The EA position is briefly summarsed on their website: Environment Agency - Our position on hydropower. The Institute of Fisheries Management gives a little more detail: http://www.ifm.org.uk/sites/default/files/page/IFM_Hydropower_position_statement_FINAL.pdf.
The basic concern is that detailed environmental impact assessments need to be conducted - including effects on non-aquatic wildlife like bats which feed on fly hatches along the river corridor.
Apart from looking ugly - it is the way that flow velocities may be changed and this will affect aspects such as aeration and the nature of the riverbed. In the Thames, fast flowing well-oxygenated water is confined in its distribution to weirpools - with an effective lake between each of them. In this case any degradation of the weirpool habitat or function within the rivers ecology could have serious implications for fish not only using the weirpool itself but further downstream.
At least this scheme appears to be a community-led not-for-profit proposal (on the face of it at least), which is more commendable than an energy company in my view.
