In one of the earliest major dam projects in Colorado, a 550 foot long, 111 feet high earthen and rock dam was built creating the Rio Grande Reservoir in Hinsdale County. It’s located between Lake City and Creede on Highway 149.
“Too thick to drink, too thin to plow,” was said of the Rio Grande by an early immigrant to the historic Texas River. The headwaters of this historically divisive river lies a few hundred miles north in the Colorado Rockies. The Rio Grande Reservoir lies 1 hour from Creede and 1.2 hours from Lake City.
The original intent for the reservoir created behind it was for agriculture in the San Luis Valley, but over the years the lake has grown in popularity for fishing and recreation. It was built from 1910 to 1914. Long and narrow, the Rio Grande Reservoir is the third-highest major reservoir in Colorado at an elevation of 9,400 feet and contains 51,110 acre-feet of water.
Boating and fishing are the primary activities, but a wide range of outdoor activities including mountain biking, horseback riding, camping, climbing, hunting, and hiking are available in the Rio Grande National Forest that surrounds the reservoir.
Boating: The reservoir is stocked each summer and motorized boats are allowed. There is a boat ramp cut into the bank halfway up the length of the lake, but it is not recommended for large boats or long trailers. There are boat ramps, toilets, drinking water, ample parking, and no fees to use the Boating Site.
Nearby the Rio Grande Reservoir there is rafting on the Rio Grande River. May to September you can find commercial raft trips with varying degrees of difficulty. Late June is best for peak whitewater conditions.
