Environmental criteria/groups that hydroelectric power projects can face

Unfortunately, that is a very specific question and I do not have particular information on that area. What I can list is a set of topics that may be considered risk factors:

• Earthquake can deteriorate construction
• Excess rain may determine the need to discharge water from the dam and promote floods downstream
• Lack of rain may determine failure to supply water downstream at ecological levels
• High temperature and stagnant waters may develop hazardous bacteria or promote eutrophication
• Blocking the flow of water when it is contaminated, for example, by discharges from a chemical company, preventing contamination downstream (opportunity)
• Destroying or badly affecting traditional river fishing activities due to high variations in water level downstream within a 12 hour period

Do you get the pattern?

Events that may happen, but you cannot say when will it happen

Perhaps the last one is not a risk, there is no uncertainty, it is forecastable and the probability is far from zero.
