If I am hunting in a desert area can I set up a water tank to attract big game?
As found on page 98 of the Big Game 2014 Seasons and Rules brochure: It us unlawful to: Hunt any game animal by means of baiting with the exception of applicable rules for black bear baiting permit (See pages 69 and 70). Bait is defined as any substance placed to attract game animals, except liquid scent for deer and elk.
Water is considered "any substance" and cannot be placed for the purposes of attracting big game.. However, there is nothing wrong locating an existing water hole and setting a blind to hunt.
