Of the fifteen impaired stream and reservoir segments tracked within ten miles of here, most now carry a federally approved cleanup plan, and Emigration Creek has moved a step further into active implementation. Four still haven't reached that point: Mill Creek near Davis, Hardscrabble Creek, State Canal, and Stone Creek-1 remain listed as impaired with no completed plan in place.
That distinction is not just paperwork. An approved cleanup plan, formally a total maximum daily load, sets an enforceable cap on how much pollutant a waterway can absorb and still meet water quality standards. Without one, an impaired creek stays impaired indefinitely, with no regulatory clock running toward a fix. Utah Water Ways Inc has been working the plan process for Mill Creek and Hardscrabble alongside segments of the Jordan River, so the gap isn't for lack of local attention. It's a measure of how much technical and administrative work sits between identifying a problem stream and actually holding it to a standard.
Separately, SLC PORT GLC PHASE 4, a permitted discharger located west of the city near Magna, is currently flagged for significant non-compliance, though the specific violation record isn't detailed and there's no established hydrological connection between that facility and the four impaired creeks named above — the two are separate items in the local water-quality picture, not a linked cause and effect.
Worth noting separately: a handful of other segments nearby, including Red Butte Creek Upper and Little Dell Reservoir, are only listed as "not impaired" because there isn't enough data to say otherwise, not because they've been confirmed clean. In a watershed this data-limited, the absence of a red flag is not the same as a clean bill of health.
