2015 Conference - touring Diamond Valley Lake

posted Jul 23, 2015, 9:21 AM by CALMS webmaster   [ updated Sep 3, 2015, 3:35 PM ]

This year's annual conference will feature a day two tour of the largest reservoir in Southern California, Diamond Valley Lake in the city of Hemet.  Filled in 2002, this relatively young lake's 800,000 acre-feet of storage has been instrumental for maintaining the region's supply during the current drought era.  However, the reservoir is down to under 50 percent of capacity, and could potentially reach 25 percent before the next winter season.  Complicating management of the reservoir, Quagga mussels have prevented the input of any Colorado River water into DVL since 2007.  Since that time, the reservoir has been filled with high nutrient water from the California Aqueduct system, prompting plans for adjusted lake management strategies to contend with steadily increasing frequencies of taste and odor producing phytoplankton blooms in the epilimnion and summer oxygen depletion in the hypolimnion.
