Impacts of recreational power-boating on freshwater ecosystems
‘Water-based recreation forms a major value of water resources to the community . . .’ (Ofﬁce of the Commissioner for the Environment,Victoria, 1988). ‘The trail bike, the power boat and the snowmobile are seen as symbolic of a society that arrogantly exploits and consumes re-sources’ (Pigram, 1983). With an increase in lei-sure time available to the majority of the working population over the years, the opportunities to pursue outdoor recreational activities have risen. In particular, more active, water-based sports, including activities such as water-skiing and power-boating, appear to be high on the list of desirable outdoor leisure pursuits and have grown rapidly in popularity (Jaakson, 1970; Tanner, 1973; Craig, 1977; McCall and McCall, 1977; Pigram, 1983). Power-boating, in particular, has increased quite signiﬁcantly since the 1960s (Horsfall et al., 1988; Hodges, 1991); this includes both boating per se and boating for the purpose of towing water-skiers. In Australia, Mercer (1977) reported that power-boating and water-skiing are increasing at a rate of 20–24% per year, while Prosser (1985) commented on the fast increase in the number of people taking part in water-based recreational activities.
