This guide is designed to provide information on the ecological values and problems associated with aquatic macrophytes, to present methods used to control the troublesome species, and to provide suggestions on how to implement a lake management plan that would deal with macrophytes as legally and as safely as possible.

Water Chemistry Of The North And South Basins Of Conesus Lake, Joseph Makarewicz, Isidro Bosch, Theodore Lewis

Joseph C Makarewicz

The objective of this study was to determine if there were differences in the chemistry of the north and south basins of Conesus Lake during the summer stratification period. To achieve this objective, water samples were taken from 18 May to 2 November 2000 from both basins.

Population Studies Of Eurasian Watermilfoil ( Myriophyllum Spicatum ) And Zebra Mussels (Dreissena Polymorpha) In Conesus Lake, N.Y. (Summer 2000), Isidro Bosch, Joseph Makarewicz, Jennifer Emblidge, Douglas Johnson, Michael Valentino

Joseph C Makarewicz

The primary goal of our research during the summer 2000 was to examine the distribution and density Eurasian watermilfoil beds and of populations of zebra mussels in Conesus Lake. The results of this study improve our knowledge of these populations and contribute to the scientific foundation required for consideration of possible management strategies. A secondary goal of this project was to extend our long term database on macrophyte growth at two sites first studied by Herman Forest and his colleagues in 1967.

The Development Of An Stream Water Quality Assessment Index To Evaluate Stream Health Conesus Lake Tributaries Spring 2011, Joseph Makarewicz, Theodore Lewis, Blake Snyder

Joseph C Makarewicz

The major goal was to develop an assessment tool for watershed health utilizing the USDA data base. Such a tool would allow the county to evaluate the status of watersheds; that is, are they improving, getting worse, or not changing. An evaluation tool of this type would allow further development and direction of the Conesus Lake Watershed Management Plan.

Monitoring of two of the USDA streams (Cottonwood Gully and North McMillan Creek) was changed to the spring rather than the summer. This was done as a result of last year’s work which suggested that spring monitoring may provide a better …

Water Quality Of Conesus Lake, 1985-1986, Joseph Makarewicz, Herman Forest

Joseph C Makarewicz

An intensive study of Conesus Lake and its tributaries was undertaken between April 1985 and December 1986 with the following general objectives: (1) To evaluate the water quality of Conesus Lake, the source of drinking water for the Town of Livonia and the Villages of Geneseo and Avon; (2) To identify, if possible, water of lower turbidity within the lake; (3) To identify, if possible, causes of higher turbidity in raw water intakes of the Livonia and Geneseo water treatment plants; (4) To evaluate what effect, if any, the construction of a perimeter sewer has had on nutrient levels within …

Soil And Nutrient Loss From Selected Subwatersheds Of Conesus Lake, Joseph Makarewicz, Isidro Bosch, Theodore Lewis

Joseph C Makarewicz

The purpose of this study was to evaluate the loss of soil and nutrients from the upland area of ten selected small watersheds or subwatersheds surrounding Conesus Lake. Macrophyte beds of mixed composition exist around the entire edge of Conesus Lake – perimeter beds. In addition, macrophyte beds consisting mainly of Eurasian milfoil exist at or near many of the creek mouths within the littoral zone of Conesus Lake. These creek-mouth associated beds are of interest because their presence may be associated with creeks that lose a large amount of nutrients and soils from their subwatershed.

The Impact Of Stream Nutrient Loading On Macrophytes And Metaphyton In Conesus Lake, Usa, Peter D’Aiuto, Joseph Makarewicz, Isidro Bosch

Joseph C Makarewicz

During the summers of 2000, 2001 and 2002, the littoral zone of Conesus Lake (40°54'N, 77°43'W) supported massive blooms of metaphyton, mostly filamentous green algae (Zygnema sp. and Spirogyra sp.). Extensive agricultural activity (60–80% of the land use) within the lake’s western subwatersheds is responsible for the loading of large quantities of nitrate (up to 1800 g/ha/day) and total phosphorus (up to 34 g/ha/day) into the lake during precipitation events (MAKAREWICZ et al. 2001). Large assemblages of M. spicatum and accompanying metaphyton growth were often located near stream mouths (Fig. 1) and a significant correlation existed between stream nutrient loading …

Conesus Lake Limnology 2009: Water Quality Of Usda Monitored Watersheds Internal Hypolimnetic Phosphorus Loading Lake Chemistry Status Of The Zooplankton Community, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

During the summer of 2009, Conesus Lake monitoring conducted by The College at Brockport determined the current status of the health of the lake to determine if any changes (improvement or further degradation) had occurred. To accomplish this goal, the following were completed: a trophic state assessment of the lake, an estimate of the internal loading of the lake’s phosphorus budget, an estimate of phosphorus loading from streams, an evaluation of long-term trends in lake chemistry, an evaluation of the walleye stocking program on lake zooplankton, and the continued long‐term evaluation of nutrient and soil losses from eight agricultural subwatersheds. …

Trophic Interactions: Changes In Phytoplankton Community Structure Coinciding With Alewife Introduction (Alosa Pseudoharengus), Joseph Makarewicz

Joseph C Makarewicz

Conesus Lake is a eutrophic lake (MILLS 1975) and the most western of the Finger Lakes of New York State, USA. Abundance of a top level predator, the walleye (Stizostedion vitreum vitreum), decreased from a high of 12,000 individuals in 1966 to 9,614 individuals in 1975 to 1,850 individuals by 1985 in Conesus Lake (ABRAHAM 1989). Coincidental with the decline of the walleye in Conesus Lake was the proliferation of an obligate planktivore, Alosa pseudoharengus (ABRAHAM 1988). During the late 1970s (probably 1978 or 79), the alewife was accidentally introduced and became established in the lake. The pre-alewife zooplankton community …

Stream Water Quality Assessment Of Long Point Gully, Graywood Gully, And Sand Point Gully: Conesus Lake Tributaries Spring 2012, Joseph Makarewicz, Theodore Lewis, Dale Pettenski

Joseph C Makarewicz

In 2011, Cottonwood Gully and North McMillan Creek were monitored to determine the status of these two watersheds of Conesus Lake using the newly developed Stream Water Index. In 2012, the goal was to implement the assessment tool in three additional watersheds: Long Point Gully, Sand Point Gully and Graywood Gully. The implementation of this tool allows the county to evaluate the status of Conesus Lake watersheds over time; that is, are they improving, getting worse, or not changing. An evaluation using a tool of this type should provide further direction to the Conesus Lake Watershed Management Plan.

Conesus Lake Tributaries, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

After several years of a general decrease in “concentrations” of various nutrients from managed watersheds, substantial increases in the concentrations of nutrients and soil particles were observed in streams during the summer of 2009 (Makarewicz and Lewis 2009). At Graywood Gully, for example, concentrations of soil (TSS), total phosphorus (TP), soluble reactive phosphorus (SRP), total Kjeldahl nitrogen (TKN), and nitrate increased in the stream water. At Cottonwood Gully, after a 5-year decrease, nitrate concentration (NO3+NO2) increased to levels not observed since 2003. Similar increases were observed in the Southwest, Sand Point, North Gully, Sutton Point and Long Point subwatersheds. Several …

Update Of Soil And Nutrient Loss From Subwatersheds Of Conesus Lake - 2001, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

The State of Conesus Lake: Watershed Characterization Report (2001) identified areas that required additional data to evaluate the current state of the Conesus Lake watershed. A comprehensive update of nutrient and soil loss from all of the major subwatersheds from a study undertaken in 1990-91 (Makarewicz et al. 1991) was listed as a high priority. This study was designed to estimate discrete losses of total phosphorus and total suspended solids in eighteen subwatersheds during the calendar period April to December under both baseline and event conditions. Results of this study will be the ability to assess the change in nutrient …

Joseph C Makarewicz

A program of research was developed at the State University of New York at Brockport's Department of Biological Sciences to investigate the causes of decreasing water transparency and increased salt levels in some streams draining into Conesus Lake and to identify watersheds and sources of. fertilizers that may be polluting the lake and causing increased abundance of "weeds". It has been supported by New York State, Livingston County, the Villages of Avon and Geneseo and the Town of Livonia and many private citizens. The thrust of the research has been to gather and synthesize information necessary to determine the physical …
