In Colorado, water rights are based on the concept of "beneficial use," which has historically been limited to irrigation, municipalities, industry and other off-channel diversions. RICD's (Recreational In-Channel Diversions) are water rights to control water left in the natural channel through boat chutes, etc. The Colorado Supreme Court granted that these water rights constitute beneficial use and are legimitate.
RICD's ensure that future upstream development does not decrease the flow for kayak parks. For example, if Idaho Springs wanted to put in a HUGE reservoir to capture the spring runoff, they would be impeded by Golden's RICD for these high flows.
There are lots of water rights and development implications resulting from RICD's: 1) They can limit future upstream development, 2) they can limit the transfer of water from upstream reaches to downstream reaches, 3) they ensure that investment in a kayak park may be enjoyed into the future... etc.
