The artificial lake, known as Blue Rock Dam or Blue Rock Lake, is named for an early goldmine in the area. Construction of the dam began in 1979 and was completed in 1984. The dam has a potential capacity of 208,000 megalitres. In conjunction with other supplies such as the Moondarra Reservoir, it provides water for household use, agriculture, industry, and power generation in surrounding areas, particularly in the Latrobe Valley. The lake is also used for recreational activities including fishing, sailing, swimming and picnicking. The lake is surrounded by farmland, bushland and, to the base of Blue Rock Road, the township of Willow Grove.
The community is serviced by a kindergarten and a public primary school, Willow Grove Primary School. At secondary level, students usually travel by school bus to the nearby towns of Moe, Trafalgar or Warragul/Drouin to attend Lowanna Secondary College, Lavalla Catholic College, Trafalgar High School, Chairo Christian School or Marist-Sion College.
The main industry in the Willow Grove area is dairy farming.
