LAKE ONTARIO MOST THREATENED GREAT LAKE,
FOLLOWED BY LAKE ERIE, NEW REPORT SAYS
planetsave.com/...
Formation and history:
Like all of the Great Lakes, Lake Ontario as it is known today was the result of glacial shifting and melting at the end of the most recent Ice Age.
While the entire region is affected by lake-effect snow, there is a prominent snow belt along the southeastern shore that can be deluged with 20 feet (600 centimeters) of snow annually. The impact of the lake-effect snow can be felt as far as Syracuse, N.Y., which is one of the snowiest cities in the United States.
(The lake's name comes from an Iroquois word for "a beautiful lake."
The first European to see reach Lake Ontario was Étienne Brulé, the French explorer and protégé of Samuel de Champlain. Brûlé is believed to have reached Lake Huron and Lake Ontario around 1615, according to the Canadian Museum of History. )

2017:
E.coli at worst-ever levels in Lake Ontario

Lake Ontario water temperature
Because of the lake's depth and the warm weather that comes in from the southwest, Lake Ontario rarely freezes over. Water temperatures reach a high of about 75 degrees Fahrenheit (24 degrees Celsius) in August to a low of about 37 F (3 C) in February. The lake typically freezes just around the edges, closing its harbors from mid-December to mid-April, according to Encyclopedia Britannica
Flooding:
Nov 9, 2017 · Hearing on Lake Ontario flooding draws a crowd. After a spring and summer of flooding and erosion along the Lake Ontario shoreline, water levels have subsided to near-normal levels. But concern about this year's flooding and the possibility it could occur again soon remains high

U.S. Precipitation Change(2014)
Since 1900, average annual precipitation over the U.S. has increased by roughly 5%. This increase reflects, in part, the major droughts of the 1930s and 1950s, which made the early half of the record drier. There are important regional differences. For instance, precipitation since 1991 (relative to 1901-1960) increased the most in the Northeast (8%), Midwest (9%), and southern Great Plains (8%), while much of the Southeast and Southwest had a mix of areas of increases and decreases.nca2014.globalchange.gov/...
The projected changes in the northern U.S. are a consequence of both a warmer atmosphere (which can hold more moisture than a colder one) and associated changes in large-scale weather patterns (which affect where precipitation occurs). The projected reduction in Southwest precipitation is a result of changes in large-scale weather patterns, including the northward expansion of the belt of high pressure in the subtropics, which suppresses rainfall. Recent improvements in understanding these mechanisms of change increase confidence in these projections.Held, I. M., and B. J. Soden, 2006: Robust responses of the hydrological cycle to global warming. Journal of Climate, 19, 5686-5699, doi:10.1175/jcli3990.1. URL | Detail
The Great Lakes have been facing growing numbers and levels of threats to their ecosystems and to the human-use of their resources in recent years. Large-scale toxic blue-green algae blooms, high-levels of mercury and PCB pollution, invasive species, etc, have been doing significant damage to the lakes. A newly released report by the Great Lakes Environmental Assessment and Mapping Project has detailed these problems and found that Lake Ontario is currently the most-threatened of the five Great Lakes, followed closely by Lake Erie.planetsave.com/...

Increased evaporation will result in more storms, but also contribute to drying over some land areas. As a result, storm- affected areas are likely to experience increases in precipitation- NASA
