Canandaigua Lake Harmful Algae Bloom Forum
Tuesday, November 13th at 6:30 PM 
Canandaigua Middle School AuditoriumBGA_9_18_Greg Talomie

This summer, Canandaigua Lake experienced an unprecedented Harmful Algae Bloom event that impacted our use and enjoyment of the lake. For the first time ever, detectable levels of toxins were found in the drinking water supply of a community drawing water from Canandaigua Lake.

Please join us for this important community forum with leading experts to discuss results from 2018 monitoring efforts, the factors that influence algal blooms, and the local and Statewide efforts to protect our water resources.

Local data will be presented by the Canandaigua Lake Watershed Council and CLWA.

Speakers will include:

Kevin Olvany, CPESC CPSWQ
Watershed Program Manager, Canandaigua Lake Watershed Council
“Local HAB trends and Monitoring Efforts”

Rebecca M. Gorney, PhD
Research Scientist, Division of Water
Lake Monitoring & Assessment Section, NYS DEC
“NYS DEC HABs Program: Results from 2018”

Anthony R. Prestigiacomo
Research Scientist, Division of Water
Finger Lakes Watershed Hub, NYS DEC
“HABs in Low Nutrient Lakes: Mechanisms, Knowledge Gaps, and Moving Forward”

Lloyd R. Wilson, PhD
Director of Drinking Water Program for NYS
Bureau of Water Supply Protection, NYS Department of Health
“HABs and Drinking Water”

A Q& A session to follow with presenters. We hope you will join us!

Past Events

CLWA Annual Meeting
Wednesday, August 15th
6:00-8:00 PM
Finger Lakes Community College Stage 14

The Annual Meeting is a great place to hear more about current watershed initiatives! Join us for a business meeting with officer elections, bylaw updates, reports from the Chair and Treasurer, and award recognitions including the announcement of our 2018 Photo Contest winners. Kevin Olvany, Watershed Program Manager (Canandaigua Lake Watershed Council) will deliver the evening’s keynote presentation, sharing information on the current water quality status of the lake and highlighting local programs and projects aimed at addressing watershed threats. State Senator Pam Helming will also join us to share her perspective on the New York State programs focused on water quality issues. We hope to see you there!


Viewpoints Event: Protecting our Vital Watershed Birds
Thursday, May 10th 2018 6:30 PM
FLCC Stage 14 

The National Audubon Society protects birds and the places they need, today and tomorrow, throughout the Americas using science, advocacy, education, and on-the-ground conservation. Audubon’s state programs, nature centers, chapters, and partners have an unparalleled wingspan that reaches millions of people each year to inform, inspire, and unite diverse communities in conservation action. Since 1905, Audubon’s vision has been a world in which people and wildlife thrive. Chris Lajewski, Center Director of the Montezuma Audubon Center, highlighted the birds of conservation priority within the Canandaigua Lake Watershed and how you can help protect them.


VIEWPOINTS EVENT: Finger Lakes Mercury Project, Focus on Canandaigua Lake 
Tuesday, Marc 6th 2018 
FLCC Stage 14 mercury flyer2

Mercury is a global pollutant that impacts communities at the local level. The Finger Lakes Mercury Project was initiated in 2015 by the Finger Lakes Institute in collaboration with Finger Lakes Community College, to assess the extent of mercury contamination in Finger Lakes aquatic food webs. Findings were presented for Canandaigua Lake zooplankton, benthos and fish, stream macroinvertebrates and fish, and placed in the context of trends observed for other Finger Lakes.

Presented by: Roxanne Razavi (PhD, Queen’s University, 2014; ecotoxicology, limnology, environmental toxicology, mercury) Roxanne is an Assistant Professor in SUNY ESF’s Department of Environmental and Forest Biology.


Tuesday, January 23rd at 6:00 PM
South Bristol Town Hall

CLWA hosted a landowner workshop on the impacts of the Hemlock Woolly Adelgid (HWA), an invasive forest insect that is threatening our region’s hemlock trees.

Cover_HWA_Whitmore_highres_horizHWA has been found throughout the Canandaigua Lake watershed and tree mortality typically occurs 6-10 years after infestation. Landowners are encouraged to attend a workshop on Tuesday, January 23rd at 6:00 PM at the South Bristol Town Hall to learn more about the threat, and how to identify and manage HWA on their own property.

The workshop, led by Charlotte Malmborg of the New York State Hemlock Initiative, will feature information on the identification of hemlock trees and HWA, management strategies for landowners, and key information on the history and fate of HWA across the region. The NYS Hemlock Initiative’s new Biocontrol Research Lab on the Cornell Campus will also be discussed. A licensed pesticide applicator will be on hand to answer questions about the various treatment options available to landowners.

Eastern hemlocks occupy a unique position in our Finger Lakes forests. Because they are so shade tolerant, they grow in the shady gullies where other trees can’t. Their cover and root systems help to reduce both erosion and the temperature for the streams running to Canandaigua Lake. Hemlocks are the “cornerstone” of a unique ecological community of plants, such as ferns and mosses, and animals, such as salamanders and brook trout that are increasingly rare in urbanized areas. CLWA is very concerned about the potential loss of hemlocks in the lake’s gullies that could lead to increased erosion and nutrient losses.

Phosphorus: Forms, Bioavailability, and Importance
Presented by: Tony Prestigiacomo
Tony is a Research Scientist with the DEC’s Finger Lakes Watershed Hub who’s interests include water quality monitoring, nutrient loading, and the interactions between lakes and streams.

Blue Green Algae Blooms: Is Phosphorous Responsible? Phosphorus is often described as the nutrient that limits primary production in temperate freshwater ecosystems. However, phosphorus exists in multiple forms and not all forms are equally useable by algae and phytoplankton for growth. Understanding common types of phosphorus and their relative availability to primary producers can be important knowledge for management of watersheds and lake water quality.
