The above two charts are good companion pieces for understanding the evolution of how Lake O has been managed over the years. In 2008, a new regulation scheduled called LORS was implemented to lower Lake stage while the Hoover Dike was being rehabilitated. In terms of stage alone, LORS was fabulously successful. High and low-water extremes were kept in check on par with the 1950s and 1960s. That success story was undermined by the worsening water quality in the pelagic part of the Lake. The Lake’s interior wetlands and coastal estuaries are both intolerant and easily harmed by the eutrophic water.
