General Background

Starting right in the thick of it, the history of Union Valley Reservoir is as layered as the fish swimming in its waters. Constructed in the late 1950s amidst the stunning backdrop of El Dorado County, it's not just a body of water; it’s part of an expansive system that supports local wildlife and offers an escape for anglers. The reservoir spans about 2,890 surface acres and sits at an elevation of 4,900 feet, right in the heart of the Sierra Nevada. It’s flanked by the granite ridges of the Eldorado National Forest, and while it was engineered primarily for flood control and water supply, the fishing opportunities it presents are what keep people coming back year after year.

On the fishing front, this place has a lot to offer. Anglers can target a variety of trout, including rainbow, brown, and the impressive Mackinaw, each thriving in the cool, oxygen-rich waters. The reservoir's unique conditions create an ideal habitat, particularly for kokanee salmon during the warmer months, making it a hotspot for those looking to reel in a nice catch. With a little luck and the right techniques, you could easily find yourself landing a stunning trout while soaking in the breathtaking views around you.

How to Plan Your Trip

Thinking about Union Valley Reservoir brings to mind the thrill of catching rainbow and brown trout, along with kokanee and even the elusive Mackinaw. The water’s cool and clear, making it a prime spot for fishing nearly year-round—though spring and summer are when you’ll find the fish most active. Grab your medium-action rod, a smooth-drag reel, and a mix of lures like Rapalas and spoons. Don’t forget to pack some nightcrawlers or PowerBait if you plan to bait fish. Just watching the way the water reflects the surrounding forest can be as rewarding as the catch itself.

Make sure to hit varied spots like the boat ramp or near underwater structures; these areas tend to yield some solid bites, especially if you’re trolling. As for strategies, keeping an eye on seasonal behavior is smart. Kokanee salmon schools can bring bigger surprises, so tuning your approach to where the schooling happens can lead to great catches. Fly fishing fans should definitely try wooly buggers and nymphs—the clear alpine waters are ideal for that. Also, don’t shy away from smallmouth bass; they require a bit of finesse but can add diversity to your day.

Species to Catch and Gear

So, about fishing at Union Valley Reservoir, it's pretty solid for catching a variety of trout. We've got rainbow trout, often hanging around 12 to 18 inches. They're everywhere, thriving in those cool waters, making for a fun day on the lake. Then there's the brown trout, and let me tell you, they can put up a good fight. Some of them reach over 20 inches, so be ready for a challenge. Kokanee salmon, known as "silvers," come around in spring and summer, averaging 12 to 16 inches.

If you're looking for something bigger, that’s where the Mackinaw trout come in. These lake trout can go over 30 pounds, typically lurking in the deeper waters, so you'll want to have the right gear for those hefty catches. Beyond the fishing, the reservoir's home to some interesting wildlife. You might spot a variety of birds overhead, like ospreys and eagles, just hanging around waiting for their next meal. Keep an eye out for deer wandering nearby, too. The whole area's just buzzing with life, making it a great place to soak in nature while you’re fishing.
