The dewatered redd found on Feb. 20 was marked as a new redd on November 17th.
Estimated emergence for this redd based on 800 TU's is between January 21st (using egg pocket temperatures),
and March 8th using river water temperature plus 3 degrees Celcius.
Emergence at this redd, based on actual field observations, is estimated to have occured around February 15th or after 1000 TU's
using estimated egg pocket temperatures.
Estimated emergence dates for all chum redds were calibrated to reflect development through 1000 TU's .
