I'm sorry, but there is no Lake Powell in Florida. Lake Powell is actually located in Arizona and Utah. It is a popular destination for recreational activities including fishing, boating, and hiking. The lake is home to a variety of fish species including smallmouth and largemouth bass, striped bass, and catfish. The best time to fish at Lake Powell is during the spring and fall seasons when the temperatures are mild and the fish are more active. The average temperature during these seasons is around 70-80 degrees Fahrenheit. Nearby activities include kayaking, paddleboarding, and exploring the surrounding canyons and geological formations.
