Latest Update: 4/18/2024

Here are the current streamflow conditions for the Big Thompson River:
– Big T Above Lake Estes: 70 cfs
– Big T Below Lake Estes: 90 cfs
– Moraine Park: 32 cfs

Please note that water levels on the Big Thompson have been showing slight fluctuations each day, so it’s a good idea to check the flows before setting out on your fishing expedition. Lately, the river has been bustling with activity, especially with the prevalent hatch of blue wing olives, which the fish seem to be quite fond of.

For the optimal angling experience, it’s recommended to start nymphing early in the day before the sun’s warmth triggers increased insect activity. Once you observe the bugs coming to life, consider switching to a smaller BWO dry fly paired with an emerger pattern or perhaps try a smaller hopper dropper rig. As the day progresses, transitioning to patterns like BWO nymphs, pheasant tails, or smaller stoneflies can yield favorable results.

In the coming weeks, keep in mind that rainbow trout will likely begin their spawning rituals in the shallow riffles. It’s crucial to give them the space they need to ensure the health and sustainability of future fish populations. If you have any inquiries or require further guidance on fishing the Big Thompson, don’t hesitate to reach out.
