Lamprey Adult Data Lamprey Adult Data
- Adult lamprey data table Adult lamprey data table- Query for lamprey counts at the dam's adult fish ladders.
- Adult lamprey data graph Adult lamprey data graph- Graph adult lamprey counts at the dam's adult fish ladders.
- Adult lamprey incidental catch at SMP sites Adult incidental catch at SMP sites- Query for adult lamprey incidental data gathered at SMP sites.
- Lamprey count notes Lamprey count notes- Lamprey are active at night as well as the day. Adult lamprey counts at some fish ladders are video tapped during the evening hours and then reviewed later. The way in which counts are completed have changed over the years. For instance, at Rocky Reach Dam, from 1996 through 2007, there has been video monitoring 24 hours a day. From 1995 through 1992, there was direct monitoring for the adult counts at Rocky Reach Dam from 0400-2000. This means that caution should be used when comparing newer adult count data with older count data. To see an adult count data collection schedule for each dam click here.
