Fish like bluegill, crappie, and largemouth bass live there. People love to fish, but there are rules. You can keep 10 bluegill a day. Bass between 14 and 18 inches must go back in the water. The lake has sandy edges and green plants. A 2.7-mile trail goes around it. The trail is not too hard and has nice views. You can see people kayaking or canoeing in summer. The water shows the sky and trees, making it a pretty place to sit.
