Riverbend prepared a Feasibility Analysis Report for Low Head Dam Modifications to the Animas Pump Station Diversion on the Animas River at Penny Lane Dam in August of 2013. This low head dam was constructed in 1984 to allow for diversion of water from the Animas River for the public water supply of the City of Farmington. Water taken out of the river is pumped up to Lake Farmington, a raw water storage facility located on a hilltop to the north.
Since its construction the dam and diversion facilities had met the project goals for water diversion, but had created the un-intended consequence of preventing fish passage and the un-desirable effect of dangerous hydraulic conditions for boats to float through (resulting in two deaths, in 2005 and 2011).
Riverbend conducted a feasibility study which included design alternatives to improve fish passage conditions, and to improve boater safety conditions, as well as building a whitewater wave feature at this location. Final design and environmental documentation were completed in 2015, and construction took place October 2016 – January 2017. Now on the Animas River fish can travel up and downstream, and the new waves provide two options (two degrees of difficulty) for fun and safe boating from the way from Colorado/ New Mexico state line all the way to Kirtland.
