Dissolved reactive phosphorus comes from agricultural fertilizer and nutrient polluted runoff. The City of Rochester said the line affected is a Holley line, which is used for fire services. The western basin is very shallow, with an average depth of 7.4 metres (24 ft) and a maximum depth of 19 metres (62 ft). Winrock International Institute for Agricultural Development ($500,000) for agricultural watershed management implementation.

Unfortunately, in the western Lake Erie region, heavy clay soils often develop cracks and pores that act like the drain in your bathtub: surface water quickly drains through the soil into the tile drain, carrying high concentrations of phosphorus with it. In other words, algae can easily consume dissolved phosphorus, leading to rapid algal growth. Cover crops and buffer strips may also reduce runoff from surface soils. The most commonly occurring groups of freshwater algae are diatoms, green algae, and blue-green algae, which are more correctly known as cyanobacteria. The shallowness of the basin and the warmer temperatures make it the most biologically productive of the Great Lakes. Dissolved phosphorus from agricultural runoff is the primary driver of Lake Erie’s harmful algae outbreaks, and a recent report from the USDA-NRCS shows that 84% of phosphorus applied to agricultural land in the Lake Erie Basin is from commercial fertilizers, and 16% is from manure. If people work together to reduce phosphorus pollution, Lake Erie can and will recover. The scientists plan on modeling Lake Ontario over the next few years. The central basin is quite uniform in depth, with an average depth of 18.3 metres (60 ft) and a maximum depth of 25 metres (82 ft). from Lake Erie Binational Nutrient Management Strategy, 2011. After the water crisis, “people started to ask questions,” says Miller.

For the past forty years, scientists at Heidelberg University’s National Center for Water Quality Research have been measuring pollution in the rivers and streams that feed Lake Erie. These controls represented an unprecedented success in producing environmental results through international cooperation. Open lake phosphorus concentrations declined due to the joint efforts made.

Recently, algal blooms have once again tainted western Lake Erie with unhealthy, sometimes toxic, green slime. Note that in the Cuyahoga River basin, phosphorus concentrations (shown as brown dots) remained mostly level despite large spikes in water flow (shown as blue spikes) after heavy rains. Technically, Lake Erie is not a “dead” lake, it is just filled with the wrong type of life, such as algae, that causes the death of other organisms, which create a “dead zone”. Why is this happening? About one-third of the total population of the Great Lakes basin is in the Lake Erie watershed. A new study shows that hundreds of tons of plastic are building at the bottom of the Great Lakes and Lake Erie alone has about 380 tons of plastic. That may give a clue into how some plastic could travel over Niagara Falls from Lake Erie to Lake Ontario. Here are some of the many opportunities for reducing phosphorus pollution while preserving farmland productivity. However, the Bills bet of -??? About one third of the total population of the Great Lakes basin resides within the Lake Erie watershed. What works for one farm or livestock operation might not work for another, and changing the way farmers do business could have large economic costs.

Just as there’s no “one size fits all” solution, the options for reducing nutrient pollution can change over time.

IPM Institute of North America ($408,150) for agricultural watershed management implementation. Outbreaks of cyanobacteria that release toxins are commonly called “toxic algae” blooms. Tile drains are simply drain pipes buried beneath fields to help lower the water table and collect surface water after it has filtered through a few feet of soil and then whisk it away from the fields to avoid standing water and surface runoff. Particulate Phosphorus will generally settle out of the water column and not be bioavailable to cyanobacteria and other organisms. ROCHESTER, N.Y. (WROC) – A water main break shut down part of W Main Street in Rochester on Saturday between Plymouth Avenue and State Street/ Exchange Streets. There are two categories of pollution that contribute to Lake Erie’s phosphorus loads: pollution from point sources like pipes from factories or water treatment plants, and non-point sources like runoff from fields. *NOTE: Some municipalities send some of this surface runoff into combined sewer systems that lead to sewage treatment plants. In general, point sources are associated with water use for domestic, commercial and industrial purposes, while nonpoint sources are associated with the interaction of land use activities and the hydrological cycle. Plastic has been found in every aspect of our lives, but it still has not shown to alter health. Certain plastics do evolve as they enter into water as some fall apart and sinks while others may turn into microbeads. Dissolved phosphorus is a special problem in Lake Erie because it is much more “bioavailable” to algae than particulate phosphorus. However, these systems are very expensive and not infallible. A large portion of the western Lake Erie watershed was originally the Great Black Swamp. In this video, research scientist Laura Johnson of the National Center for Water Quality Research at Heidelberg University explains how 40 years of data points to dissolved reactive phosphorus as the primary culprit behind Lake Erie’s harmful algal outbreaks. Several different types of plastics were analyzed as some have different buoyancies. Both surface runoff and tile drains empty into ditches that lead to streams, which lead into rivers, which ultimately empty into Lake Erie, delivering damaging loads of phosphorus. In part this is because agriculture is exporting a small amount of the phosphorus that is applied and many farms are at recommended soil test phosphorus levels. Exposed agricultural and urban lands, particularly in southwest Ontario and northwest Ohio, contribute immense sediment loads to the lake. © 1998 - 2020 Nexstar Inc. | All Rights Reserved. “Plastic is definitely changing the bottom of our lakes,” said Hoffman. Stratification impacts the internal dynamics of the lake physically, biologically and chemically, and this in turn affects the amount of dissolved oxygen present at the bottom of the lake.

Algae can persist for weeks during summer by blooms carried by winds and currents eastward through the lake. Lake Erie is the smallest of the Great Lakes by volume and also the shallowest. Plastic is no stranger to the Great Lakes and studies have shown and mapped how certain plastics move at the surface. Making the wrong kinds of changes might not make things better for Lake Erie – it could even make things worse. There were a few easy bets on our way to 3-3, with the Dolphins winning straight-up and the Texans and Jaguars going way under. During the 1960s water quality issues in the Great Lakes became a concern and Lake Erie was perceived to be \"dying\". Of all the Great Lakes, Lake Erie is exposed to the greatest stress from urbanization, industrialization and agriculture. Dr. Jeffrey Reutter, Former Director of and Special Advisor, Ohio Sea Grant Program and F.T. Farmers are ready and willing to do the right thing and USDA is working hard to provide incentives focused on dissolved phosphorus reductions, such as holding back runoff water and better fertilizer management.

This fuels a bumper crop of algae each year that can make water toxic to fish, wildlife, and people.
