Summit County
Blue River
The Blue below Dillon Reservoir, running straight through Silverthorne and on north, with a further tailwater section below Green Mountain Reservoir.

What the water is like
The upper section is genuinely urban tailwater: outlet mall on one bank, trout in the run below. Flows are dictated by reservoir releases rather than weather, which makes the river both more predictable and capable of changing overnight.
Getting on it
Public access through Silverthorne is easy and signposted. Downstream the frontage becomes a patchwork of public and private, and the boundaries matter.
Access arrangements are the single thing most worth confirming before you drive. Public frontage, parking, fees and seasonal closures all change, and on several Colorado rivers the boundary between public and private water is neither obvious nor forgiving. Check with Colorado Parks and Wildlife and, where the water runs through a national park or a federally managed area, with the agency that manages it.
