LimnoTech Scientists Contribute to Lake Erie Phosphorus Reduction Study (March 2016)
LimnoTech’s Dr. Joseph DePinto, Todd Redder and Chelsie Boles are contributing authors to a report released today addressing possible solutions to problems resulting from excess phosphorus in Lake Erie. The report discusses potentially effective cropland management scenarios developed by agricultural and environmental experts to reduce the phosphorus load to Lake Erie. This excess phosphorus has caused an oxygen-depleted “dead zone” and toxin-producing algal blooms in the lake like the bloom that shut down the City of Toledo’s drinking water supply in 2014. The goal of U.S. and Canadian governments is a 40% reduction in 2008 phosphorus loads. The new study produced by the University of Michigan Water Center integrates results from six modeling teams, including LimnoTech, and concludes that meeting the phosphorus reduction target will require widespread use of strong agricultural conservation and management practices, including fertilizer-management, conversion of some cropland to grassland, and more targeted best management practices. The report is titled Informing Lake Erie Agriculture Nutrient Management via Scenario Evaluation. Report Video

LimnoTech Co-Authors Fish Behavioral Study (August 2015)
LimnoTech staff are co-authors of a recently published study titled “Behavioral and physiological responses of Largemouth Bass Micropterus salmoides to rain-induced reductions in dissolved oxygen in an urban system.” The project sought to understand the response of fishes in urban water systems to hypoxia caused by wet weather discharges. Study elements included tracking the movement of largemouth bass in the Chicago Area Waterway System (CAWS) using internal acoustic transmitters and acoustic telemetry arrays, and conducting a concurrent laboratory study of the same species to understand physiological responses of fishes to depressed DO conditions. During the second year of the study, externally mounted DO tags were placed on free-swimming fishes to understand actual DO exposure at the scale that the fish experience during wet weather events. Authors were Doug Bradley, Penelope Moskus, and John Wolfe (all from LimnoTech), and Greg Gaulke, David Wahl, and Cory Suski. Link
Bradley Co-Author of Ecological Indicators Article Examining RNA:DNA Technologies for Larval Fish Assessment (July 2015)
When cooling water intake systems draw from rivers, lakes and other waterways, large numbers of fish eggs and larvae are entrained within the waters. These fragile fish are then subject to physical, thermal and chemical stress, or even direct or indirect mortality. A recently published study co-authored by LimnoTech’s Doug Bradley, and Carolyn J. Foley and Tomas O. Höök of Purdue University, examines the potential use of RNA:DNA ratios to index the condition of entrained larval fish at the time of entrainment, and could shed light on the impacts of entrainment on early life stage fishes. The study suggests that the RNA:DNA ratio method shows promise as a quick and efficient means of determining fish condition, and may provide a powerful, supportive tool in assessing the effects of entrainment on fish populations.

NOAA, Research Partners Predict Severe 2015 Harmful Algal Bloom for Lake Erie (July 2015)
LimnoTech’s Western Lake Erie Ecosystem Model (WLEEM) is one of three models being used in an ensemble modeling approach by the National Oceanic and Atmospheric Administration (NOAA) and its research partners to forecast the severity of the 2015 Harmful Algal Bloom (HAB) in the Western Basin of Lake Erie. The models predict that the 2015 western Lake Erie harmful algal bloom season will be among the most severe in recent years as a result of heavy June rains causing substantial nutrient runoff. The effects of the cyanobacterial blooms can include higher costs for local governments to treat drinking water, risks to swimmers in high-concentration areas, aesthetic nuisance to boaters, and disruption of the health and integrity of the ecosystem’s food web that supports its world-class sport fishery.

Data Sensors Help Lake Erie Water Treatment Plants with Real-Time Information (May 2015)
This week LimnoTech field crews will be placing water quality sensors, data sondes, in the waters of Lake Erie close to several water intake systems. These water quality sensors will provide real-time data to water treatment plant personnel to help them in adjusting treatment processes. LimnoTech will work with treatment plants to get the sensors up and running, and to integrate the sensors into the plants’ data management and process control systems. Now when a potentially toxic bloom moves in, as it did in the summer of 2014, the continuous algae data from the sensors will give treatment plant operators time to ramp up treatment procedures to ensure that water is safe to use. Also, with more timely information provided by the sensors, operators can fine-tune their treatment procedures to keep the water clean while saving money. Article

New Lake Temperature Database Published by Global Collaboration of Scientists including LimnoTech Staff (March 2015)
LimnoTech scientists Dr. John Lenters, Dr. Noémi Barabás, and Dr. Dendy Lofton are part of the Global Lake Temperature Collaboration (GLTC), an international group assembled to provide increased access to global lake temperature records. The GLTC group recently published an article summarizing a new lake temperature database in the journal Scientific Data, which is published by Nature (http://www.nature.com/sdata/). Since its inception in 2010, the GLTC project has recognized that a new global database of lake surface temperatures was needed, including not only satellite data, but also “on the ground” measurements from in situ data collection programs. Over the years, the GLTC initiative has grown to more than 70 investigators from 20 countries, assembling a water temperature database for 291 lakes and reservoirs worldwide. The database provides summer-mean lake surface temperatures from 1985-2009, roughly doubling the amount of data previously available from satellites alone. The new GLTC dataset represents the first publicly available global compilation of in situ and satellite-based lake surface temperature data. The database also provides information on climatic drivers (air temperature, solar radiation, and cloud cover), as well as geomorphometric characteristics that may affect lake temperature (latitude, longitude, elevation, lake surface area, maximum depth, mean depth, and volume). This unique global dataset will offer an invaluable baseline perspective on lake thermal conditions for ongoing and future studies of environmental change.

LimnoTech Provides Major Contribution to University of Michigan Report on Lake Erie Nutrient-Driven Hypoxia (February 2014)
The University of Michigan recently released a press release on its EcoFore-Lake Erie project, a study that documents recent trends in Lake Erie's health. The report offers guidance to reducing the size of toxic algae blooms and oxygen-starved regions called hypoxic zones, or dead zones—two related water quality problems that have seen a resurgence in Lake Erie since the mid-1990s. The study recommendations are aimed at policymakers who will update the binational Great Lakes Water Quality Agreement. A 2012 protocol amending the 1972 agreement commits the United States and Canada to revising phosphorus targets for open waters and near-shore areas of each Great Lake, and taking actions to reduce phosphorus levels that contribute to harmful algae.
The study was overseen by the University of Michigan and involved 28 authors from numerous educational institutions and scientific agencies. LimnoTech scientists Dr. Joseph DePinto and Dr. Daniel Rucinski provided significant contributions to the study and were co-authors on the paper. The study is accepted for publication in a forthcoming edition of the Journal of Great Lakes Research, and is titled "Assessing and addressing the re-eutrophication of Lake Erie: Central Basin Hypoxia."

LimnoTech Leads Development of Technical Basis for Nutrient Water Quality Standards Review in Truckee River, NV (January 2014)
A triennial review of numeric nutrient water quality standards being conducted by the Nevada Division of Environmental Protection (NDEP) will be informed by a technical analysis recently completed by LimnoTech. The effort has been a collaboration of a third-party-driven working group that includes the City of Reno, City of Sparks, Washoe County, Truckee Meadows Water Authority [TMWA], NDEP, and USEPA.
The foundation of the technical effort is the application of a set of watershed (WARMF) and river (TRHSPF) water quality models, developed by LimnoTech, that examine the linkage between instream nutrient concentrations, periphyton (attached algae) and response of the river in terms of dissolved oxygen concentrations. LimnoTech incorporated peer-reviewed empirical and theoretical equations into TRHSPF to improve the simulation periphyton. The models were used to better understand the nutrient‐DO criterion compliance relationship in the Truckee River. This information will help NDEP identify appropriate numeric nutrient water quality criteria that are protective of beneficial uses. The Truckee River has historically been challenged within the State of Nevada by a limited water supply and competing water demands. LimnoTech’s technical effort involved extensive engagement with watershed stakeholders including municipalities, Native American tribes, irrigation districts and the general public. It is anticipated that the after NDEP completes the triennial review process for the nutrient water quality standards, the effort will progress towards a review of the existing nutrient TMDL.

Fox River Watershed Protection Implementation Plan (November 2013)
The Fox River Study Group (FRSG) is a group of stakeholders with the vision of restoring and protecting water quality in the Fox River (in Illinois) while fostering sustainable growth throughout the watershed. The rapid pace of development in the Fox River watershed requires comprehensive planning to maintain this resource. The FRSG contracted with LimnoTech to develop a comprehensive Implementation Plan (IP) that will recommend actions for improvement of low dissolved oxygen and excessive algal growth.
The Fox River drains 938 square miles in southeastern Wisconsin before entering Illinois. Between the Wisconsin border and the confluence with the Illinois River, the river runs for 115 miles and drains an additional 1,720 square miles. The Fox River is a multi-purpose resource that contributes critical habitat for wildlife, serves as a valuable resource for recreation, receives and assimilates pollutants from point and nonpoint sources, and provides source water for public water supplies. The entire length of the river in Illinois was placed on the State’s 303(d) list in 2002. The most frequent causes listed are flow alteration, habitat alteration, low dissolved oxygen, nutrients, organic enrichment, PCBs, siltation or suspended solids.

LimnoTech on Two Teams Awarded UM Water Center Projects (September 2013)
LimnoTech was recently awarded two projects through a grant program conducted by the University of Michigan. The University of Michigan Water Center awarded eight research grants, totaling nearly $2.9 million, to support Great Lakes restoration and protection efforts. The Water Center has provided more than $3.4 million in research funds since it formed last October. The latest two-year grants were awarded to multidisciplinary teams selected from 90 proposals. LimnoTech’s projects involve work in Green Bay in Lake Michigan and Saginaw Bay in Lake Huron. The two projects are:
Restoring the health of the Green Bay ecosystem under a changing climate: Modeling land use, management and future outcomes. Led by J. Val Klump, University of Wisconsin-Milwaukee, this project concerns algae-promoting nutrients flowing into the southern end of Wisconsin's Green Bay have resulted in oxygen-starved regions known as hypoxic zones. The project will integrate watershed and lake computer models to test how current restoration efforts will perform under climatic changes and to determine if additional actions are needed to achieve restoration goals for the bay. LimnoTech’s role will be to work with other models to link its Advanced Aquatic Ecosystem Model (an advanced eutrophication-hypoxia model) to the existing Green Bay hydrodynamic model to create a framework that can quantify the bay response to alternative land management scenarios developed by the watershed modeling team. LimnoTech will also assist the team in building a Management Analysis Tool that will provide easy and understandable access for system managers to scenario model results.
Saginaw Bay optimization decision tool: Linking management actions to multiple ecological benefits via integrated modeling. Led by David Karpovich, Saginaw Valley State University, this project seeks to synthesize and build on other projects funded by the federal Great Lakes Restoration Initiative and the Michigan Agriculture Environmental Assurance Program aimed at reducing nutrient runoff from agricultural land into Michigan's Saginaw Bay. This Water Center-funded study will include a retrospective assessment of GLRI and MAEAP projects within the Kawkawlin and Pigeon/Pinnebog river sub-watersheds. The project main objective will be to develop an integrated modeling framework that can serve as a decision tool for strategically allocating restoration resources and conservation practices to benefit multiple ecological endpoints in the system. LimnoTech will serve the role of Saginaw Bay watershed loading modelers and Saginaw Bay modelers for the project. LimnoTech will also participate in the stakeholder process by assisting in the formulation and modeling of management scenarios for the system and synthesizing those results into a management decision tool for assessment and comparison of restoration/management alternatives.

LimnoTech Helps Launch Great Lakes Data Buoys (May 2013)
LimnoTech is again helping to deploy data buoys in the Great Lakes this year. These real-time weather buoys are equipped with state-of-the-art sensors and technology. Every ten minutes the buoys report the average wind speed, direction, gust, air temperature, relative humidity, air pressure, wave height and period, and water temperature.
The first weather buoy was deployed during the first week of May off the coast of Holland, MI (45029). It will be relocated halfway between Holland and Grand Haven later this month with assistance from NOAA's Great Lakes Environmental Research Lab in Muskegon. This buoy was funded by the Great Lakes Observing System (GLOS) through a grant from the NOAA Coastal Storms Program. Another buoy was deployed off Monroe, MI, in Lake Erie (45165) with support from the U.S. Army Corps of Engineers.
Observations from both buoys can be obtained from several sources for free. All of the parameters measured by the buoy are available on the Upper Great Lakes Observing System (UGLOS) website. Data from the buoys are also available on the GLOS data portal website,and through the NOAA National Data Buoy Center.

DePinto, Verhamme, and Redder Contribute to Great Lakes Climate Effects Research Study
LimnoTech’s Joseph V. DePinto, PhD, Ed Verhamme, and Todd Redder are part of a collaborative research team, supported by the National Science Foundation (NSF), and including researchers from Stanford University’s Carnegie Institute of Science, the University of Michigan, Heidelberg University, Grace College, the University of Toledo, and the NOAA-Great Lakes Environmental Research Laboratory. The goal of the research project is to answer the question: “What are the possible effects of climate-change-induced extreme events on water quality and ecology in the Great Lakes system, and what management strategies will be effective in addressing these changes?” The project team is investigating and synthesizing various components of the whole problem, including atmospheric modeling of climate change, effect of extreme events on watershed sediment and nutrient loading, in-lake response to extreme event-driven changes in atmospheric and nutrient loading conditions, socio-economic responses and adaptation to the environmental changes, and education/outreach on this problem. The project team is using the Western Lake Erie Basin (watershed and Western Basin of Lake Erie) as its study site for this project. LimnoTech’s part in this project is providing the in-lake water quality and algal bloom response modeling for this study.
In 2011, the Western Basin of Lake Erie experienced the largest harmful algal bloom in Lake Erie’s recorded history, with peak intensity over three times greater than any previously observed bloom. That occurrence provided an excellent opportunity for the NSF project team to investigate the contributing cause-effect relationships for this extreme event. This part of the overall study led to a peer-reviewed publication entitled, “Assessing the Effects of Climate-Change-Induced Extreme Events on Water Quality and Ecology in the Great Lakes,” which will be published soon in the Proceedings of the National Academy of Sciences. The findings of the study and the paper generated by it are now posted on the Project website.

LimnoTech Paper is One of Most Cited (May 2010)
A LimnoTech paper was recently recognized as one of the "Top-20 most cited articles" published in Journal of Great Lakes Research from 2005-2009. The authors of the paper, “Modeling the role of zebra mussels in the proliferation of blue-green algae in Saginaw Bay, Lake Huron,” include current LimnoTech employees Victor J. Bierman Jr., Joseph V. DePinto and David W. Dilks. Blooms of Microcystis, a toxin-producing blue-green alga, had all but been eliminated from Saginaw Bay in the early 1980s because of controls on phosphorus loadings from the watershed, but have re-occurred in the bay most summers since the early 1990s even though these loadings have not increased. The paper describes use of an ecosystem model to explain how zebra mussels could have caused the re-occurrence of these blue-green algal blooms because of their impacts on phytoplankton community structure and/or on internal phosphorus loadings from the sediments. paper

This was a significant exchange of information, as excessive nutrient enrichment is increasingly being recognized as a major threat to the quality of surface water resources in the United States. The forum was sponsored by the Lake Erie Millennium Network, a part of the Great Lakes Regional Research Information Network.Dr. DePinto gave a presentation (see link below) on two large modeling efforts being conducted by LimnoTech to support management decisions concerning control measures for eutrophication in Lake Erie. Other LimnoTech staff working on these projects include Todd Redder, Dan Rucinski, Ric McCulloch, Jeremy Grush, and Brian Lord. pdf
LimnoTech Takes Water Footprinting Expertise to India (January 2010)
LimnoTech’s Wendy Larson recently traveled to India as a member of the International Finance Corporation’s (IFC) Water Footprinting Team. The purpose was to conduct a workshop and launch a water footprint initiative with Jain Irrigation that will allow the company to measure its environmental and sustainability benefits, and identify ways to reduce water consumption. Wendy and the others in her group toured farms in the region where drip irrigation technology is being applied. IFC, a member of the World Bank Group, fosters sustainable economic growth in developing countries by financing private sector investment. Jain Irrigation has pioneered water conservation and the use of water-saving devices in India.
LimnoTech Contributes to EPA Sediment Guide (November 2009)
U.S. EPA has released its second Sediment Assessment and Monitoring Sheet, titled, "Understanding the Use of Models in Predicting the Effectiveness of Proposed Remedial Actions at Superfund Sediment Sites." This document is a primer for those not experienced in the development and use of models at sediment sites. It explains the typical objectives of modeling, how models are built, how they are used to predict the effectiveness of remedies, and how the uncertainty in model predictions can be addressed. John Wolfe, Ph.D., P.E., BCEE, and Tim Dekker, Ph.D., P.E., Senior LimnoTech Environmental Engineers, were major contributors to this document, which is now available on the EPA website. With EPA, Tim and John prepared document drafts and developed revisions to respond to comments from each of the EPA regions. Their work has been well received and much appreciated at EPA, as well as by the regulated community. This document is available at: http://www.epa.gov/superfund/health/conmedia/sediment/pdfs/Modeling_Primer.pdf
LimnoTech Projects Recognized in Professional Publications (June 2009)
Two LimnoTech projects have been featured recently in professional publications. The first involved LimnoTech’s contribution as part of a large NSF-funded collaborative research project led by The Ohio State University. The overall project examined interactions between lake ecosystems and lake-related human activities in Lake Erie, and it was featured in 2009 Spring/Summer issue of Twine Line magazine, an Ohio Sea Grant publication. The article, titled “Biocomplexity: Uncovering Lake Erie’s Physical, Biological, and Economic Connections,” (pdf) was written by Stacey Brannan. Joe DePinto, Ph.D., Dan Rucinski, Ed Verhamme, and Todd Redder of LimnoTech were part of the project team involved in developing complex fine-scale models to explore how human-lake interactions affect human-lake dynamics. The second article appears in Minnegram, a publication of the Minnesota Water Resources Center, and is titled “Model Will Allow Managers to Forecast Impact of Policies on Toxic Chemicals in the Great Lakes,” (pdf) by Nina Shepard. This project, a collaborative effort between LimnoTech and the University of Minnesota, was again led by Joe DePinto, and involved developing a screening-level, multi-media chemical exposure model for the entire Great Lakes Basin that will allow water resource managers to anticipate basin-wide risk from emerging chemicals of concern.

LimnoTech Works with Chinese Experts to Solve Environmental Challenges (January 2009)
LimnoTech staff are involved in several exciting projects and initiatives in China. First, we are conducting several workshops in China to provide training to Chinese experts and regulators in the use of watershed management and Total daily Maximum Load approaches for restoring and protecting water quality. The focus has been on transboundary issues (involving large areas and multiple cities and provinces), and has also focused on southern provinces involving China’s largest watersheds and industrial areas that are experiencing extreme water quality problems, impacting ecologic conditions and causing major disruptions in water supply for millions. This is a cooperative program in which we are teaming with experts from Australia and Canada. LimnoTech staff are also supporting the early stages of research efforts with Chinese research institutes on capping contaminated sediments, and the development of green eco-cities approaches to planning for Chinese cities.
