Diamond Lake residents are fortunate to live on a beautiful lake with high water quality and be a step ahead of the invasive weed issues that have plagued other lakes in the Great Lakes Region. Maintaining Diamond Lake water quality is a collective effort, starting with citizen volunteers for the Collective Lakes Monitoring Program (CLMP).
…that the body of water commonly known as Lake George has an approximate area of 28,200 acres, an elevation of 322 feet, a maximum depth of over 200 feet, a length of 32 miles, a maximum width of almost 4 miles, about 44 square miles of surface area, almost 20% of its water from underground springs, and a surprising 8 years to exchange its volume of water.

Sturgeon are prehistoric looking creatures that have been around since before the dinosaurs. Unique in appearance, sturgeon look somewhat sharklike with large submarine-like bodies and strongly upturned heterocercal (top is two to three times longer than bottom) tails. They have flattened prominent snouts with underslung mouths and barbels (whiskers). Instead of scales, five rows of large bony plates or shields (called scutes) cover the sturgeon's leatherlike skin. The scutes provide protection against predators and add to the fish's primitive appearance. Toothless, sturgeons are bottom feeders. They drag their barbels along the bottom to locate food and then extend their tubular mouth to suck it up. Any silt, gravel, or other bottom materials also taken in is expelled through the gills. The food is then ground by their muscular gizzard-like stomachs. Sturgeon are extremely long-lived, living to 60 plus years old. They are slow to mature and generally do not spawn for the first time...
Sturgeon belong to one of the most primitive groups of bony fishes. They're a relict species, having survived since the Mesozoic era, 65-230 million years ago. While some characteristics have changed over time, sturgeon remain basically the same as they have been since their beginning. Today's sturgeon have a mostly cartilaginous skeletal system, a sharklike tail fin (called heterocercal) which has the upper lobe longer than the lower lobe, and fine horny fin rays. These characteristics are known from fishes present during the Devonian period, which occurred 360-408 million years ago. Sturgeon also have a notocord, the precursor to the bony vertebral column found in most other "advanced" fish species. The bony scutes covering their bodies are remnants of primitive ganoid scales, scales that have an outer enamel layer made up of a distinct substance called ganoine. The order to which sturgeon belong (Acipenseriformes) includes an extinct fossil family that dates from the Lower Jurass...
Few freshwater fish species have had such a yo-yo relationship with man. Eastern Forest Indian tribes worshipped these huge fish, admiring them for their remarkable size and strength, and relying on the annual harvest of their meat and skins for sustenance. During colonial times, most people considered sturgeon a nuisance and trash fish. Certain accounts state that sturgeon were so plentiful they actually clogged rivers during their spawning runs. Large sturgeon that were caught accidentally by fishermen were either discarded, fed to pigs, used as fuel to power steamboats, or used for fertilizer. Hudson River sturgeon were so common that caviar was given away. Beginning in the mid to late 1800s, North Americans became aware of the value of sturgeon. Europeans considered caviar a delicacy and so the demand for sturgeon exploded. In addition to caviar, sturgeon were harvested for a number of purposes: sturgeon meat was delicious, especially smoked; the skin was tanned for leather; and...
Many species of fish look alike, making it difficult to tell them apart. In addition, many types of fish have different common names in different parts of the country. To distinguish one organism from another, biologists give each a scientific name that is unique to that organism. The names are derived from the Latin language and consist of a genus and a species. The genus name is first and is capitalized. The species is second and is in lower case. Both the genus and species are either underlined or italicized when written. While several organisms in the same "family" share a common genus name (like family members sharing a last name), they have different species names. Occasionally, two members of a family are so similar that one is considered a subspecies of the other. In these cases, the organisms are given two species names. Here are the common and scientific names of New York State's sturgeon:

Water chestnut has been found in more than 40 counties in New York State. For a map of where water chestnut has been documents, please visit iMapInvasives' interactive mapper (leaves DEC website).
Water chestnut is an annual plant with a submerged stem 12-15 feet long that has fine roots that anchor it to the soil. Its floating leaves are triangular in shape with saw-toothed edges and hollow air-filled stems. Leaves form a rosette around a central point. Its tiny flowers generally bloom in June and are four-petaled and white. Each rosette can produce up to 20 hard nut with four-inch spines that have barbs along them. Seeds within fruits can remain viable for up to 12 years.
Water chestnut spreads by rosette and fruits detaching from the stem and floating to another area. They also spread by clinging to floating objects including recreational watercraft, the pads of boat trailers, and fishing equipment.
Water chestnuts form dense mats of rooted vegetation that can be very difficult to get through in a boat, kayak, canoe, or when swimming. Water chestnut fruits are often found along the shoreline and bottom of waterways - they have very sharp spines with barbs that can cause painful wounds when stepped on. The dense mats of vegetation shade out native aquatic plants that provide food and shelter to native fish, waterfowl, and insects. Decomposition of these dense mats reduces dissolved oxygen levels and may kill fish. Property values along shorelines of infested waters may also decrease.
Prevention is the most effective method for dealing with invasive species. If they are never introduced, they never become established. 1. Clean, drain, and dry your watercraft, trailer, and equipment before and after each use. Regulation 6 NYCRR Part 576 requires everyone who uses watercraft on public waters to, when possible, use the following methods to fully decontaminate your equipment: 1.1. Clean the outside of the watercraft and trailer with high pressure (2500 psi) hot water (140°F) for 10 seconds. 1.2. Flush the inside of the motor and all compartments (bilge, live well, bait buckets, ballast, etc.) with hot water (140°F) for two minutes. 1.3. Soak fishing gear and equipment in hot water (140°F) for two minutes. 2. Dump bait bucket water where it came from or on land. 3. View more information on how to clean your boat. Early detection of infestations helps to reduce removal costs and ecological impacts. 1. If you think you've found water chestnut please take several photos...
Water chestnut can be controlled using manual, mechanical, and chemical methods. As with all other infestations, early detection is key for containing and controlling spread. DEC is currently funding research on biocontrol - a study of the effectiveness of predator insects from water chestnut's native range - in controlling the spread of water chestnut. The smaller the size of the infestation, the more easily it can be eradicated, and its economic and ecological impacts reduced. Because water chestnut is an annual plant, effective control can be achieved if seed formation is prevented. A site may be a candidate for eradication(eliminating the plant from the area entirely) if: 1. small in size (trace-sparse density), 2. detected and treated early (no significant seed bank has been established), 3. located within an isolated body of water, or is an isolated population within a larger body of water (unlikely to be re-infested), 4. clean, drain, dry participation prevents new introducti...

The most widespread and frequently encountered snakes in New York state are the garter snake and the water snake. Garter snakes use a wide variety of habitats, from woodlands to marshes to fields and exist quite well around human habitations. These snakes, like many other species, are variable in color and pattern; the basic color is dark brown ...
