TITLE: "The March of Hydrilla in Connecticut & Reclaiming the Connecticut River from Hydrilla"
Abstract: Hydrilla was discovered in Connecticut in 2008 in a pond near Mystic Seaport. In the following decades, it was observed in several other Connecticut lakes and the Silvermine River. This was the monecious strain typically seen from the Carolinas northward. In 2016, a new strain of Hydrilla was found in the Connecticut River with subsequent surveys documenting nearly 1000 acres from southern Massachusetts to within a few miles of Long Island Sound. Although both strains can cause serious ecological and economic damage, the Connecticut River strain is more robust and can rapidly engulf entire coves, marinas, and river systems. In 2022, Connecticut River Hydrilla was detected near a boat launch in East Twin Lake. At present, the strain has been confirmed in eight other lakes. This rapid spread is alarming. Mr. Greg Bugbee from the Connecticut Agricultural Experiment Station, and Dr. Ben Sperry from the United States Army Corps of Engineers, will discuss the history and biology of Hydrilla, how it is spreading in Connecticut, and the ongoing work on finding effective management options.

TITLE: "Five Years into Grants for the Control of Aquatic Invasive Species in CT"
With the passage of Public Act No. 19-190 in 2019, a grant program was formed to help in the management of aquatic invasive species and cyanobacteria blooms. Support for the program has been through the Aquatic Invasive Species Stamp funds collected and deposited into the "Connecticut Lakes, Rivers and Ponds Preservation Account." Matt Goclowski will discuss the grant program, some changes to the program on the horizon, and discuss the upcoming request for proposals for 2025 projects. This is your chance to begin planning your grant application!
Neil Stalter, Candlewood Lake Authority, Director of Ecology and Environmental Education
TITLE: "Discussion by Lake and River Community Stakeholders on Their Projects Funded Through the Connecticut Lakes, Rivers and Ponds Preservation Account"
ABSTRACT: The Candlewood Lake Stewardship Program had been funded for the last four years through the AIS Grant Program. In that time, lake stewards have performed over 2,500 voluntary boat inspections for aquatic invasives, have stopped six instances of new potential invaders, have collected anonymous recreational data, and have performed boater education.
Jeff Arpin and Al Fichtel Amston Lake District
TITLE: "Thwarting the Spread of Eurasian Watermilfoil at Amston Lake in Hebron, Lebanon and Colchester, Connecticut"
The Amston Lake Tax District (ALTD) was created in 2002 by a special act of the Connecticut General Assembly. The ALTD is managed by a municipal government run by a nine-member board of directors whose mission statement is to promote lake health and resident safety. They are elected to oversee lake management, environmental monitoring, and neighborhood security. There are over 800 property owners in the Amston Lake District.
Amston Lake had a very diverse aquatic plant flora and never had an aquatic invasive plant until 2021. Hear from current and past ALTD members on how planning and quick response averted the spread of Eurasian watermilfoil at this lake.

TITLE: "Putting the RAPID in Rapid Response: Considerations for Effective Reaction to Aquatic Invasive Species"
Abstract: Preventing the infestation of lakes by aquatic invasive species (AIS) is far preferable to conducting extensive eradication or maintenance programs in terms of success, unintended impacts, and cost. As AIS use multiple means of dispersion that can be difficult to control, rapid response plans (RRP) represent an important defense, allowing removal before an infestation can reach the stage where eradication becomes difficult to impossible. Key elements of a RRP include:
- Detection of Invasion – Monitoring to ensure that invasions are detected early
- Quantifying the Extent of Invasion – More monitoring to determine how much area is affected
- Species Threat Summary – Analysis of total area that could be affected and what impacts are likely
- Communication and Education – Getting the word out to all involved or affected parties so that cooperative action can be taken
- Quarantine Options – Determining what actions to take to prevent further spread
- Control of Infestations – Any of multiple actions to eliminate the AIS, often species-specific
- Prevention of Re-Infestation – Closing off routes of invasion if known and manageable
Each step presents opportunities and challenges, particularly with regard to mustering resources and getting necessary approvals (permits) to take action. Examples from around southern New England suggest that current state permitting and management systems are woefully inadequate for supporting rapid response. Local groups (towns, lake associations) would be well served by putting a RRP in place and seeking all approvals in advance of necessary implementation. Putting the “rapid” in rapid response is probably the most important thing on which to focus.

Joe Cassone, Fisheries Biologist, CT DEEP
TITLE: CT DEEP Update on Candlewood Lake Grass Carp and Aquatic Vegetation Management Efforts
ABSTRACT: Following the drastic decline in aquatic vegetation coverage at Candlewood Lake in 2022, CT DEEP investigated the potential causes of the decline and courses of action to restore a balanced vegetation community. Excess grazing pressure by grass carp was identified as the primary cause; in response a grass carp population reduction effort was initiated in May 2023. From May-September 2023 CT DEEP removed 219 grass carp from Candlewood Lake. The goal of the removals is to allow for a partial recovery of vegetation without a return to nuisance levels. Future efforts will consist of continued removals, vegetation monitoring, and working with partners to develop a more robust network of vegetation exclosure areas, and informed lake management objectives.
Neil Stalter, Candlewood Lake Authority, Director of Ecology and Environmental Education.
TITLE: The Ecology Behind Candlewood Lake's Rapid Plant Loss
ABSTRACT: Candlewood Lake Authority Director of Ecology Neil Stalter will go into the ecological phenomena that can explain how multiple factors, including the sterile grass carp, drawdown, and others contributed to the dramatic change in Candlewood's Plant Community. Learn how the ecological theory of Alternative Stable States can shed light on how Candlewood's ecosystem changed so quickly, and how it can inform management to help return the ecosystem to a healthy plant balance in the future.
William Henley, Sr. Aquatic Resource Scientist, South Central Connecticut Regional Water Authority.
TITLE: Remote Turbidity Monitoring & Selective Diversion for Improvement of a Drinking Water Lake
ABSTRACT: The South Central Connecticut Regional Water Authority (RWA) is a public drinking water supplier with ten active reservoirs. Its Lake Saltonstall system consists of two waterbodies; Furnace Pond (30 acres) & Lake Saltonstall (430 acres), which are hydrologically connected, and a diversion impoundment located on Farm River. Due to the small watershed to lake ratio of Lake Saltonstall and the desire to avoid excessive drawdown of this natural waterbody, supplemental diversion is required from the Farm River to maintain the lake’s water level. As the Farm River watershed contains a substantial proportion of agricultural and urban land uses, the RWA has implemented a remote turbidity monitoring station to guide water diversion operations. This remote monitoring program has allowed for improved operation of the Farm River diversion, reducing nutrient influxes, avoiding first flush precipitation events. The data collected from this initiative has also lead to increased understanding of the dynamic Farm River watershed.
Connie Trolle, President of the Bantam Lake Protective Association.
TITLE: A Conversation About Wakeboards and Shoreline Management
Connie Trolle is the President of the Bantam Lake Protective Association and the first woman to hold this position since the founding in 1925. In this role, she created a coalition fund to manage invasive weeds and storm water issues at Bantam Lake. She is also the Past-President of the Connecticut Federation of Lakes and instrumental in pushing forward the legislation that created legislation that will create a grant program for aquatic invasive species and cyanobacteria related projects. She is also served as a Commissioner of the Inland Wetland, Town of Morris; Chairman of the Board of Finance for the Town of Morris, and President of the Bantam Lake Task Force. Connie has lived on Bantam Lake as a summer resident all her life. She lives on the lake full time and is very active in the community.
