• Allen Creek Stormwater Assessment

      This Allen Creek Stormwater Assessment (stormwater assessment) describes a range of potential structural stormwater retrofit projects recommended to improve water quality and reduce stormwater runoff in the Allen Creek watershed in Monroe County, New York. The projects presented in this stormwater assessment are based on a planning-level analysis and are recommended for further study prior to implementation. An overarching goal of this stormwater assessment is to help Monroe County and other municipalities in the county restore water quality to sustain designated uses as required by the federal Clean Water Act.
    • Food Habits of Irondequoit Bay Fish

      Ellis, Robert H. (1976-01-01)
      This report presents an evaluation of the potential impact of dredging a navigation channel connecting Irondequoit Bay and Lake Ontario on the fish populations of the area, based on a study of the food habits of the fish. Most fish are largely opportunistic feeders, subsisting largely on the most readily available and abundant food organisms. Yet there may be great differences in the food habits of species or fish inhabiting any given region. These differences result from differences in physical adaptations of a species, the size of the fish, and the particular habitat occupied, Species of fish of differing food habits may respond quite differently to the proposed dredging operations as the result of differing effects on the food organisms. The information in this report supplements that of our previous report concerning the potential environmental impact of the Irondequoit Bay dredging project (Ellis, Haines and Makarewicz, 1976).
    • Irondequoit Bay Fish Stock Assessments 2005-2015

      Sanderson, Matthew J.; NYS DEC (2018-09-13)
      Warm water fisheries assessments using standard gangs of gill nets were conducted in Irondequoit Bay in September of 2005, 2010, and 2015. In addition, a nighttime electrofishing survey was conducted in June 2009. The surveys were conducted to 1) assess the fish community; 2) determine the contribution of stocked fingerlings to the walleye (Sander vitreus) population; 3) estimate population characteristics of walleye, northern pike (Esox lucius), yellow perch (Perca flavescens), and largemouth bass (Micropterus salmoides), 4) compare fish community structure to statewide surveys; and 5) guide the development of appropriate management recommendations. From 2005 to 2015 overall gill net catch per unit effort (CPUE) increased and species dominance shifted from yellow perch to white perch (Morone americana). Walleye CPUE doubled, but the portion of legal sized fish declined during this time period. The walleye population is mainly sustained by stocked fingerlings, despite migratory spawning runs in Irondequoit Creek that could be producing fry that potentially recruit to adults. Survival and recruitment of the stocked fingerlings is good, but may be declining. Mean total lengths (TL) are above New York State (NYS) averages at all ages, and growth rates show an increasing trend. Mean TL of all walleyes declined from 2005 to 2015 because younger, smaller individuals, absent from the 2005 sample, were sampled in 2015. Walleye condition is near established standards. Even with declining survival, the fishing quality for Irondequoit Bay walleyes should be very good for several years. Northern pike relative abundance declined from 2005 to 2015. Most northern pike sampled during the period were legal size. Adult pike, while fast growing, are in below average condition in Irondequoit Bay. Yellow perch relative abundance in Irondequoit Bay remained nearly constant from 2005 to 2015. Survival of the 2004 to 2009 yellow perch year classes is generally very good. Growth and condition of yellow perch is good to fair, but showing a stable to slightly increasing trend. Competition with other species, namely very abundant white perch, may be a factor that explains fair yellow perch growth and condition in Irondequoit Bay. Yellow perch fishing in Irondequoit Bay has been outstanding in recent years. Relative abundance of white perch increased fourfold, while mean total length and relative weight declined from 2005 to 2015. This suggests that intraspecific competition due to high white perch abundance and interspecific competition with abundant yellow perch may hamper growth of both species. Rock bass (Ambloplites rupestris) and bluegill (Lepomis macrochirus) relative abundance in Irondequoit Bay appears to have been consistent, but low, from 2005 to 2015. Irondequoit Bay rock bass and bluegill exhibit good growth and are in good condition, which might be expected given the low abundance of these species. Largemouth bass relative abundance in Irondequoit Bay is average when compared to other New York State waters. The size quality is good, while growth and condition of largemouth bass is excellent in Irondequoit Bay. It is recommended that all current management actions be continued, walleye pond fingerlings be stocked every other year, the success of stocked walleye fingerlings be evaluated, and a fisheries management plan be developed for Irondequoit Bay.
    • Irondequoit Bay Monitoring Report 2015

      The Irondequoit Bay 2015 Monitoring Report continues 31 years of monitoring by the Monroe County Department of Environmental Services in partnership with the Monroe County Health Department. Monitoring is done using the Hach Surveyor 4a Hydrolab to gather water samples that are tested to determine the trophic state of the bay. The data are used to inform the watershed management program and improve the health of the bay.
    • Irondequoit Bay Monitoring Summary 2016-17

      Sansone, Andrew; Monroe County (2018-02-23)
      This is a brief summary of monitoring results for 2016 and 2017. The report focuses of phosphorus and chloride levels as well as hypolimnetic oxygen.
    • Irondequoit Bay Monroe County, New York

      Makarewicz, Joseph C.; Nowak, Matthew J.; The College at Brockport (2010-01-01)
      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 goals set by the county. Irondequoit Bay is located within the Rochester embayment, an indentation of the shoreline stretching from Bogus Point to Nine Mile Point. Much of the southern shore of Lake Ontario, the Bay, and the shoreline of Lake Ontario experience nuisance algae, bacteria, and algal mat development which foul the nearshore waters and limit water recreation. This short report provides a synopsis of data collected monthly from May through September (2003 to 2009) on the water quality of Irondequoit Bay and the lakeside (swimmable depth) of Lake Ontario near the mouth of the bay.
    • Irondequoit Bay Nutrient Levels and Trophic State

      Sansone, Andrew (2019-03-01)
      Long term trends show lower levels of phosphorus in the epilimnion for the past nine years. Determining the amount of phosphorus is important as high levels can result in excessive algae growth known as eutrophication. The successful effort to reduce the amount of wastewater entering the bay resulted in large phosphorus reductions. Watershed contributions from stormwater runoff as well as the loading from internal processes still have the potential to fuel eutrophication. In recent years the bay has met the long term goals for phosphorus concentration and has not experienced large algal blooms.
    • Pultneyville, Salmon Creek Wayne County, New York

      Makarewicz, Joseph C.; Nowak, Matthew J.; The College at Brockport (2010-01-01)
      Pultneyville is located between Irondequoit Bay and Sodus Bay, approximately 14 miles east of Irondequoit Bay and 12 miles west of Sodus Bay. Salmon Creek drains into Lake Ontario at Pultneyville where it forms Pultneyville Harbor that boasts a 100-boat marina as well as a yacht club. Agriculture, specifically fruit orchards, dominates the harbor watershed. Little background information is available for this location. Here we report on water quality data collected monthly (May through September) in 2007 and 2009 at Pultneyville Harbor and at lakeside location east of the harbor in Lake Ontario.
