"Perhaps no other lake-related issue causes as much heated discussion as chemical controls. At many lake association meeting, large or small, there will likely be two factions, both convinced that the other could ruin the lake. One faction may claim that there are absolutely no conditions or situations that call for chemical treatments. The other group may insist that if herbicides are not applied immediately, weeds will take over the entire lake, destroying recreational use and slicing property values. And neither group is likely to listen to the other..."-NYSDEC

Impact Assessment:"Any activity that would substantially degrade water quality, increase temperature or turbidity, alter water depths, or reduce flows, would adversely affect the fish and wildlife along the Carmans River. The alewife would be especially sensitive during spawning (April - July_ and the sea-run brown trout would be especially sensitive during their fall spawning period (september - November) ... other polutants (including septic leachate, herbicides, and fertilizers) may also result in adverse impacts on the Carmans River fish and wildlife habitat. .."-Coastal Fish & Wildlife Habitat Rating Form

Cost-Benefit Analysis:"An externality occurs when either a positive or negative effect on an outside party results from a market transaction. An example of a positive externality is the creation of an outstanding trout fishery downstream of a major reservoir in the western U.S. resulting from the release of cooler, clearer water from the outlet works. A negative externality may result from dam removal if upstream landowners are left with a barren, dry lake bottom rather than an attractive riparian shoreline. These effects, whether positive or negative, must be accounted for in determining the full cost of dam removal and river restoration. Moreover, they are important to understand as interest groups such as trout fisherman or riparian landowners will likely mobilize around these externalities to either support or oppose dam removal..."Read More...
