MT ST Helens

MANAGEMENT

to reduce the risk. pre eruption

• monitoring
• blocked off roads

• restricted access

After the eruption. recovery

• water in Spirit lake was found to contain a disease, so stopped use and monitored water
• risk of mudflows and flood, so they pumped water away from Spirit lake while a outlet tunnel was created to maintain the Lake at a safe level
• also to decrease risk of mudflows and flood, sediment dams created on Toutle River, however soon river filled with sediment so river had to be dredged
• Many Lakes restocked with fish, to restore popular recreational fisheries

Good perceptions

• popular attraction, St Helens monument made. attracts tourist to the area
• recreation opportunities
• one business took some of the huge amounts of ash produced to make "genuine Mt St Helens ash trays"
• digger companies etc. get money to dig out ash.
• builders get work to rebuild houses, roads, bridges

Bad Perceptions

• transport such as roads near the area were destroyed.
• tribes had to leave their home and traditional way of life
• jobs lost, loggers worked there can't anymore due to the 156 acres of trees being blown over and burnt
