Golf practice ranges in Ottawa Lake are the areas where golfers can practice their swing. There is also provision for recreational activity for amateur golfers. Golf practice ranges also have a driving range attached and they are also found as stand-alone facilities, especially in urban areas in Ottawa Lake. They are typically run by businesses or sometimes by universities. Distances are usually marked by target greens at regular distances. Driving ranges may have natural grass, similar to a golf course, or players may have to use synthetic mats that resemble real turf.
