Garnet Lake- Aquatic Invasive Plant Monitoring 2021
Garnet Lake participates in the Adirondack Park Invasive Plant Program(APIPP) andspecifically with respect to aquatic invasive plants. There are workshops eachyear which provide updates and identification techniques for lake stewards. Judy andSteveThomson usually attend this program but were unable to do so this year. Aquaticinvasive plants have not been found in the waters of Garnet Lake to date. We continueto be in early detection mode at the present time. Since resources to systematicallycheck boats entering and leaving the lake is largely impractical froma financial andmanpower perspective, early detection is the way for us to avoid the costly control andmanagement consequences if aquatic invasives were to be found in the lake.
What we do: We do regular monitoring of the lake, essentially in water that is 6feet or less, in weed beds around the lake. APIPP asks each volunteer responsible for lakeaquatic invasive species (AIS) to survey the lake at least once between the middleof July and September. We actually have surveyed the lake up to four times in this timeperiod in previous years. (Roy and Sue Keats and Judy Thomson have assistedmeinthis effort). We then submit a report to APIPP informing them of our activities andour findings. We surveyed the lake on July 27 this year and plan a follow up survey inAugust on a clear, calm day. As we paddle the lake frequently, we survey unofficiallyaswell. Surveys like ours have been done on over 400 Adirondack lakes and AIShavebeen found in about 25%of those surveyed. So the good news is that 3 out of 4of thesurveyed lakes are so far free of aquatic invasive species and we are in that group.
There are local lakes which have AIS (Loon, Minerva, Lake George, Hadlock Pond, andmore). Their associations or municipalities have invested considerable resourcestocontrol the spread of invasives in their waters. In many cases that total eradicationhasnot been accomplished, the investment in managing AIS continues. The economicandenvironmental consequences of dealing with this problem are serious. Preventionandearly detection are the best ways to avoid these negative consequences.
Potential Threats: Since boats and trailers are the main vectors for the introductionof aquatic invasive species into a lake, we need to be concerned since we have apublicboat launch on the lake. We do not have the volunteer capacity, or financial resourcesto staff a checkpoint for boats leaving or entering the lake. Outside resources arelimitedand are utilized for the larger and higher priority lakes in the Park. While boat washingstations and launch checkpoints are used at some, resources for lakes such as Garnet are generally not available. There is DEC signage at the Garnet Lake launch sitewhichclearly emphasizes to boaters that regular “clean, drain, and dry” methods are recommended to keep boats free of aquatic invasive species. DEC installed a barrier in2018 which prevents trailers from entering the lake to launch watercraft. This ineffect limits the size of boats that can enter the lake from the public site. This year as aresult of the COVID-19 Pandemic, there has been considerably more boat traffic throughthelaunch site and day use sites along the east side of the lake. Thus there is an increasein the likelihood that some boats may bring in invasives. Vigilance is important.
Our lake is shallow, warms more quickly than most lakes, and has a lake bed that isrichin organic matter. These conditions are ideal for plant growth. Currently we haveahealthy diversity of native water plants but aquatic invasive species can overtakethisbalance if we are not actively working to keep them out.
