Red coloring represents waterbodies with reported bloom and not spatial extent. 3 Landsat 8 Owasco Lake Bloom 9/20/2016 Near shore monitoring could miss the off shore bloom.

It supersedes Geological Survey Circular 504. Basic data on surface-water supply have been published in an annual series of water-supply papers consisting of several volumes, including one each for the States of Alaska and Hawaii. The area of the other 48 States is divided into 14 parts whose boundaries coincide with cenain natural drainage lines. Prior to 1951, the records for t'le 48 States were published in 14 volumes, one for each of the parts. From 1951 to 1960, the records for the 48 States were published annually in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6.

    HARMFUL ALGAL BLOOM ACTION PLAN HONEOYE LAKE Photo Credit: Terry Gronwall www.dec.ny.gov EXECUTIVE SUMMARY SAFEGUARDING NEW YORK’S WATER Protecting water quality is essential to healthy, vibrant communities, clean drinking water, and an array of recreational uses that benefit our local and regional economies. 200 NY Waterbodies with HABs Governor Cuomo recognizes that investments in water quality 175 protection are critical to the future of our communities and the state. 150 Under his direction, New York has launched an aggressive effort to protect state waters, including the landmark $2.5 billion Clean 125 Water Infrastructure Act of 2017, and a first-of-its-kind, comprehensive 100 initiative to reduce the frequency of harmful algal blooms (HABs). 75 New York recognizes the threat HABs pose to our drinking water, 50 outdoor recreation, fish and animals, and human health. In 2017, more 25 than 100 beaches were closed for at least part of the summer due to 0 HABs, and some lakes that serve as the primary drinking water source for their communities were threatened by HABs for the first time. 2012 2013 2014 2015 2016 2017 GOVERNOR CUOMO’S FOUR-POINT HARMFUL ALGAL BLOOM INITIATIVE In his 2018 State of the State address, Governor Cuomo announced FOUR-POINT INITIATIVE a $65 million, four-point initiative to aggressively combat HABs in Upstate New York, with the goal to identify contributing factors fueling PRIORITY LAKE IDENTIFICATION Identify 12 priority waterbodies that HABs, and implement innovative strategies to address their causes 1 represent a wide range of conditions and protect water quality.

Chapter 2 – Tributary Research Methods . Results and Discussion . Recommendations and Topics for Future Research . Literature Cited . 2 Executive Summary: 1. Over the last three years, the health of Canandaigua Lake remained good to excellent. Dissolved oxygen was available throughout the water column at all monitoring times and often was at or near 100% saturation, ideal conditions for the survival of aquatic life. Seasonal temperature profiles characterized the development of thermal stratification typical of deep lakes. The pH was always above 7.00 (due to high buffer capacity of lake water), helping to protect the lake from the damaging effects of acidic precipitation storm events. Conductivity, a measure of ions dissolved in the water, averaged between 350 and 400 μS/cm. Recent increases in conductivity may stem from watershed development activities. Total phosphorus, the critical nutrient governing lake productivity and the element most responsible for lake eutrophication, was often below 10 μg/L during the monthly sample periods. Algal productivity, estimated by the concentration of chlorophyll a, ranged from 0.62 to 9.48 μg/L with a mean of 2.41 μg/L.

Prestigiacomo or (585) 394-5030. Research Scientist, DEC Division of Water, Finger Lakes Watershed Hub Canandaigua Lake is a historically low nutrient lake that has, since 2015, documented shoreline accumulations of cyanobacteria and, recently, experienced large-scale, open water cyanobacterial blooms in the northern portion. At this talk, Tony will describe his summer research project on Canandaigua Lake, which is designed to collect detailed temporal (in time), vertical (in depth), and spatial data at multiple locations at both open-water and nearshore sites for field parameters, user perception, trophic state indicators (nutrients, chlorophyll-a, and clarity), in-situ chlorophyll-a and phycocyanin concentrations, and microcystin toxins. The information collected will be used to: (1) collect scientifically defensible data sets to help understand the formation and distribution of cyanobacteria biomass and microcystins in low nutrient lakes, and (2) determine the representativeness of the open water, long-term monitoring location compared to intensively monitoring, additional sites from this study.

  • 2016 Finger Lake Water Quality Update Report
    WATER QUALITY OF THE EIGHT EASTERN FINGER LAKES, NEW YORK: 2005 – 2016. John D. Halfman Department of Geoscience, Environmental Studies Program & Finger Lakes Institute Hobart and William Smith Colleges Geneva, NY 14456 [email protected] 12/31/2016 EXECUTIVE SUMMARY The eleven Finger Lakes of western and central New York are critical to the health, well- being and economy of the region. The range in trophic status, size, water residence times, bedrock geology, land use characteristics, and other features revealed by the FLs present an ideal natural laboratory to investigate a wide range of water quality issues, many pertinent to the Great Lakes. Professor John Halfman, Hobart and William Smith Colleges has maintained a water quality monitoring program of the eight eastern Finger Lakes for the Finger Lakes Institute since 2005 (Honeoye, Canandaigua, Keuka, Seneca, Cayuga, Owasco, Skaneateles, & Otisco). The program collected and analyzed monthly CTD profiles, plankton tows, Secchi disk depths, most recently, (2016) fluoroprobe profiles, and surface and bottom water samples for nutrient (TP, SRP, NO3, Si), chlorophyll-a, total suspended solids, and major ion analyses back in the laboratory at a minimum of two mid-lake, deep-water sites in each lake. Selected stream analyses and two autonomous water quality and meteorological monitoring buoys deployed in the Seneca and Owasco watersheds provide additional data to better understand the limnology and water quality issues in these lakes. Relative ranks of the surface water data indicated that Skaneateles, Canandaigua and Keuka Lakes have the best water quality (ultra-oligotrophic to oligotrophic), Honeoye and Otisco Lakes have the worst water quality (eutrophic to borderline mesotrophic-eutrophic), and Seneca, Cayuga and Owasco Lakes were in between these end-members (borderline oligotrophic-mesotrophic to mesotrophic).

  • Trip a GLACIAL GEOLOGY of the WESTERN FINGER LAKES
    A-I Trip A GLACIAL GEOLOGY OF THE WESTERN FINGER LAKES REGION Victor E. Schmidt State University College at Brockport Note: This trip and discussion are designed primarily for undergraduate students, rather than for specialists in glacial geology __ who are, nonetheless, most welcome. An attempt, however imperfect, is made to distinguish observations from inferences, hypotheses, and specula­ tions based on these and other observations. The number of proposed stops is probably greater than time will allow, and so selection will be made on the basis of weather conditions and the interests of the group. Route: Leave Rochester, 8:00 AM. Take Rt ISA south, through Henrietta, Rush, and Lima, to Hemlock. At Rush, Rt lSA crosses westward-flowing Honeoye Creek, carrying water from three of the western Finger Lakes to the Genesee River, which flows northward to Lake Ontario. At Sibleyville, 1.3 mi from Rush, the route crosses a broad, swampy, flat-bottomed valley, interpreted as a glacial drainage channel which carried a river of glacial meltwater eastward, along the front of the glacier. (If time permits, a slight de­ tour via Phelps Rd and Wagner Rd will allow a better view.) Directly west of Honeoye Falls, 3.6 mi from Rush, is an outcrop of Middle Devonian Onondaga limestone, the formation over which Honeoye Creek falls at Honeoye Falls. Long, streamlined hills--typical drumlins--parallel the route; the road goes over several, and a large one can be seen to the west, from approx 4 mi south of Lima. South of Hemlock, leave Rt lSA and take Rt 20A east.
