The science of controlling snow has long enough history. According to Brown (1983), the first known reference to snow fences was in an 1852 Norwegian publication describing snow fences as a means of providing water for livestock. Another early reference was an article that appeared in an Alaskan newspaper (Seward Weekly Gateway, 1909) describing miners using snow fences to augment water supplies for placer mining. Since then there has been considerable progress achieved with using snow fences to increase water yield or local water supplies (Jairell and Schmidt, 1990; Tabler, 1989; Slaughter et al., 1975).
