DENVER — American Whitewater floated a plan last year to expand protections for recreational river flows in Colorado. Maybe, the nonprofit protector of rivers thought, communities should not need to build whitewater parks to secure rights for recreational flows.

Colorado officially recognized recreation in a river as a beneficial use of water in 2001, enabling riverside communities to file for water rights to support whitewater parks. Those recreational in-channel diversion water rights, or RICDs, set a minimal stream flow between structures to support “a reasonable recreation experience.”

The nonprofit river conservation group American Whitewater is advancing a plan that structures in the river are not necessary for river recreation and communities should be able to file for RICD water rights without expensively engineered features that create waves and holes for kayaking, rafting and stand-up paddling. While there are 13 official RICD water rights in the state, there are more than 130 stretches of whitewater that can be rafted, kayaked and stand-up paddled in the state.

Early talks with Colorado’s sharp-elbowed water community have not gone well. No lawmaker took up American Whitewater’s proposed legislation, which has been scrapped. And opposition to a plan that expands recreational protection of water is stiff.

The gist of opposition, which was voiced earlier this month at the meeting of the statehouse Water Resources Review Committee, is this: If any community can file for RICD water rights without actually building anything in the river, the expansion of those recreational rights could muddy Colorado’s already complicated water dealing.
