Let’s clarify: too much rain is harmful, even dangerous. But that’s not what we’re talking about today. We’re talking about a parched state that was experiencing some form of drought for several weeks. Then the rains came. From the July 4th weather brawl through yesterday, the skies were open for a much-needed watering.
At first, even though the rainfall could be measured in inches, there was no visible impact to our two major fly fishing rivers, the Farmington and the Housatonic. Two factors were in play: the ground was a dry sponge, and the trees and vegetation were in full leaf, meaning you had millions of thirsty plants. But eventually, the rivers got their share. The Hous has yet to spike, rising more than double its 350cfs pre-rain mark. The Farmington experience was more of an exercise in moderation. The Unionville gauge merely doubled from 250. The Still River, which meets the Farmington below Riverton, experienced a huge percentile flow boost. However, it was only coming in at a paltry 15cfs, and its spike didn’t even reach 200cfs.
We desperately needed this rain, and I’m thankful for it. But not just from a systemic ecological point-of-view.

You see, I’m a total weather and stream flow nerd. I watch the River Data app like a hawk. (If you don’t have this app, get it. River Data provides on-demand access to cfs in select rivers throughout the US, and you can bookmark your favorite watersheds for fast reference.) Throughout the season, I eagerly anticipate rain events that will spike rivers — not too high, not too low. I’m looking for elevated river flows that introduce some amount of color to the water — not chocolate milk, but more like tea. This is when you can experience some of the best nymphing, and especially streamer action of the season. What’s more, water spikes shuffle the deck, move fish around, and provide a respite from warmer water temperatures.
You don’t need to wade very far from the shore. (In extreme cases, that may not be possible. Rules of thumb: never wade in water where you can’t see the bottom; never wade in water that you’re not very familiar with; never wade without a staff and spiked boots; never wade alone.) The fish, like you, aren’t interested in battling swift or raging currents. They’re close to shore, in pockets, behind structure, seeking the most moderate flows that will provide cover and food. In particular, I like to fish streamers in these conditions because the news gets even better: cfs and color spikes are when the big boys come out to play. These are often your best periods to up your chances of catching big fish, and sometimes multiple big fish. I like bigger flies, flies that create a commotion, and I will use both bright and dark colors, usually with equal success.
Use common sense. And enjoy!
