Some winter conditions around Ouray County are quite harsh and may mean that fishing or even driving to the lake can be dangerous or even downright impossible. The best time of year to fish in Crystal Lake is after the spring thaw and the ground and water have returned from their icy state and the lake and skies are filled with life and hunger from the long winter.

The warmest months of summer are the best time to fish here and at any lake in the area. Since only artificial lures are allowed here, you should talk to some local anglers to find out what flies are hatching and which lures to be casting in the water to increase your chances of catching more fish.

Best Weekend to Fish in Colorado?

The first full weekend of June each and every year is a ‘free fishing weekend’! You don’t need a license to fish this weekend. Check your calendar!

Best Time of Day to Fish in Crystal Lake Colorado

If you fish at the wrong time of day, you’ll be rewarded with some great views but no fish. It's probably still worth it to go! Be sure to know all you can about the fishing season, what's biting, what they prefer to eat, and what the weather is like so you don’t waste your time going at the wrong time.

The best time to fish in Crystal Lake during the summer is about mid-morning to mid-afternoon or from 9 am to 4 pm. when the sun is hitting the water and there is the most insect and fish activity on the lake. If the water remains warm in the late afternoon, fish will also continue to feed up until dark.

Spring and Fall

Clear Creek offers fantastic fishing during the spring and fall months. Spring is an excellent time to plan a visit to the area with a stop at Crystal Lake. There are several fish hatches in the spring and fall that make it a great time to fish in this lake. If you're really serious about fishing and catching, come during the warm part of the year and fish the warm part of the day during Spring and Fall and you'll catch fish on your fly rod.


Summer warms the water the most at Crystal Lake, but some fish may have a slow start to their day and not be ready at the break of dawn like you are. For the best results, fish from mid-morning to mid-afternoon, or about 9 am. to 4 pm. If the water is warm in the morning like it usually is during late summer, fish start to bite at sunrise and continue to bite late in the afternoon.


Crystal Lake is not a great fishing spot in the winter, especially during cold weather. It can reach freezing temperatures (-32°F) early in winter and the poor fishing conditions will continue until the spring thaw begins in April or May.

The Right Gear to Carry to Crystal Lake

Fishing in Crystal Lake in Ouray County offers some of the best fishing experiences in the surrounding area. Grab your flies and a pair of waders if you like, and go catch some fish! Try casting nymphs and streamers to get a feel for what the fish are interested in during the time you are there.

Crystal Lake is actually a large pond and not even a lake, so you can expect a lot of fishing on the shore and there's no need to really walk into the water. You can fish with just your waist waders, but you might enjoy the warmth that chest waders can provide in the cool air.

Try fishing with some of your favorite flies and streamers to see if you are able to catch some fish. It is fine to fish Crystal Lake without a heavy outfit, just an 8 – 10 foot rig rated for 6 lb. or less will suffice. Remember, this is not a big lake and fish here will not be lunker size!

Necessary Equipment

Bring your fly fishing rod for optimal fishing in this amazing setting. Rubber boots or waist waders may be used to keep dry, the bank can be wet and slippery. Bring all gear necessary to catch small trout or bass. A simple 7-foot pole with a fly line or for spinning rods will work well. The lighter the action, the better. A simple 1000-2000 rated fishing reel is sufficient for the small fish in these alpine lakes high in the mountains.

A fishing vest and lanyard filled with your usual gear will be appreciated as you cycle through flies or other artificials to see what the fish are biting that day.

If it's winter, you should be prepared for snow storms, hail, rain, and even landslides. Stock extra food and water, an emergency phone, or a GPS system to help you get out of any jam. Remember there are bears and mountain lions around, and you may want to ensure you have some bear spray close at hand.

Wrapping Up

Fishing success at Crystal Lake in Colorado can vary in some years as the lake appears to be fished out after a lot of fishing pressure during especially busy seasons.

You can look at Crystal Lake, a huge pond or a small lake. Either way, it's not going to hold massive fish and you're not going to catch a Colorado record-size fish here! Still, this is some of the most beautiful country the United States has to offer. This is a very accessible lake for anyone in a vehicle and there is a parking area close to the lake.

Make sure you have the proper fishing licenses for anyone with a line in the water and take care to leave the place just as it was in its pristine state when you arrived. Take care not to use live or dead bait, and only use artificial lures and flies.

If you would, practice catch and release so this small fishery can continue to exist and provide sporting entertainment for thousands more people over the years. Small lakes like this can easily become overfished and there is little regulation here, only when the rangers decide to go have a look.

Oh, and one other thing! There are private lakes named Crystal Lake which you may find when you search online for this location. We are not covering any private location in this article, only the public lake located at these GPS coordinates: 37.95832449071744, -107.66504140504142.
