Discharge Tables

When using the discharge tables for the HS / H / HL Flumes it's important to remember that the tables are calculated to the top of the flume. This differs from the flow tables for most other flumes, where there is freeboard above the maximum head for the flume.  The Cutthroat Flume is the only other flume who's tables are calculated to the top of the flume.

In general, a freeboard of 1/6th the flume's depth should be allowed for when sizing a HS / H / HL Flume.
