  • Limestone Stream — The Living River

    Limestone streams usually begin as underground systems, and because of that they are not as adversely affected by ambient temperature, as are freestone rivers. Their average year-round temperatures are 52 degrees F. Bank-side vegetation is of little consequence to maintaining stream temperatures or to the flow of energy, due to the large biomass of in-stream macrophytes.
