Lower Blue: From I-70, take the Silverthorne exit. If you want to fish just below the dam, take a left when you exit, and go under the interstate. Take a right at the traffic light, and when you cross the river, take the first left. Follow this dirt road for about half a mile until you reach the dam.
To fish at the factory stores there are plenty of places to park, depending on which part of the river you want to fish.
