Summary
When do trout spawn? A question from a reader who regularly walks along a trout stream not many miles from where I live. Trout spawn during winter, shedding their eggs into excavations in gravel. The eggs are then covered over to form the completed nest, known as a redd. Water percolates through the redd, bringing dissolved oxygen to the eggs, and to enable this to occur there must be little or no silt among the gravel or it will clog the pore spaces. A perfect spawning site is on the upstream face of a gravel bar where the current picks up speed.
In spring, emerging trout fry seek fairly shallow water which is slow flowing and with ample cover.See the full content of this document
