stage vs. discharge -relationship and obtain more reliable estimates of overbank flooding. Table 6. Estimated overbank flooding and frequency of flooding at the seven bottomland habitat sites in the Green River (GR). Overbank flooding was determined from staff vs. discharge relationships and river profiles conducted for each site in 1994. Flow percentile data for the post-water development period were taken from USGS stream gauging stations nearest the site.

The Little Stewart Lake, Baeser Bend, and Leota Pond 7 bottomland sites would flood between 18,000-22,000 cfs; one year out of ten. The Little Stewart Lake site has an old inlet ditch just upstream that could flood between 6,000-7,000 cfs every other year. Removal of about five feet of bank at the Baeser Bend site would allow flooding between 10,000-11,000 cfs every other year. The Johnson Pond 2 bottomland site would flood into the inlet ditch between 12,000-13,000, two years out of five. The Sheppard Bottom pond 3 site would flood into the inlet ditch between 7,000-8,000 cfs, seven years out of ten. The Woods Bottom site would flood into the inlet ditch between 2,000-4,000 cfs, nine out of 10 years. 35
