The following areas are known to have good supplies of oxygen and therefore are great for fly fishing:

• Creek mouths. There is a constant flow of water here that will have high levels of oxygen.
• Rivers. Again, there will be the constant flow of water present in most rivers.
• Areas of vegetation. Aquatic plants need a steady supply of oxygen to keep them alive and thriving.
• In deep water. Deeper water is usually colder than higher water. Therefore there will be a better supply of oxygen.
• Near power plants. There will be a continuous discharge of oxygenic water near power plants.
• Near tree and log areas. Oxygen is present in treed areas because porous wood will hold oxygen.

Keep some clear (or possibly colored) fingernail polish in your tackle box for quick repairs on flys. Sometimes a fly will begin to unravel, or get a little raggy. You can repair this easily with a little fingernail polish, or some of that super glue. Problem with the super glue is it will often dry up on you once you open the little tube. Nail polish will keep for a long time.
