Preliminary results of organic geochemical and stable isotope analyses of Newark supergroup rocks in the Hartford and Newark basins, Eastern U.S.

Preliminary stage-discharge relations (limit curves) have been defined for Aliceville Lock and Dam covering the period February 1980 to May 1983 (Nelson and Ming, 1983). Subsequent data collected at the dam indicates a need for a revision to the preliminary curves. Due to channel instability in the vicinity, periodic review and possible update will be needed to keep the curves current. Using 48 data points defined by the flood of December 1983, the curves have been updated and are shown in this 1985 report. (USGS)
