On 16 May 2014, CSPA joined Friends of the River and 40 other environmental, fishing and whitewater organizations in expressing opposition to H.R. 3964 in separate letters to Senators Udall, Feinstein and Boxer. The Bill attempts to commandeer water from other legal users of water and dedicated environmental flows, waives major elements of state and federal law and de-designates a portion of the Merced wild and scenic river.
