Its shoreline is heavily populated with homes and it has limited public access. There are four boat launches, three of them public. Originally known as Lake Hayden, it is now more commonly known as Hayden Lake, to match the eponymous city located on the lakes shores.{{Citation needed|date=October 2023}}
