What is the difference between adult ladder counts starting March 15 and those starting January 1?
Starting in 2000 the Army Corp of Engineers began posting both direct observation and video counts on their website. Below is a table showing the dates for each type of observation. The COE previously had just reported the direct observation data starting March 15th, and therefore this is what is used in the ten-year average.If you are a fisherman and are just concerned with the number of fish passing each dam, then use the Counts Starting January 1st. Be aware that any of our reports or queries that use the ten-year average, such as the Cumulative Adult Passage Report that appears in our weekly report and the Adult Graph, use theCounts Starting March 15.
