a) fish data were collected 2018, 2020, and 2022.
Site IB-01: IB-01 received a BIBI score of 2.14 (Poor) in 2023, the second consecutive year with a score below 3.00 after four years of scoring 3.00 or higher. The cumulative average BIBI score for 2017-2023 is 2.92 (Poor) while the three-year running average is 2.81 (Poor). True flies have been the dominant organism in samples over the past four years.
IB-01 Summary of Insects Collected by Sample Year:
Site IB-01: The site was fished in 2018, 2020, and 2022, receiving a “Poor” or “Very Poor“ rating each time. Bluegill (Lepomis macrochirus) made up over 50 percent of the 2022 sample, and is the only species to be found in all three years of sampling. Largemouth bass (Micropterus salmoides), bluespotted sunfish (Enneacanthus gloriosus), brown bullhead (Ameiurus nebulous), and eastern mudminnow (Umbra pygmaea) have also been found here. The number of individual fish found at this site is low, with 30 (in the 2022 sample) being the highest count to date.
IB-01 Summary of Insects Collected by Sample Year:
Site IB-01: The 2023 RBP score of 103 (Partially Supporting) is consistent with RBP scores dating back to 2018. The cumulative average and the three-year running average scores are both in the Partially Supporting category at 111 and 104, respectively.
Site IB-01: A geomorphological assessment was performed here in 2010, as part of a separate project and before yearly assessments began in 2017. Between 2010 and 2022 the channel incised by nearly 4 feet, indicating increased peak flows and little interaction between the stream and the surrounding floodplain. A collapse of the right bank between the 2022 and 2023 measurements resulted in a 3-foot retreat of the right bank and the deposition of 2 feet of sediment on the channel bottom.
