Streams. River Research and Applications. John Wiley & Sons Incorporated, New York, NY, USA, 36(9): 1891-1902, (2020).

The dataset contains information on aquatic macroinvertebrates that has been collected under the Monitoring River Health Project (1994-2000), the Sustainable Rivers Audit (2002-2012) and the Monitoring Evaluating and Reporting (MER) program (2006 ongoing) across the whole of NSW. The data were collected using the AUSRIVAS protocols (available at http://ausrivas.canberra.edu.au/Bioassessment/Macroinvertebrates/) which includes in situ water quality measurements, site habitat assessment and macroinvertebrate data. The dataset has a latitude and longitude and site access information for every sample site.

This data set includes water quality data and microbial community abundance tables for periphyton samples from this project. The data set also includes extensive R markdown code used to process the data and generate the results included in the report. This dataset is associated with the following publication: Hagy, J., R.
