The Montana Legislature's water committee will tie up loose ends during its scheduled Oct. 13 meeting, as it finalizes legislation and discusses proposed selenium standards in Lake Koocanusa and the Kootenai River.

The Water Policy Interim Committee will meet via the Zoom platform from 9 a.m. to noon Oct. 13.

The committee will consider preintroduction of bill drafts related to:

  • Weather modification and control statutes (PD0006)
  • Amending water right ownership update process (PD0009)

The WPIC will also discuss a 2019 bill clarifying the use of river basin councils (SB47), and possible language for a Department of Natural Resources and Conservation bill on Berkeley Pit water right exemption.

The Department of Environmental Quality is proposing a new selenium standard for Lake Koocanusa and the Kootenai River, as those identified levels have been rising for at least 15 years to do high-grade coal mining on the Elk River, a British Columbia tributary.

This meeting is open to the public. The meetings will be streamed live on and broadcast on the Montana Public Affairs Network (MPAN). An archived recording of the meeting will also be made immediately available on
