This document details the method used to develop the Great Lakes Surveillance Framework Watch List.
The United States and Canada adopted phosphorus load reduction targets to combat Lake Erie algal blooms.
The Strategy for the Great Lakes-St. Lawrence River Maritime transportation
The Governments of Canada and the United States are pleased to release the 2019 State of the Great Lakes Highlights Report, which provides an overview of the status and trends of the Great Lakes ecosystem. Overall, Great Lakes water quality is assessed as “fair and unchanging.” While progress to restore and protect the Great Lakes has occurred, including the reduction of toxic chemicals, challenges cited in the report include invasive species and excess nutrients that contribute to toxic and nuisance algae.
As large-scale restoration plans for degraded aquatic habitats evolve, it is essential that multiorganizational collaborations have a common vision to achieve consensus on restoration goals. Development of restoration targets and postrestoration monitoring strategies can be focused using a viability analysis framework that supports an adaptive management process. Resource managers in the corridor can use these results to identify knowledge gaps, research and restoration priorities, and to assess progress towards meeting restoration goals.
Representatives from the United States Environmental Protection Agency and Environment and Climate Change Canada presented on the ongoing efforts to manage excess phosphorus loads leading to toxic and nuisance algal blooms and hypoxia in Lake Erie. The webinar provided a brief overview of information and updates on work under the Nutrients Annex of the Great Lakes Water Quality Agreement (GLWQA) and included presentations by experts from the Nutrients Annex Subcommittee.
This report provides an assessment of progress toward harmonization of prohibited AIS in Great Lakes states and provinces over the last decade, including a comparison of current regulated species lists across the Great Lakes basin to regulations that existed in 2012, the first time that a comprehensive list of all regulated aquatic invasive species was compiled for the basin.
This risk assessment report was conducted to define the priority pathways through which aquatic plant species may move throughout the Great Lakes region and identify gaps in knowledge, management, compliance and law enforcement, and education for these pathways. The results of this risk assessment are intended to guide future activities that may reduce the risk of introduction of aquatic plants into waterways across the Great Lakes region.
The Research Coordination Committee of the Great Lakes Panel on Aquatic Nuisance Species analyzed Great Lakes Restoration Initiative project information to identify trends and gaps in funding for aquatic invasive species projects.
Aquatic invasive species are moved into and throughout the Great Lakes basin through a variety of pathways. The Research Coordination Committee of the Great Lakes Panel on Aquatic Nuisance Species analyzed Great Lakes Restoration Initiative project information to identify trends and gaps in funding for a subset of regionally-prioritized pathways.
Management of established invasive species is imperative to restoring the health of Great Lakes ecosystems. In order to guide research towards the riskiest species, the Research Coordination Committee of the Great Lakes Panel on Aquatic Nuisance Species analyzed Great Lakes Restoration Initiative funding to identify trends and gaps in funding for species-specific projects.
This report summarizes the results of algal bloom tracking efforts by Michigan state agencies in 2017. The survey results will help regulators determine the occurrence and concentration of the cyanobacterial toxin in Michigan surface water supplies.
This 2018 presentation summarizes the GLWA’s work toward converting soluble Phosphorus to particulate Phosphorus during the treatment process using both chemical and biological techniques.
MAEP is a voluntary verification program that helps farmers reduce environmental impacts from their operations by providing technical assistance for the design and implementation of conservation plans. The Overview describes several other indicators of success that speak to water quality outcomes and farmer engagement including participation in training events and tons of sediment and phosphorus loading reduced.
This report provides the recommended updates to phosphorus load targets for Lake Erie, based on several models and consideration of other factors that affect Lake Erie water quality.
The Lake Erie Protection & Restoration Plan 2016 reflects the state of Ohio’s priorities to protect, preserve and restore Lake Erie. The purpose of the plan is to identify the state’s strategic direction for Lake Erie and the Lake Erie watershed to achieve established environmental, recreational, and economic goals.
In 2007, the Ohio Environmental Protection Agency convene the Ohio Lake Erie Phosphorus Task Force to identify and evaluate potential point and nonpoint sources of phosphorus to Ohio tributaries; determine what practices may have changed since 1995 that could increase dissolved reactive phosphorus (DRP) loads; examine various aspects of agriculture that might influence the increase in DRP loads; review the possible/probable relationships of the increased DRP loads to the eutrophication problems that have returned to Lake Erie (particularly the western basin); consider the impacts of zebra a
The Ohio Lake Erie Phosphorus Task Force Phase II effort built on the work of the 2010 Phase I report by incorporating newly available information and including more stakeholders with additional areas of expertise. The purpose of Phosphorus Task Force Phase II is to 1) develop reduction targets for total and dissolved reactive phosphorus that can be used to track future progress, and 2) develop policy and management recommendations based upon new and emerging data and information.
The Centers for Disease Control and Prevention (CDC) compiled information on illnesses associated with HABs.
The AWWA maintains a resource page for communities to access material related to source water protection, including toolkits, research, guidance, and additional resources.
