On April 30, 2008 FERC issued a license for operation of the Ottumwa project located on Des Moines River in Ottumwa, IA- 80 miles southeast of Des Moines. This 3.25 MW project is operated as run-of-river consisting of a 18-foot high dam and three generating units.The license is issued on a condition that the City of Ottumwa, which operates the project, will provide FERC with plans and schedules regarding dam safety operations within 6 months of issuance of this license.
The Federal Energy Regulatory Commission released the Environmental Assessment for the Ottumwa Hydropower Project (P-925) last month in which it recommended licensing of this 3.2 MW project located on the Des Moines river in the City of Ottumwa. In the EA, FERC has identified fish entrainment mortality as an "unavoidable adverse impact" but stated that this long term impact is expected to be minor. Comments can be filed with the FERC secretary by Jan 21, 2008.
