From reading the code, my take away is your not supposed do any activity inside of 200 yards of source of water longer then 30 mins.Don't blame me, I got info from DFG site. Also, Read Sprigs post #15, section 730(a). But like anything put out by DFG, it's as clear as mud.
So walking by a guzzler and hunting would be fine but hunting dove by the farm ponds for 30+ wouldn't? Wow that sounds so stupid about dove just typing it out, I can't imagine anybody get cited for that.
