The Haines Borough Assembly Tuesday voted 4-2 to request the federal government require developers of a potential hydro-electric project above Chilkoot Lake to conduct additional studies, including examination of insuring against potential losses to fisheries and other values there.

About 35 residents turned out for the special meeting and all but eight of the 25 who testified were cricital of development of hydro at Connelly Lake, located four miles upstream of salmon-rich Chilkoot Lake.
