Loss Of Nutrients And Soil From Sandy Pond Tributaries, Oswego County, N.Y., Joseph Makarewicz, Theodore Lewis, Daniel White May 2013

Loss Of Nutrients And Soil From Sandy Pond Tributaries, Oswego County, N.Y., Joseph Makarewicz, Theodore Lewis, Daniel White

Joseph C Makarewicz

North and South Sandy Ponds comprise one of the largest coastal bay ecosystems on Lake Ontario. Unlike South Sandy Pond, North Sandy Pond supports intensive recreational activities and intensive shorefront residential development including a commercial campground and several marinas. Both ponds have an over abundance of nutrients and are the likely cause of the over abundance of aquatic weeds in the water. The limnological literature is quite clear on the causes of this unwanted overabundance of aquatic weeds and microscopic plants – an excess amount of nutrients or fertilizers are entering the water. A short list of possible sources of …

Concentration Of Selected Priority Organic Contaminants In Fish Maintained On Formulated Diets In Lake Ontario Waters, Joseph Buttner, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

Fish were grown in Lake Ontario water under conditions simulating commercial aquaculture and then analyzed for 10 priority organic contaminants. Black bullheads (Ameiurus meias) were grown in cages placed in a bay of Lake Ontario. Rainbow trout (Oncorhynchus mykiss) were grown in terrestrial raceways served with Lake Ontario water. Yearlings were reared on a commercial ration in these systems, which partially isolated them from the contaminant-laden food web and bottom sediments, to an average weight of 93 g for black bullheads (range, 31-220 g) and 213 g (29-558 g) for rainbow trout. Concentrations of contaminants in skinless fillets of both …

Segment Analysis Of Sheldon Creek: The Location Of Sources Of Pollution, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

Considerable concern about the deteriorating condition of Lake Neatahwanta has existed for well over a decade. A goal of the Oswego County Soil and Water Conservation District water quality monitoring program was the development of a statistically defensible database of ecologically important parameters that would allow stewards of the watershed to prioritize and determine which sub-watershed had the largest potential impact on Lake Neatahwanta. After three years of sampling the four creeks draining into the lake, Sheldon Creek, as opposed to Ley, Summerville and Granby Creeks, was determined to be losing the largest amounts of water, soil and nutrients from …

Ecology Of The Lake Huron Fish Community, 1970–1999, Norine E. Dobiesz, David A. Mcleish, Randy L. Eshenroder, James R. Bence, Lloyd C. Mohr, Mark P. Ebener, Thomas F. Nalepa, Aaron P. Woldt, James E. Johnson, Ray L. Argyle, Joseph C. Makarewicz

Joseph C Makarewicz

We review the status of the Lake Huron fish community between 1970 and 1999 and explore the effects of key stressors. Offshore waters changed little in terms of nutrient enrichment, while phosphorus levels declined in inner Saginaw Bay. Introduced mussels (Dreissena spp.) proliferated and may have caused a decline in Diporeia spp. This introduction could have caused a decline in lake whitefish (Coregonus clupeaformis) growth and condition, with serious repercussions for commercial fisheries. Bythotrephes, an exotic predatory cladoceran, and other new exotics may be influencing the fish community. Sea lampreys (Petromyzon marinus) remained prevalent, but intensive control efforts on the …

Chemical Analysis And Nutrient Loading Of Streams Entering Sodus Bay, N.Y, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

In response to public concern created by an abundance of nuisance weeds (i.e. macrophytes) within the three embayments of Wayne County (Sodus, East and Port Bays) , the Aquatic Vegetation Control Program was created in 1987 to develop long-term management strategies for the Bays. The program is administered jointly by the Wayne County Planning Board and the Wayne County Soil and Water Conservation District. The Soil and Water Conservation District recognized early that management of the Bay ecosystem would require the development of a data base presently not available. Toward this end, the Wayne County Soil and Water Conservation District …

An assessment of the Canaseraga Creek watershed was undertaken to determine the nutrient and sediment contribution to the Lower Middle Main Stem of the Genesee River and to determine sources of nutrient and sediment loss geospatially within the Canaseraga Creek watershed. To accomplish this task, a multifaceted, integrated approach was taken by a combination of monitoring, segment analysis, and modeling (Soil and Water Assessment Tool). Thus, the river was monitored for discharge, water chemistry, and loss of nutrients and soil for an entire year (3 August 2010 to 14 February 2012) at the USGS stations at Shaker’s Crossing and Dansville, …


Niagara River Niagara County, New York, Joseph Makarewicz, Matthew Nowak May 2013

Niagara River Niagara County, New York, Joseph Makarewicz, Matthew Nowak

Joseph C Makarewicz

The Niagara River carries water from Lake Erie to Lake Ontario and is the major source of Lake Ontario’s water volume. Famous for the immense Niagara Falls, the 36-mile river is used by over 1 million people in the United States and Canada for functions including drinking water, recreation, and hydropower (Niagara Parks 2009). The Niagara River drains the entire upper Great Lake system into the final lake, Lake Ontario, and due to this huge volume of water has a large potential to change Lake Ontario’s water quality. Nuisance algae, bacterial abundance, and algal mat development along the southern shoreline …

Port Bay Wayne County, New York, Joseph Makarewicz, Matthew Nowak

Joseph C Makarewicz

Located midway between Rochester and Oswego, New York, Port Bay is one of southern Lake Ontario’s larger but relatively shallow (<25 feet) embayments. The perimeter of the bay is primarily residential, but portions of the shoreline and watershed are part of the Lake Shores Marshes Wildlife Area. Wolcott Creek is the major tributary of Port Bay and drains ~27 mi2 of land that is mostly in agriculture. The bay receives treated effluent from the Village of Wolcott Sewage Treatment Plant. Port Bay suffers from cultural eutrophication and is on the New York State 303d list of Impaired Waters due to an overabundance of phosphorus. Benthic anoxia is a major effect of this eutrophication. Port Bay is impacted by nuisance algae, and harmful algal blooms have been observed (Makarewicz et al. 2009). This short report provides a synopsis of …


Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak May 2013

Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak

Joseph C Makarewicz

Irondequoit Bay is approximately 4.2 miles long and 0.6 miles wide and is separated from Lake Ontario by a small barrier beach. Irondequoit Bay had been historically considered hypereutrophic when several sewage plants discharged directly into the bay; however, aggressive restoration by Monroe County has improved the eutrophic state of the bay. Restoration efforts included sealing the bottom sediments with alum, reducing both point and non-point sources of phosphorus, and the pumping of air into the hypolimnion to reduce phosphorus movement from the sediments into the water. Currently no direct sewage plant discharge is received, and phosphorus levels are approaching …
