Lake Erie Tributaries: Nutrient and streamflow trend results This data set includes WRTDS nutrient flux trend results and the values of daily streamflow trend results displayed in the Quantile-Kendall plots. For 1995-2015 nutrient trends, the method of generalized flow normalization (FNG) was used which explicitly addresses non-stationary streamflow conditions. For 2005-2015 nutrient trends, the WRTDS trend analyses used the method of stationary flow normalization (FNS) because streamflow nonstationarity is difficult to assess over this shorter duration time frame. The 1995-2015 annual nutrient trends were determined for all five nutrient parameters (TP, SRP, TN, NO23, TKN), and monthly trends were evaluated only for SRP. The 2005-2015 annual nutrient trends were determined... Categories: Data; Tags: Great Lakes, Indiana, Lake Erie, Michigan, Ohio, All tags...

The increased concentrations of N and P are causing eutrophication of the lake, creating hypoxic zones, and contributing to phytoplankton blooms. It is hypothesized that the P loads are a major contributor to harmful algal blooms that occur in the western basin of Lake Erie, particularly in summer. The Maumee River has been identified by the United States Environmental Protection Agency as a priority watershed where action needs to be taken to reduce nutrient loads. This study quantified rates of biogeochemical processes affecting downstream flux of N and P by 1) measuring indices of potential sediment P retention and 2) measuring...

Walleye (Sander vitreus) are a valuable, highly-exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n=926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed...

(2019), utilizing methods for evaluating water-quality and daily-streamflow trends described also in Hirsch and DeCicco (2015 and 2018a) and Hirsch (2018). The trend results and model-input data focus on 10 locations in the Lake Erie watershed that have long-term (20 or more years) water-quality and streamflow monitoring records. The trend results include the years 1987 through 2016 or specified sub-periods during this time frame. The model-input data records spanned the time period 1974 through 2016 although record lengths varied by site, data type, and trend analysis.

To determine how age-0 walleye have responded to changes in prey species and abundance, larval and young of year walleye were collected from western Lake Erie in 2019 and 2014. Larval and young of year fish stomachs were extracted and dissected, with prey contents removed for later identification. All prey contents were identified to the lowest possible taxonomic level using a dissecting microscope and counted, with up to 20 prey items from each taxa per fish measured (0.01 mm) using a digital computer image analysis system. Zooplankton prey items were identified... Categories: Data; Tags: Aquatic Biology, Aquatic invasive species, Diets, Ecology, Fish, All tags...

Most headwater streams of the Maumee River are predominantly agricultural in land use, interspersed with rural communities. Implementation of best management practices on agricultural operations has worked to limit the amount of material that is carried to the stream from cropland. However, several studies have shown streambank erosion to be another source of suspended sediment in these streams. The objective of this work was to map streambank erosion and soft, streambed sediment abundance along stream reaches in a basin that is currently...

We propagated these field-collected samples to carry out a reciprocal-transplant plant-soil feedback experiment with multiple microbial inhibition treatments. Specifically, we investigated how each Phragmites lineage grew in soils pre-conditioned by each lineage and soils that had been pre-sterilized. Plant biomass was the main response variable collected to determine responses to microbial soil conditioning. We also used DNA meta-barcoding to identify...

Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

Although toxic to metazoans, the evolution of microcystin pre-dates the appearance of metazoans, and so MC did not originate as a toxin to potential metazoan grazers. One hypothesized functional role of microcystin is the management and acquisition of metals, several of which form complexes with MC intracellularly. Metals are often used to build enzymes within the cell that allow cyanobacteria to use non-preferred nitrogen (N) and phosphorus (P) sources, such as nitrate, urea and organic P. If trace metals are in low supply, primary producers may become limited because of their inability to access these non-preferred N and P forms....

This basin is monitored in cooperation with the Great Lakes Restoration Initiative (GLRI). During the period July 22-25, 2019 (summer low flow), the thickness and spatial extent of soft, mobile, fine-grained (mainly silt and clay) streambed sediment was inventoried and sampled along 150-meter (m) transects.

The ADCM was deployed on the bottom of River Raisin at approximately 41.899978°N, -83.353548°E and took measurements from August 17-September 13, 2023. These data were collected in cooperation with U.S. Environmental Protection Agency (USEPA), to provide them with data that may help them better understand water velocities caused by river currents, ship traffic, or anything else that could cause the erosion of a 'cap' installed on the river bed that was designed to prevent the dispersion of contaminated soil.

In Lake Erie, the recruitment bottleneck window determining year class strength of Lake Whitefish occurs during the first growing season, suggesting that availability of prey could be controlling year class strength. Therefore, spatial and seasonal larval Lake Whitefish distribution, diet, and environmental zooplankton (potential prey) were collected to evaluate larval Lake Whitefish diets at 31 locations in the western basin during 2017, 2018, and 2021.

Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 42 metals, and particle-size analysis. Fluvial-target samples include both soft, streambed sediment and streamflow-integrated, monthly, suspended-sediment samples for water year 2018.
