Water loss from Jordan Creek near Allentown, Pennsylvania - 1973 to 1976

Results of water-loss studies for Jordan Creek near Allentown, Pa. are presented in both tabular and graphical form. The reach studied is approximately 24 miles long and extends from a point near Lowhill, Pa. to a point in Allentown, Pa. The drainage area at Allentown is about 76 square miles. In portions of the study area, Jordan Creek loses considerable parts of its flow to the permeable limestones and dolomites that it traverses.

Seven current-meter measurements were made at each of ten sites along the reach, during the period 1973 to 1976. The results of the above measurements are analyzed and presented in a form suitable for use in planning the operation of a proposed reservoir which may be built near the upstream end of the reach.

Three examples of how the results may be used are presented.
