4 Lake Lorene Experimental Treatment Public Meeting TLHOA hired an environmental consultant to collect data to assess lake conditions and to identify potential approaches for solving problems related to water quality and aquatic plants in the lake. A report was issued suggesting: Develop & implement a water quality monitoring program to identify the primary external sources of phosphorus Reduce external phosphorus loading from the watershed Homeowners are complaining Lake management company hired. They suggested Add Sterile Carp to reduce aquatic plants Install aeration equipment & use additive Revive to help with the Algae carp added, aeration system installed & Revive addition commenced A “little” history

5 Lake Lorene Experimental Treatment Public Meeting Still using Revive, conditions are degrading each year. Blue- Green Algae is prevalent in the warm months. Weeds are under control Lake management company reports the most significant source of Phosphorus is coming out of the sediment. They suggested Phoslock. Added first installment Added second installment of Phoslock.... Life on the lake is good! Due to threat of legal action, no sign of the management company. We don't need them, things are great...or are they? Late June thru September. Blue Green Algae is present, weekly samples remain toxic – Commenced sampling Joe’s Creek and confirmed Soluble Phosphorus flowing into Lorene at a very high concentration – Partnered with the City of Federal Way to investigate.
