In the spring of 1982, 3,000 Eniwa citizens planted approximately 1,000 cherry trees on the right bank downstream of the dam to make "Eniwa Lake" a place of relaxation and enjoyment for the citizens as Cherry Blossom Park. The conditions in the park were not good for cherry trees to grow (soil, temperature, etc.), and some of the trees began to die. (Chishima cherry, Ezo cherry, Beni cherry, etc.)
