Resharing an oldie, but a goodie, post from our friends at Iowa Driftless Chapter of Trout Unlimited.
Fall is an important time for our native brook trout and wild brown trout as they begin spawning in local streams. During this time, trout create nests called redds, where they lay and protect their eggs.
Redds are areas of cleaned gravel on the stream bottom and often appear noticeably lighter in color than the surrounding streambed. You'll typically find them in shallow, faster-moving sections of streams with gravel bottoms.
Walking through these areas can disturb or damage trout eggs. As the season progresses, redds can become harder to spot, so it's important to take note of their locations and avoid them.
Trout eggs won't hatch until February or March, making it especially important to protect these nesting areas throughout the winter.
If you're unsure whether an area is a redd, play it safe and stay out of the stream!
