Marker Wadden in the Netherlands is a similar sized ongoing project that has seen remarkable success with regard to ecological recovery.
The Utah Lake Restoration Project is one of the largest restoration projects ever undertaken, but it is really a series of manageable projects, each with measurable benefits. The project is divided into 5 phases, and a total of 34 islands with full completion estimated to be between 12 and 15 years. If only one island or one phase were completed, the environmental benefits would be tremendous, with significant reductions in nutrient-loaded sediments, increased lake storage, and reduced evaporation. Of course the full environmental benefit is realized when the full project needs are completed.
The dredge containment areas (islands) being created are individually smaller in size than other dredging and island creation projects around the world. Other projects with much larger islands have been successfully created throughout the world. Island creation technologies have been used for over 100 years.
