Is it legal to shoot ground squirrels north of the Payette river?

Most of the ground squirrels north of the Payette River are protected ground Squirrels which can not be hunted.  Idaho has two species of ground squirrel that are only found in Southwest Idaho.  The Northern Idaho Ground Squirrel lives in Washington and Adams counties, they are a federally protected Threatened Species.  The Southern Idaho Ground Squirrel lives in Washington, Payette and Gem counties and are a state protected ground squirrel.  Northern and Southern Idaho Ground Squirrels are small squirrels. The unprotected Columbian Ground Squirrel is a larger ground squirrel and can be hunted if the shooter has a valid hunting license and can identify the squirrel as the unprotected species.
