Estimated monthly percentile discharges at ungaged sites in the upper Yellowstone River Basin in Montana
Charles Parrett, J. A. Hull
1986, Water-Resources Investigations Report 86-4009
Once-monthly streamflow measurements were used to estimate selected percentile discharges on flow-duration curves of monthly mean discharge for 40 ungaged stream sites in the upper Yellowstone River basin in Montana. The estimation technique was a modification of the concurrent-discharge method previously described and used by H.C. Riggs to estimate annual...

Preliminary results of organic geochemical and stable isotope analyses of Newark supergroup rocks in the Hartford and Newark basins, Eastern U.S.
L.M. Pratt, A.K. Vuletich, C.A. Shaw
1986, Open-File Report 86-284
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...
