On Tuesday, the forecast model for the lake level showed it would reach 100.7 feet by 1 a.m. Friday.
Day said there could be some shoreline damage when the lake reaches 100 feet, but probably not major flooding unless it gets to at least 101 or 102 feet.
In 2011, the lake reached more than 103 feet and serious damage resulted in several communities with flooding that lasted for weeks.
“Hopefully, it won’t get that far this year,” Day said.
Six side roads in Essex County were flooded and closed to traffic on Tuesday.
In Elizabethtown, four roads were blocked by the county due to flooding: Gilligan, Kingdom Dam, Otis and Scriver lanes. These roads are intersected by the Boquet River.
In Keene, Hulls Falls Road was closed due to high water on the East Branch of the Ausable River.
The Gulf Brook behind the closed and now empty former Keene Fire Department was raging, but it was not threatening new flood walls built last year to shore up damage from Tropical Storm Irene.
And in North Elba, near the Lake Placid village line, the River Road was closed from Route 73 to 86 due to inundation on the West Branch of the AuSable River.
Minor flooding along sections Lake Flower Avenue was being reported in the Village of Saranac Lake.
“It’s minor flooding so far,” Essex County Emergency Services Director Donald Jaquish said Tuesday afternoon, “no evacuations, no major problems so far.”
At 2 p.m., Provost was fresh from a conversation with the National Weather Service in Burlington, which advised him that heavy rain would continue until about 7 or 8 p.m. then turn to snow showers that would dump a few inches on the region before midnight.
But until then, “they told us to expect another half-inch of rain before dark,” the director said.
