REMARKS.--There is some regulation at low stage from mill operation. Canoe Creek Lake can influence flow, but any changes they make are rare/intermittant and are usually the result of the state park neeeding to perform maintenance on the dam.
COOPERATION.--Station established and maintained by the U.S. Geological Survey. Funding for the operation of this station is provided by the Pennsylvania Department of Environmental Protection and the U. S. Geological Survey.
REMARKS.--
The 15-minute precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
