Special Computations.-- <br />Remarks.-- <br />Recommendations.-- <br />Flume cleaning corrections are handled differently depending on whether it is the State or DWD perform the cleaning. If <br />the gage height drops as a result of a DWD flume cleaning, it usually occurs between measurements, it is Denver’s <br />procedure to increase the release so that the same gage height is maintained. A datum correction is applied to account for <br />the moss accumulation. Generally if the flume is cleaned by a State Hydrographer, a measurement is made before and <br />after the flume cleaning with shifts applied accordingly. <br />The record is considered good, except for July 20, 2010 which is estimated and poor due to missing data during the shelter <br />replacement, and a possible problem with the reference point in use. Station maintained and record developed by Mike <br />Wild. <br />Develop new rating. Install staff gage.
