I received a great question today: “How about a straight answer about fishing the river at the level it is at right now. I was told I’m crazy for staying away – my thought is it’s not good for the fish or the fisherman. Be honest please.” I’m assuming the question is about the Farmington.
Those of you who know me know I have nothing to sell you but the truth. So here we go.
The simple answer is: most of the time, yes. The Farmington is, after all, a tailwater. If you’re unsure what that means, its flow is generated by a bottom dam release, in this case Hogback Reservoir. In an average year, the reservoir will have a good amount of water in it, such that the bottom strata will be much cooler than the surface. I can tell you from experience that I’ve shivered for hours in the river on a 90 degree day in July. That water is plenty cold.
Fog is what happens when frosty water meets warm, humid air. This shot is from mid-summer.
What happens in a drought year? In the most extreme years, it can get ugly. Go back to our most recent severe drought year, 2016. The water release was in the paltry double digits, and because there was so little water in the reservoir, what was coming out of the chute was in the mid 60s — not good. Take that water, bake it over several miles, and we had fish kills. The DEEP even declared thermal refuges, unprecedented for the Farmington River. I advised people to not fish.
So what about right now? The release is 118cfs, not great, but it’s coming out cold (the Still is adding 12cfs for a total of 130) as we had plenty of water this spring. Where you fish matters. The run from Hogback to Riverton right is plenty healthy for fish. Naturally, it will warm as it travels downstream. The water may be stressful to trout by the time it gets to Unionville. But every day is different — today it’s cloudy and in the upper 70s, not exactly a river-under-a-heat lamp. If it were sunny and blast-furnace hot, you’d have a different dynamic.
When you fish matters, too. From dawn through when the sun tops the trees is the coolest the river will be on any given summer day.
In conclusion: Use the stoutest tippet you can to get those fish in fast. Don’t take them out of the water. Fish when and where the water is coolest. Use common sense, and you’ll fish with a clear conscience.
Steve do you carry a thermometer and if so what is the number that will stop you from fishing ?
I do carry, but it’s more for personal record-keeping than anything. I tend to take a “by feel” common sense approach like I talked about above. This time of year in these conditions, I’m fishing early or late, and if it’s mid-day it’s closer to the dam and in faster (more oxygenated) water. I don’t know the exact number where it starts becoming stressful to trout — I’m sure there are plenty of search answers on the web. Point is — if you have to measure the water temp, it’s probably too warm.
