Population Estimate Methodology Change

Due to low re-capture rates in previous years, we decided to sample both the entire right and left bank of each one mile transect. These one mile sections where again separated by two mile non-sampled sections. Thanks to the higher water levels, this has been very successful, allowing us to get out 367 marks/11 recaptures in 2006 and 303 marks/11 recaptures in 2007.
