Abstract: A systems
approach is used to present the tradeoffs between power generating capacity and impacts
to streamflow and river connectivity among different scenarios of hydropower development
in the Alto Magdalena River basin, Colombia. This analysis defines a non-inferior set of
15 development scenarios which minimize connectivity loss while maximizing generating
capacity. Streamflow ... read moreimpacts were assessed using WEAP, and results show that while
building reservoirs upstream of existing dams best maintains connectivity, this causes
greater local streamflow impacts than downstream development. Upstream consequences may
affect a smaller fish population than downstream, but this population is largely
endemic. Impacts of upstream development on downstream flows are minor due to the
influence of existing dams between the two reaches. This work provides information to
support the decision making process in hydropower development and suggests the need for
cooperation among local and national entities as well as for a larger set of performance
measures.
