Jordan: If you look at a map you will see that hwy 287 goes north out of Ft Collins, a few miles to the north hwy 14 goes off to the west, that intersection is a convenience store and gas station called "Ted's Place". Hwy 14 leads into Poudre Canyon and follows the river for the entire length. Also get a good map of Ft Collins and you will see how the Poudre runs through town, with a little exploring you will be able to see if there are any trout left in the river after the fire. There also is some GREAT fishing to be had over at the Delaney Buttes lakes that are located about 10 miles west of Walden, CO.....you drive west on hwy 14 all the way through Poudre Canyon to reach Waldon.......this is best fished with a float tube or small pontoon boat. As JMAC mentioned, there also is some great fishing in the Snowies to the north of Ft Collins, you would drive north on hwy 287 to Laramie, then head west on hwy 130 to the Snowie Mtns. Lots of small streams and lakes in the area to explore, get yourself a copy of the Medicine Bow NF to find what I'm referring to. Also the headwaters of the North Platte River originate in the Walden, CO area (there is a fly shop in town called North Park Anglers. North Park Anglers
Stop in and talk with them about fishing and where to go. If you drive north out of Walden, CO on hwy 125, it connects to hwy 230 heading west. At that point start looking on the right side of the road for the brown public access signs that lead into the North Platte river, I think there are 4-5 access points.
Don't forget to do some exploring around Ft Collins, there are tons of lakes to fish warm water species, most will be on private land, but take the time to knock on some doors and ask politely about the possibility of fishing......you might be surprised at the gems you discover. For example, my son has access to a private pond in Longmont that we take the 4 year old grandson to for some excellent smallmouth bass fishing and the best part is that I have never seen another angler on that water so it is like having access to our own private lake and the fishing is just awesome.
Also stop in Laramie at the Four Seasons Fly Shop and pickup a copy of the sagebrush lakes map around that area, there is some excellent fishing to be had, especially in the spring and those lakes are small enough that you can wade effectively.
Just south of Casper on hwy 220 there are several public access points (just look for the brown access signs) to the North Platte, which provides excellent fishing.
