The Casselton Reservoir in Tinta Tawa Park is a small pond, and it serves as the park's centerpiece. The pond is stocked with fish and is open to non-motorized boat use. There is a path that circles the water that is great for walking laps or just ambling around with the family.
There is another paved path that circles around the northern baseball fields located on the property, so you can combine laps around the pond with laps around the fields when walking at Tinta Tawa Park.
