Montana House Bill 309 (redefining irrigation ditches, or limiting stream access) passed the house of representatives this afternoon by a 55-44 vote. I'm not totally sure (didn't pay attention to my school house rock) but I think from here it goes to the senate, then to the governor. My representative, whom I e-mailed more than once, voted yes. He will be getting another e-mail.
