Cutting Road Salt On Adirondack Roads

Plow-600x382Standing next to a small, unnamed stream near where it empties into Mountain Pond on a cool September day, scientist Dan Kelting reads a sensor he just dipped in the water to measure electrical conductivity, which is used to gauge road-salt concentrations.

Pure water is a poor conductor of electricity, but road salt, or sodium chloride, increases conductivity. Based on the conductivity reading (285 microsiemens per centimeter), Kelting calculates that the water contains 80 milligrams of chloride per liter. This means the stream contains roughly 160 times more chloride than a similar size stream a few miles away.

Why the difference? The stream near Mountain Pond, north of Paul Smith’s College, is downstream from Route 30, a state highway that is heavily salted in the winter. The other stream, which Kelting refers to as Smitty Brook, runs through the Forest Preserve and is upstream of roads. » Continue Reading.

Programs Combating Invasives on Boats Expand

Boaters on Adirondack waterways will be a lot more likely to be questioned about whether they are transporting invasive species at local boat launches this year thanks to a boost in funding for two water steward programs. The Watershed Stewardship Program at Paul Smith’s College will nearly quadruple its workforce across the central Adirondacks this year while the Lake George Association is also expanding its coverage at Lake George.

With the help of a grant from the U.S. Fish & Wildlife Service’s Great Lakes Restoration Initiative, Paul Smith’s stewards will help protect three major recreational areas: Saratoga Lake; the Lake Placid, Saranac Lake and Tupper Lake region; and the Fulton Chain of Lakes in the Old Forge area. The Lake George Association’s Lake Steward Program on Lake George will also significantly expand over last year’s level thanks to new funding provided by the Lake George Park Commission. » Continue Reading.
