Island Park Idaho - Hotel, Lodging, Recreation, and Fishing

ISLAND PARK ID- As fishing season approaches, many anglers may be wondering how trout populations in the area look.  In order to find out, biologists from the Idaho Department of Fish & Game (IDFG) recently completed annual population surveys on the Henrys Fork.
 
The survey process involves using drift boats equipped with portable generators to run an electrical current into the water.  Fish are temporarily stunned, which allows netters to collect them for marking and measuring.   After one week, the biologists repeat the process, and record the ratio of marked to unmarked fish, which allows them to estimate the total population in that section of river. 
 
Nearly every year, surveys are conducted in the famous Box Canyon.  This helps fishery and water managers learn how flows from Island Park Dam affect trout populations, thereby guiding future decisions.  Unfortunately, low flows last spring precluded estimates for 2004.  Other reaches of the river are surveyed on a multi-year basis.  This year the stretch from Vernon Bridge to the Chester backwaters was surveyed.
