I have lived on the water on Chickamauga for the last 17 years and in most years the water is brought from winter pool to summer pool over the first two weeks of April. I know that the guide shows that May 15th is the target but in most years they only give it two weeks. With the rains that we are expected to have it could be that the water will be up early but TVA could decide that they want to only bring it up slowly or they may let it come up and then bring it back down and let it come up slowly. If the water temp is 60-65 when the next full moon comes around, and that should be the 20th I would expect the crappie to spawn. If it's a bit warmer, the bass will spawn. If TVA brings the water down some after that it might be a bad spawning year. I watch for this most every year but usually the water is up and stays up after the 15th. Some years the water is a bit warmer and it's more of an issue. I don't expect that the bass will spawn much this go round unless we get some really warm rain or lots of sunshine.
