“…This differs from previous work by Conroy et al that did not find significant effects of weather during the stratified summer [26]. In another study, modeling results suggested that the largest driver of hypoxia in Lake Erie since the mid-1990s is the phosphorus load, with meteorological conditions having a minimal influence [7]. A primary difference between this study and previous work is that this study focuses on observational data on discrete time intervals rather than a combination of both real and simulated data at a higher frequency.…”

Hypoxia, low dissolved oxygen (DO) concentrations (<2 mg/L), has been a major issue in Lake Erie for decades. While much emphasis has been placed on biological factors, particularly algal blooms, contributing to hypolimnetic oxygen depletion, there has been little focus on the role of weather. For this study, we monitored water temperature and DO concentrations at sites in the western, central, and Sandusky basins in Lake Erie during June and July 2010-2012. We then compared trends in stratification and DO concentrations to weather patterns during that period. We found that during those three years, there was significant variation in weather patterns, particularly decreased ice coverage and increased storm events in 2012. These weather patterns corresponded to 2012 having the warmest water temperatures, some of the lowest DO concentrations, and a deeper and thinner hypolimnion (especially in the central basin) than the previous years. We found a relationship between weather and hypoxia, providing further evidence for why these basins are susceptible to low DO conditions during summer months. The role of weather in hypoxia is another indication that the lake is vulnerable to effects of climate change and should be considered in management strategies.

“…Lake Erie, due to the high influx of nutrients from tributaries, such as the Maumee and Sandusky Rivers, is able to support high species diversity [7]. This makes Lake Erie a center for fishing and tourism with an annual revenue of over 10 billion dollars and employing over 100,000 people [8].…”

“…Now, these details can be shared (via the Internet and databases such as Access) with those who wish to incorporate GIS into their analyses or work with subsets of the loads. These estimates can be used by modelers who wish to include more spatial detail in mass balance (Chapra and Dolan, 2012) or ecosystem (e.g., Pauer et al, 2011;Rucinski et al, 2010;Schwab et al, 2009) models. They can also be used to make inferences about the geographical nature of the loading trends.…”

“…These load reductions resulted in a rapid and profound ecological response as predicted by a range of models (8)(9)(10). Despite early success from these management actions, however, hypolimnetic oxygen depletion rates, hypoxia extent (11,12), and algal biomass (13)(14)(15) have increased systematically since the mid-1990s. Of greatest concern is the increase in toxin-forming strains of the cyanobacteria Microcystis sp.…”

Record-setting algal bloom in Lake Erie caused by agricultural and meteorological trends consistent with expected future conditions

In 2011, Lake Erie experienced the largest harmful algal bloom in its recorded history, with a peak intensity over three times greater than any previously observed bloom. Here we show that long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and that these trends, coupled with meteorological conditions in spring 2011, produced record-breaking nutrient loads. An extended period of weak lake circulation then led to abnormally long residence times that incubated the bloom, and warm and quiescent conditions after bloom onset allowed algae to remain near the top of the water column and prevented flushing of nutrients from the system. We further find that all of these factors are consistent with expected future conditions. If a scientifically guided management plan to mitigate these impacts is not implemented, we can therefore expect this bloom to be a harbinger of future blooms in Lake Erie.extreme precipitation events | climate change | aquatic ecology | Microcystis sp. | Anabaena sp.
