| Principle 2: Does climate matter?Lake Chicamba is fed by the Zambezi watershed, gathering 
        water from tributaries in Angola, Zambia, Malawi, Tanzania, and Zimbabwe 
        and flowing eastwards for 3,000 kilometres before reaching the Indian 
        Ocean off Mozambique. Extremes in rainfall over the extensive Zambezi 
        watershed (see 
        map) strongly influence streamflow and ultimately, the water levels 
        in the Chicamba reservoir. Therefore, climate clearly has an impact on 
        Filipe's management decisions.
