DIY Guide to Fly Fishing Spinney Mountain Reservoir in Colorado

Every April, hundreds of anglers rise early in the morning and sit in their cars and trucks waiting for the fabled Spinney Mountain Reservoir to open for the season. 

Yes, the fishing at Spinney Reservoir is so storied and and so legendary that locals and fishing tourists alike line up before the sun rises to get in and get on the water first.

Why the long lines and first day rush?

Spinney Mountain Reservoir closes in the winter time, and it doesn’t reopen until after ice breakup.

Anglers and fisherman alike are intent on being first to cast and land giant trout rising up from the depths to feed after a long winter.

Despite the limited time to fish each day (sunup to sundown), there is a lot of potential waiting in these Gold Medal waters. Spinney Mountain Reservoir is known for their giant rainbow trout, extra large brown trout, and rainbow/cutthroat hybrids that swim the long-sleeping waters of the reservoir each year.

Best Places to Fish Spinney Mountain Reservoir

Fly fishing is excellent all around the shores of the reservoir, and boats are permitted for those who wish to bring them. Repeat visitors to the reservoir find that boating improves their chances of catching that giant rainbow they’ve been after for years.

Most veterans of Spinney Mountain Reservoir advise against using floats though, as the winds are unpredictable, and storms have a habit of springing up suddenly. Be sure to keep well away from the dam whether you are fishing above or below it though, as fishing is prohibited in these areas.

While you boating may be the preferred method for fishing at the reservoir, those who take a waders-only approach to fly fishing will not be disappointed. The reservoir itself has over 2500 surface acres for you to try, and even if you find a spot and feel like moving on later in the day, there’s plenty of room to do so.

Don’t forget to pack plenty of supplies, bug spray, sunscreen, and drinking water though, as the nearest store is several miles away from the lake, and you don’t want to miss prime fishing time because you run out of a necessity.

Best Time to Fish Spinney Mountain Reservoir

The only time fishing is permitted at Spinney Mountain Reservoir is spring after the ice thaws until early autumn. The Division of Wildlife does not permit ice fishing at the reservoir, and everything is covered in thick layers of ice during the coldest months of the year. You want to make reservations locally well ahead of time if you are planning an extended trip too, especially if you are looking to visit on or around opening day. Local cabins, campgrounds, hotels, and other accommodations fill up fast.
