Water Quality Sampling Results by SCWA at WQN211--Middletown PA, near the mouth of the Swatara Creek--where the Swatara empties into the Susquehanna River.
Water Quality: Over the years, due to its size, the Swatara Creek was impacted by a number of consumer and residential activities that contributed to an overall decline in water quality. As a result, a fixed sampling station known as WQN 211 (0352030) was established at the mouth of the Swatara Creek to monitor basin quality on a monthly basis.

Canoeists: In general, ideal
conditions are close to 2'. The further above two feet the Swatara rises,
the faster the ride--also increasing the danger factor. The further below
two feet the Swatara drops, the slower the ride, and the more times you'll have
to drag you canoe through shallow areas.
