Clark Reservation State Park

While Green Lakes State Park gets all the attention in the Greater Syracuse Area, you should also check out Clark Reservation in Jamesville. It's a very nice park, and in many ways much more wild and rugged then Green Lakes State Park.

"Clark Reservation State Park is a geologic wonder of the last ice age and a botanist's paradise. The park's natural features include rugged cliffs and rocky outcrops, woodland and meadow, a wetland and a glacial plunge basin lake in which the surface waters and bottom waters do not mix. Fishermen can catch pickerel, bullheads and sunfish; while birdwatchers may observe cedar waxwings, kingfishers and woodpeckers."

Onondaga Lake mystery: Why doesn’t it get toxic algae blooms?

"Onondaga Lake is very interesting," said Greg Boyer, who runs the SUNY College of Environmental Science and Forestry algae testing lab. "We've been monitoring it since 1985, and we have one example of a toxic microcystin bloom in all the samples we have collected. Oneida Lake during about the same time period has been toxic every single year."

"Boyer speculates that the water chemistry in Onondaga Lake, particularly the amount of phosphorus and nitrogen, helps inhibit toxic algae growth. The lake's chemistry is largely driven by Onondaga County's wastewater treatment plant, through which about 20 percent of lake's input flows."
