Duck hunting

If I want to hunt the banks of the snake river along map rock (not in front of the airport of course) but along the water below the highway and trench Through the Russian olive trees; can I game to shoot as long as my shot is towards the water?
Also, I went and took my step son out to teach him do's and don'ts about hunting. Our location was the Roswell Marsh Wma off pin and marker rd. Can we hunt the ponds across hwy 18 to the east?

Answer: 

That area is a little tough to hunt because in many places it is a very narrow strip of land between the road and river.  You can hunt on private land along the river with permission from the landowner or along any public land that is open. We emphasize safety and respect for property.  Also, it is very important to have the ability to retrieve ducks (boat or retriever, or both), and remember it is illegal for you to have your dog retrieve down birds on private property that you do not have permission to access.  You can access the water along that stretch of road by public boat launches.
 
Not sure we are following your question about the Roswell March WMA. The road runs east and west.  The ponds on the south side of Hwy 18 are public and managed by IDFG (with hunt days of Thurs/Fri/Sat only) and upland portion of Roswell can be hunted 7 days/week.  The ponds north of Hwy 18 are private.  Here is a link to a map of the area.
