If you follow our fishing conditions page on www.arkanglers.com, you know that prophesy is not necessarily my strong suit. Especially when it comes to projecting river flows. I have been watching this river for many years, serve on the Upper Arkansas Water Conservancy District board, and have many contacts in the rarefied chambers of water management. Despite these advantages, I am often surprised, if not downright contradicted, by the behavior of this river in May and June. Now that it is July, I will humbly crawl out of my cave of humility and see if I can see my shadow, or at least see my way out of the woods.
We had an early peak around Memorial Day and then cool weather dropped and cleared the river for awhile. We had a second lower peak in mid-June and then the river dropped again. And then last Friday the river rocketed to its highest flow yet, the result of heat, the high angle of the sun, continued west-slope imports, and full storage vessels on the upper river. Monday morning we were at 3530 cfs at Wellsville. Today we are already back down to 2630 and dropping. It has been a prolonged process but it looks like we are finally headed into summer flows on the Arkansas.
All has not been doom and gloom during this time. The fishing at Antero Reservoir has been insane – many trips catching 30-40 fish or more and many fish over 5 lbs. The upper end of the Arkansas, above the confluence with Lake Creek, has been overrun with caddis and a variety of stoneflies. The main channel has been too burly to fish but the side channels and pockets in the grass have been full of aggressive feeders. Over the last three weeks, most of our high lakes have opened and cruising cutthroats have challenged the blood pressure of a number of ArkAnglers’ guests. All of these waters, and our lovely tributaries, will continue to produce even as we turn our attention back to the Arkansas. There is no shortage of fishing opportunities in July and August!
What can we expect on the big river? I think we will be dropping into the Very Fishable flow range of 1600 and below by early next week. At that level, the river is out of the willows and there is plenty of good structure breaking up the flow along the banks. Golden stoneflies will still be in evidence but yellow sally stoneflies and pale morning dun mayflies will take center stage. Hoppers will be profuse along the banks and caddis, in a variety of sizes and colors, will fill in the gaps. July and August represent some of the best dry fly fishing of the year. Mornings may suggest a beadhead dropper but midday to evening should be double dries along the edges, my favorite combo being a size 16 yellow stimulator followed by a 16-18 light cahill (pmd).
Oceanic and atmospheric observations are suggesting a fair bit of moisture in the rockies this summer. So we may see some days when monsoon rains murk up the lower river and push our trips upstream. Outside of those occasional events, we expect great fishing in Bighorn Sheep Canyon for the next 120 days. Depending on how you look at it, that’s a long time or will be gone before we know it. Either way, we hope you will find your way to the Arkansas this summer or fall.
We update our website almost every day. And we are here on the phones and email from 8-6, seven days a week (8-5 on Sunday). Please call us if we can help you with information, equipment or a trip. And we look forward to your next visit.
