Opposition arose because the dams are expected to disrupt the major source of the Amazon, alter normal silt deposition into the lower river, damage habitat and migration patterns for fish and other aquatic life, displace thousands of residents along the river, and damage a national treasure "at least as nice as the Grand Canyon in the USA". Residents have launched efforts to halt the dams along the river with conservation groups such as SierraRios<ref>{{cite web | url=http://www.sierrarios.org/Peru/SaveRioMaranon.html | title=Save Río Marañon | publisher=sierrarios.org | date=n.d. | access-date=22 February 2013}}</ref><ref>{{cite web | url=http://www.psf.org.pe/institucional/wp-content/uploads/2014/04/infografia-chadin2.pdf | title=Graves impactos de la represa Chadín 2 | publisher=Forum Solidaridad Peru | work=Infographic | date=23 September 2013 | access-date=5 May 2016}}</ref> and [[International Rivers]].<ref>{{cite web | url=http://www.internationalrivers.org/campaigns/marañon-river/ | title=Río Marañon | publisher=International Rivers | date=n.d. | access-date=22 February 2013}}</ref>

Potential ecological impacts of 151 new dams greater than 2 MW on five of the six major Andean tributaries of the Amazon over the next 20 years are estimated to be high, including the first major break in connectivity between Andean headwaters and lowland Amazon and deforestation due to infrastructure.<ref name="plos">{{cite journal | title=Proliferation of Hydroelectric Dams in the Andean Amazon and Implications for Andes-Amazon Connectivity. | author=Finer M, Jenkins CN | journal=PLOS ONE | year=2012 | volume=7 | issue=4 | pages=e35126 | doi=10.1371/journal.pone.0035126 | pmid=22529979 | pmc=3329437| bibcode=2012PLoSO...735126F | doi-access=free }}</ref>
