River Conditions in September

What does September mean to you?  Cooling temps?  Falling leaves?  Football?  Here in Durango it is what we know as a shoulder season.  A shoulder between the height of summer and winter.  Between the best summer dry fly fishing and powder skiing.  A time of year where our tourism drops off for a little while and things slow down.  For us it means a time to get out on the water with a lot less folks on the rivers.  Less tubers, less rafters, and less fisherman.  However, the fishing is still fantastic; and depending on where you are fishing, it can be the best time of year to be on the water.

Fortunately, the options for fishing will remain pretty vast in our little corner of the state.  Depending on the weather, the high country will continue to be a great option for getting into some wild fish.  The Animas is our most accessible local river and for good reason; it flows right through town.  The fall may be the best time to be out on the Animas as the big browns are on the move getting ready for their yearly spawn.  The San Juan will also continue to fish great without the summer crowds.  Other great options to consider are: The Piedra River, Los Pinos River, Dolores River, and San Miguel River.  Also keep in mind that big browns will be on the move from reservoirs into the rivers to spawn and will be looking for an easy meal in the mornings and evenings.

Keep in mind that Browns have a tough enough time spawning on their own without worrying about fisherman.  Please, we would ask that you leave any and all actively spawning fish alone.  They are more interested in propagating their species than eating.  It is very interesting to watch fish that are on the redds, but please keep walking and refrain from fishing to them.
