SALT LAKE CITY — A local environmental activist convicted of assaulting his former girlfriend has been sentenced to jail.

Jeffrey Charles Salt, 53, who directs the Great Salt Lakekeeper in its efforts to "protect, preserve and defend" lake resources, was sentenced to 90 days in jail Monday by 3rd District Court Judge William Barrett. The man was also ordered to perform 75 hours of community service.

Salt was found guilty of aggravated assault, a third-degree felony, by a jury in March. The jury acquitted Salt on charges of aggravated kidnapping, a first-degree felony, and damaging or interrupting a communication device, a class B misdemeanor.

The charges stem from a 2008 altercation between Salt and his ex-girlfriend in which Salt apparently twisted the woman's neck and hit her with a piece of pottery and a pipe. Defense attorneys Ed Brass and Kim Cordova argued at trial that Salt was acting in self-defense.

Salt has been an advocate for the Great Salt Lake and Jordan River Restoration Network, among other things, and pushed to do such things as protect area rivers and inform the public about mercury levels in Utah's watershed.

Salt was given credit for 25 days he has already served. He is to report to jail by Nov. 13.
