28 CUMULATIVE IMPACT ASSESSMENT OF ST. PAUL RIVER DEVELOPMENT
28.1 Scope
This Chapter provides an assessment of cumulative impacts of the planned hydropower
cascade on Mount Coffee River. The assessment is done entirely based on available
documentation and information. No site visits to or specific field work for the three
planned reservoirs upstream of Mt. Coffee HPP were carried out.
28.2 The St. Paul River Cascade
A short description of the cascade was provided in Section 3.7. For easier reference, the
figure providing an overview of the cascade is reproduced here.

The cascade to be used as a reference for the CIA still needs to be defined. Presently,
there are mainly two descriptions, one provided in the Main 1982 reports, the other from
the Stanley 2008 report. The latter focuses on the “Optimal” Mt. Coffee Development
