This page contains model inputs and results from 390 Fluvial Egg Drift Simulator (FluEgg) (version 4.1.1) simulations of invasive carp eggs and larvae in the Maumee River, Ohio, under steady flow conditions. FluEgg models the drift and dispersion of eggs and larvae in fluvial environments. The eggs develop, changing in size and density, and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage. FluEgg requires the user to provide hydraulic data to drive the drift model. The hydraulic inputs for these FluEgg simulations were generated using a one-dimensional steady hydraulic model of the Maumee River (see the other child items of this data release for more information about the hydraulic model) for 10 steady flow conditions: 500 cubic feet per second (cfs), 1,000 cfs, 5,000 cfs, 10,000 cfs, 15,000 cfs, 20,000 cfs, 25,000 cfs, 35,000 cfs, 65,000 cfs, and 100,000 cfs at the U.S. Geological Survey (USGS) streamgage 04192500 Maumee River near Defiance, Ohio. The upstream end of the model domain (0.0 river kilometers) is located 280 meters downstream from Independence Dam near Defiance, Ohio, and the downstream end of the model domain is the mouth of the Maumee River at Lake Erie near the National Oceanic and Atmospheric Administration (NOAA) tidal gage 9063085 (95.6 river kilometers). In FluEgg, the hydraulic conditions at the downstream end of the model domain extend infinitely downstream to allow eggs and larvae to drift beyond the model domain. Therefore, any drift distances greater than 95.6 kilometers should be excluded from further analysis of these data. FluEgg simulations were run for all combinations of the 10 steady flow conditions, six water temperatures, and three spawning locations. For 2 of the 10 flows (10,000 and 20,000 cfs), FluEgg simulations were run for a single invasive carp species (grass carp). For the remaining eight flows, simulations were run for three invasive carp species (bighead, silver, and grass carp). The six water temperatures were 18, 20, 22, 24, 26, and 28 degrees Celsius. The streamwise coordinates of the three spawning locations were 0.0 (280 meters downstream from Independence Dam; "loc01"), 45.0 (near Grand Rapids/Providence Dams; "loc04"), and 72.5 river kilometers downstream from the upstream end of the FluEgg model domain ("loc10"). Each simulation included 5,000 invasive carp eggs, which were assumed to have been spawned at the water surface and at the midpoint of the channel. This page includes: MaumeeRiver_steady_fluegg_sim_list.csv: comma-separated values (csv) file listing the simulation parameters used for 390 steady FluEgg simulations. MaumeeRiver_steady_fluegg_inputs.zip: zipped folder containing csv files used as the hydraulic inputs for FluEgg simulations. MaumeeRiver_centerline.KML: KML file of the Maumee River centerline that represents the model domain. 78 zipped folders containing FluEgg results files. The folder names follow the convention maumee_LOC_FLOW_SPECIES_5000eggs.zip, where LOC refers to the spawning location (loc01, loc04, or loc10), FLOW refers to the discharge at USGS streamgage 04192500 - Maumee River near Defiance, Ohio, in cfs (500cfs, 1000cfs, 5000cfs, 10000cfs, 15000cfs, 20000cfs, 25000cfs, 35000cfs, 65000cfs, or 100000cfs), SPECIES refers to the invasive carp species (bighead carp, grass carp, or silver carp), and 5000eggs refers to the use of 5000 invasive carp eggs in the simulations.

This page contains results from 304 Fluvial Egg Drift Simulator (FluEgg; version 4.1.1) simulations of invasive carp eggs and larvae in the Maumee River, Ohio, under unsteady flow conditions. FluEgg models the drift and dispersion of eggs and larvae in fluvial environments. The eggs develop, changing in size and density, and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage or when the set duration of the simulation is exceeded (whichever comes first). FluEgg requires the user to provide hydraulic data to drive the drift model. The hydraulic inputs for these FluEgg simulations were generated using a one-dimensional unsteady hydraulic model of the Maumee River (see the other child items of this data release for more information about the hydraulic model) for four unsteady flow periods in which grass carp eggs or larvae were collected on the Maumee River: July 11-14, 2017, June 11-14, 2018, June 22-27, 2018, and May 28-30, 2019. The upstream end of the model domain (0.0 river kilometers) is located 280 meters downstream from Independence Dam near Defiance, Ohio, and the downstream end of the model domain is the mouth of the Maumee River at Lake Erie near NOAA tidal gage 9063085 (95.6 river kilometers). In FluEgg, the hydraulic conditions at the downstream end of the model domain extend infinitely downstream to allow eggs and larvae to drift beyond the model domain. Therefore, any drift distances greater than 95.6 kilometers should be excluded from further analysis of these data. FluEgg simulations were first run in reverse using the reverse time particle tracking algorithm (RTPT) in FluEgg using the time, location, and developmental stage of 73 captured grass carp eggs and larvae as input. Accounting for replicates, a total of 28 FluEgg simulations were run in reverse for a single invasive carp species (grass carp). Because RTPT simulations result in distributions of potential spawning areas, a series of 276 iterative forward FluEgg simulations were run to further refine the likely grass carp spawning area for the 28 groups of eggs/larvae. Each simulation included 10,000 grass carp eggs, which were assumed to have been spawned at the water surface and at the midpoint of the channel.

Data collection, along with hydraulic and fluvial egg transport modeling, were completed along a 70.9-mile reach of the Ohio River between Markland Locks and Dam and McAlpine Locks and Dam. Data were collected during two surveys: October 27–November 4, 2016, and June 26–29, 2017. Water-quality data collected in this reach included surface measurements and vertical profiles of water temperature, specific conductance, pH, dissolved oxygen, turbidity, relative chlorophyll, and relative phycocyanin. Streamflow and velocity data were collected simultaneously with the water-quality data at cross sections and along longitudinal lines (corresponding to the water-quality surface measurements) and at selected stationary locations (corresponding to the water-quality vertical profiles). The data were collected to understand variability of flow and water-quality conditions relative to simulated reaches of the Ohio River and to aid in identifying parts of the reach that may provide conditions favorable to spawning and recruitment habitat for bighead carp (Hypophthalmichthys nobilis). A copy of an existing hydraulic model of the Ohio River was obtained from the National Weather Service and used to simulate hydraulic conditions for four different streamflows. Streamflows used for the simulations were selected to represent a range of conditions from a high-streamflow event to a seasonal dry-weather event. Outputs from the hydraulic model were used as input to the Fluvial Egg Drift Simulator (FluEgg) along with a range of five water temperatures observed in water-quality data and four potential spawning locations to simulate the extents and quantile positions of developing bighead carp, from egg hatching to the gas bladder inflation stage, under each scenario. A total of 80 simulations were run. Results from the FluEgg scenarios (which include only the hydraulic influences on survival that result from settling, irrespective of mortality from other physical factors such as excess turbulence, or biological factors such as fertilization failure, predation or starvation) indicate that the majority of the eggs will hatch, about half will die, and a quarter of the surviving larvae will reach the gas bladder inflation stage within the modeled reach. The overall average percentage of embryos surviving to the gas bladder inflation stage was 13.1 percent. Individual simulations have embryo survival percentages as high as 49.1 percent. The highest embryo survival percentages occurred for eggs spawned at a streamflow of 38,100 cubic feet per second and water temperatures of 24°C to 30°C. Conversely, embryo survival percentages were lowest for the lowest and highest streamflows regardless of water temperature or spawn location. Under low water temperature, high-streamflow conditions, some of the eggs did not hatch nor did the larvae reach the gas bladder inflation stage until passing beyond the downstream model domain. While the final quantile positions of the eggs and larvae beyond the downstream model domain are unknown, the outcomes still provide useful information.

The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013, Domanski, 2020). Hydraulic inputs for a series of FluEgg simulations were generated using a one-dimensional steady Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model for the Illinois River between Marseilles Lock and Dam and the Mississippi River confluence near Grafton, Illinois (HEC-RAS, 2019). The HEC-RAS model was developed by combining four individual HEC-RAS models obtained from the U.S. Army Corps of Engineers Rock Island District (U.S. Army Corps of Engineers Rock Island District, 2003). The model was run for the following ten flow profiles: half the annual mean flow, annual mean flow, annual mean flood, 2-year peak flow, 5-year peak flow, 10-year peak flow, 25-year peak flow, 50-year peak flow, 100-year peak flow, and 500-year peak flow. The flow rates for each of the profiles were obtained for the following U.S. Geological survey (USGS) streamgaging stations from USGS StreamStats: 5543500 Illinois River at Marseilles, Illinois, 5558300 Illinois River at Henry, Illinois, 5560000 Illinois River at Peoria, Illinois, 5568500 Illinois River at Kingston Mines, Illinois, 5570500 Illinois River near Havana, Illinois, 5585500 Illinois River at Meredosia, Illinois, 5586100 Illinois River at Valley City, Illinois (Soong and others, 2004; Granato and others, 2017).

The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013, Domanski, 2020). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions. The data release also contains the hydraulic inputs used in the FluEgg simulations and a KML file of the centerline that represents the model domain. FluEgg simulations were run for all combinations of four spawning locations, six water temperatures, and ten steady flow conditions. Each simulation included 5,000 bighead carp eggs, which develop and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage. The four spawning locations were just downstream of the lock and dam structures at Marseilles, Starved Rock, Peoria, and LaGrange. For each of these spawning locations, the eggs were assumed to have been spawned at the water surface and at the midpoint of the channel. The six water temperatures were 18, 20, 22, 24, 26, and 28 degrees Celsius. The ten steady flow conditions ranged from half the annual mean flow to the 500-year peak flow and are discussed in more detail below. Note that in the streamwise coordinate system used by FluEgg, the streamwise coordinate of the Mississippi River confluence is 396,639 meters. Any drift distances greater than this value should be excluded from any further analysis of this data. The hydraulic inputs for the FluEgg simulations were generated using a one-dimensional steady Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model for the Illinois River between Marseilles Lock and Dam and the Mississippi River confluence near Grafton, Illinois (HEC-RAS, 2019).
