Attending conferences is an opportunity for researchers to stay connected with others in their field, cultivate scientific ideas, and foster collaborations for current or future work. While national and international conferences can help promote research visibility for promotion, local events offer the chance to connect with stakeholders throughout the region and coordinate statewide efforts. Local networks can be key players in advancing research and is an important part of making the work done at the Ohio Water Resources Center (Ohio WRC) successful.
The Water Management Association of Ohio (WMAO) is a great way to connect locally. WMAO is dedicated to supporting the water resources of Ohio for all beneficial purposes and serves to represent the voice of water professionals in the determination of our research priorities. The Ohio WRC has a long-lasting partnership with WMAO, co-coordinating Luncheons with WMAO and assisting with the annual WMAO Conference. We encourage our funded researchers to take advantage of this valuable opportunity to interact with diverse stakeholders throughout the state.

What role does nutrient cycling by zooplankton play in supporting HAB production in western Lake Erie? | |
Dr. Jim Hood from The Ohio State University completed an Ohio Water Resources Center funded project via the 104(b) USGS program. Harmful algal blooms (HABs) have increased in severity in western Lake Erie, resulting in serious public health and economic consequences. Though spring P-loading from the Maumee River strongly predicts the summer algal bloom severity, it is not clear how the P is stored and cycled prior to and during bloom formation. The project aimed to determine the relative importance of zooplankton-mediated nitrogen (N) and phosphorus (P) recycling on harmful algal bloom (HAB) development, timing, and magnitude in the western basin of Lake Erie, identify the physicochemical and biological controls of zooplankton nutrient recycling rates and ratios, and understand zooplankton feeding on HABs and other phytoplankton groups.
Dr. Hood’s team completed measurements of zooplankton nutrient recycling (ZNR) and grazing on nine sampling events by quantifying N and P excretion rates by micro- and mesozooplankton regularly at one site in western Lake Erie near the Maumee River mouth. Preliminary results indicated that during cyanobacteria blooms, mesozooplankton grazed primarily on cyanobacteria, but also diatoms or cryptophytes. In contrast, microzooplankton did not have measurable grazing rates for any phytoplankton group during August and grazed only on green algae during September. Preliminary results also indicated measurable individual zooplankton P excretion on four of nine dates for total zooplankton excretion and on two of five dates for microzooplankton excretion. The team is working on analyzing the microzooplankton community samples, which will allow them to address ZNR rates and ratios to evaluate the relative importance of ZNR.

New USGS Educational Tool Better Illustrates the Role Humans Play in Water Availability | |
The water cycle describes where water is stored on Earth and how it is circulated between the earth’s oceans, atmosphere, and land. Historically, the water cycle has depicted only the natural aspects of the cycle. However, the U.S. Geological Survey (USGS) has collected extensive amounts of water data in recent decades that has changed the perspective of the water cycle by demonstrating how human and natural components are interconnected. USGS experts consulted with more than 100 educators and more than 30 hydrologic experts to develop a new diagram that takes this into consideration and shows the bigger picture of water availability.
Understanding how anthropogenic practices influence the water cycle is critical for working toward the sustainable use of water. This new diagram replaces one used by educators and students internationally since 2000 and sets a new standard for how we visualize and communicate the water cycle.

Ohio EPA DDAWG: Interested Party Review 'Amend' Rulemaking Governing Consumer Confidence Reports
The Ohio EPA Division of Drinking and Ground Waters (DDAGW) is soliciting comments on rules within OAC 3745-96 of the Ohio Administrative Code. DDAGW has reviewed these rules to satisfy the five-year rule review requirements of section 106.03 and 106.031 of the Ohio Revised Code. These rules and associated documents are available here. Comments can be submitted by email to ddagw_rulecomments@epa.ohio.gov. Comments should be received at the above address by the close of business, November 10th, 2022.
Ohio EPA DSW: Draft 2018-2019 Biological and Habitat Studies of the Rivers and Streams in Section 319(h) and GLRI Project Areas in Ohio
In 2018 and 2019, Ohio Environmental Protection Agency's Division of Surface Water (DSW) conducted pre- and post-implementation monitoring for Clean Water Act (CWA) Section 319 (h) and GLRI projects. The Agency is releasing the results from this survey for review and comment. The draft report and appendices are available here. Comments are due by 5:00 p.m. on November 14, 2022 to EPATMDL@epa.ohio.gov.
Ohio EPA DSW: Early Stakeholder Outreach - two Surface Water rules packages
The Section 401 package includes three existing rules as well as a new rule(s). The federal Clean Water Act requires any applicant for a federal permit or license that may result in a discharge to a navigable water to obtain a water quality certification from Ohio EPA pursuant to Section 401. The Wetland Water Quality Standards package includes four existing rules that outline wetland water quality standards that apply to all wetlands within the state. More information on each package can be found here. Comments are due by 5 p.m., January 18, 2023 to dsw_rulecomments@epa.ohio.gov.
