2024 Ohio River Basin Alliance Summit

Healthy Waters, Healthy Communities: From Headwaters to Mainstem"


The 2024 ORBA Summit, held at the esteemed University of Pittsburgh from October 30 to November 1, was a landmark event that united a diverse array of voices from community organizations, academic institutions, government agencies, and non-profits, all driven by a common purpose: the health and restoration of the Ohio River Basin. With an impressive turnout of 276 registrants from 11 different states plus Washington, D.C., this three-day summit was a vibrant hub of knowledge and collaboration, featuring 40 dynamic sessions led by 76 presenters fostering discussions and collaborations aimed at enhancing the health and sustainability of the Ohio River Basin. Attendees had the opportunity to engage in five field trips, participate in networking sessions, and experience a thought-provoking movie screening, all while connecting with representatives from influential organizations such as the U.S. Army Corps of Engineers, U.S. Geological Survey (USGS), and RiverLife. The breadth of participation—ranging from Pittsburgh Water and Sewer to American Rivers—illustrates the deep commitment to environmental stewardship and community engagement.

ORSANCO Technical Programs Updates

National Rivers and Streams Assessment (NRSA)



The Biological crew completed their work with NRSA in early October. In total, 92 sites across 4 states (Illinois, Indiana, Kentucky, and Ohio) were completed. These streams ranged in size and included electrofishing by boat, bass buggy, and electrofishing backpacks.


NRSA is an EPA collaborative survey that provides information on the ecological condition of the nation's rivers and streams and the key stressors that affect them, both on a national and an ecoregional scale. These surveys are based on chemical and biological data collected and analyzed using standardized field and laboratory methods.

Ohio River Pool Surveys


In addition to NRSA work this year, Montgomery and Newburgh pools were sampled assessing water quality, habitat, aquatic vegetation, as well as macroinvertebrate and fish populations. This year, the standard operating procedure (SOP) for collecting macroinvertebrates was modified. Changing from years prior, two Hester Dendy (HD) samplers were set in order to increase the likelihood of retrieval in the Newburgh pool. It is not uncommon for HDs to be moved, lost, or washed ashore, making their data unusable. In the past, only one HD per site was set and a multi-habitat kick sample was also collected to be used in the event that an HD was unable to be retrieved. However, since multi-habitat data must meet demanding criteria in order to be applied to the ORMIn index, it was decided that efforts were best placed on ensuring successful HD retrieval.

Benthic Algae Project


While there has been a recent focus on harmful algal blooms, benthic algae communities have been largely ignored. Beginning in August, ORSANCO staff have been assisting USEPA ORD researchers to help develop a methodology for sampling benthic harmful cyanobacteria blooms (HCBs) and their toxins to better understand the role of benthic blooms in cyanotoxin production and establish tools for identification and quantification of HCBs.


This project includes periodic collection of grab water samples coinciding with ORSANCO's routine fecal indicator bacteria monitoring to analyze for nutrient species and genes coding for cyanotoxins using quantitative polymerase chain reaction (qPCR), a laboratory technique that amplifies and measures DNA in real time. ORSANCO also hosted USEPA ORD researchers to sample 15 sites in the Markland pool by boat, collecting benthic sediment samples via ponar grab sampler, surface and depth samples, and general water quality parameters. Other sampling efforts are being conducted in Virginia, Utah, California, and Washington to help develop this methodology.

Harmful Algal Blooms (HABs)


This summer, ORSANCO investigated two Aulacoseira blooms after water utilities reported reduction in their filter run times. The first of these blooms occurred in early June and seemed to be localized to Maysville, KY (Ohio River Mile, ORM 408) and lasted about one week. The second of these Aulacoseira blooms was first reported in Louisville, and was seen upstream as far as Meldahl Lock and Dam. It persisted until late July, peaking the week of July 9th.


Louisville Water reported a Microcystis bloom on the Kentucky River near the end of July with toxin levels at 4.69ug/L. When Kentucky EEC went to investigate, there were no signs of a bloom. On August 1st, the bloom reappeared in Louisville near ORM 502. Algal toxins exceeded the standard and Kentucky EEC issued an advisory. ORSANCO assisted Kentucky DEP and Indiana DEM with algal toxin sampling. Microcystis toxins were only detected in five of the 27 samples collected by ORSANCO, and levels in all samples were below the recreational standard of 8.0 ug/L. After ten days of samples being below the recreational advisory threshold, the advisory was lifted on August 22nd.
