Water Quality Sampling Results by SWA 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.

USGS Guages (Pine Grove, Inwood, Harper's Tavern, Hershey) provide additional data on the Swatara Creek.  Depth in Real Time.  Or, click on a map http://www.erh.noaa.gov/marfc/

Canoeists:  Thinking about a float today?  Check water depth Swatara River PageGuidelines:  If Harper’s USGS gauge is rising from 3.5 toward 4', water is too high even for experienced paddlers to launch; if below .3’ at Harper's, water is too low to launch.  Beginners should not launch if Swatara is over 2.6'.  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.  Kayaks can clear more areas than canoes.  

At Swatara Watershed Park, 1929 Blacks Bridge Road, Annville, when Harpers gauge reads:
