Utah Lake is,in a word,disgusting. The State of Utah has worked with many partners and spent millions of dollars in an attempt to restore Utah Lake. It has indeed produced some active effects.  However,due to the waste water getting into it,this body of water is rich in  nutrient and home to water bloom.  Over fishing and the introduction of invasive species have only made the problem worse. In the summer of 2016，500 people in Utah complained about their headaches, skin rashes and discomfort after swimming in the lake.
  The Utah Lake Restoration Project is headed by Parker. He imagines a beautiful lake dotted with man-made islands where a community could be built. Parker frequently goes to Capitol Hill to push for the proposal of the comprehensive lake restoration. Parker follows his rules "big ideas are worth approaching"，as the project calls for lake digging,the creation of islands,the removal of invasive species to restore the habitats of native plants,fish and so on.
  Speaking of the Utah Lake Restoration Project,Ben Holcomb said,"It is not quite in line with reality." He added,"Despite impressive computer models and the current project report,the Utah Lake Restoration Project lacks the actual field research to show that this project will have a positive effect on the lake's ecosystem."
  When asked how the public would help beautify Utah Lake,the lake's official workers suggested picking up garbage. However,it has a greatly limited effect on the overall health of the lake. Parker's plan may seem like the state's best chance to restore Utah Lake,but in reality the Utah Lake Restoration Project lacks the facts necessary for this sort of proposal. The State of Utah should propose some suggestions for the revision of the plan and offer the Utah Lake Restoration Project the access necessary to conduct research which could be compared with their theoretical findings. Only then can the State of Utah make an educated decision on behalf of people and resources.
