These levels and their cautions are of my own opinion. I have been wade fishing, canoe & kayaking, the Kish for 50+ years. I am a blinded, United States veteran (USMC), with failing eyesight, so learning about and knowing the levels was important to me. I kept a 10 year record log on this section of the river and designed a, personal comfort, caution chart to help me decide whether or not I should wade fish? Kayak fish? Which branch might be best? Or even which stretch might be best? BE SAFE! ~Terry Dodge
