The 200 square miles of watershed in Salt Lake Valley's seven major canyons are being increasingly threatened by development and recreational use, especially in recent years, and Salt Lake City, which holds the water rights to canyon water, has prepared an update of its watershed management plan to deal with the problem.

The draft plan contains requirements and restrictions on camping, picnicking, dogs and the like, as well as administrative things such as signage, cooperation between agencies and picnic ground management. There will be a public hearing on the plan today at 5 p.m. in room 315 of the Salt Lake City-County Building, 451 S. State, to receive public input.The Planning Commission and Public Utilities Advisory Committee will then finalize the plan and send it on to the City Council.
