Summary statistics and open-river days for LD 14-19 in the upper Mississippi River from 2017–2019

Statistics include temperature, hydraulic head, average maximum hydraulic head when dam is at open-river conditions, and open river days provided by the U.S. Army Corps of Engineers (USACE), which were recorded at each respective dam.

Summary residency event (RE) duration for bigheaded carp and paddlefish in the downstream lock approach at Lock and Dam 15 from 2017–2019

The number of residency events (n) and the percentage of RE of each species is separated by season. The residency duration for both species is broken down by number and percentage of RE: ≤ 20 min, > 20 min to ≤ 60 min, > 60 min to ≤ 360 min, and > 360 min.

Confidence model set for residence events generalized linear mixed-effects models

Respective Akaike’s information criterion (AIC), Δ AIC, and Akaike’s weights (wi) values, for bigheaded carp and paddlefish in the downstream lock approach at Lock and Dam 15 from 2017–2019 are included for the model set. ID is a unique tag number associated with each individual. Definitions of each parameter are located in Table 1.

Seasonal bigheaded carp and paddlefish presence events in the downstream lock approach at LD 15 in the upper Mississippi River from 2017–2019

N represents the number of unique individuals that were present in the downstream lock approach per year.

Confidence set for presence events generalized linear models

Akaike’s information criterion (AIC), Δ AIC, and Akaike’s weights (wi), and area under the receiver operating characteristic curve (AUC) for the confidence set of presence events generalized linear models for bigheaded carp and paddlefish in the downstream lock approach at LD 15 from 2017–2019. AUC.test is the performance of the top model when tested with a 20% subset of original data. Cohen’s kappa (κ) is the accuracy of the prediction to the actual occurrence (<0.00 =poor agreement, 0.00–0.20 = slight agreement, 0.21–0.40 = fair agreement, 0.41–0.60 = moderate agreement, 0.61–0.80 = substantial agreement; Landis and Koch 1977). Definitions of each parameter are located in Table 1.

Range testing results at Lock and Dam 15 in April 2019

The orange dots depict the location of a test tag at the time of detection on a receiver. The average detection percentages were calculated for each zone, where the upstream lock approach had two receivers, the lock chamber had two receivers, and the downstream lock approach included 11 receivers.
