DEQ proposes to revise its Water Quality Standards, IDAPA 58.01.02, to modify the existing site-specific temperature criterion for the Snake River to protect fall spawning of Chinook salmon from Hell’s Canyon Dam to the Salmon River. This site-specific criterion would be a change from the current criterion of a maximum weekly maximum of 13°C from October 23rd through April 15th to a site-specific criterion of weekly maximum temperature (WMT) of 14.5°C from October 23rd through November 6th and a maximum WMT of 13°C from November 7th through April 15th. The first date a WMT can be calculated is October 29th.
The proposed rule change recognizes the declining thermal regime in the Snake River during the fall spawning season and that higher temperatures at the outset of the spawning season are both protective and supportive of the fall Chinook salmon spawning and incubation occurring in the Snake River during this time. This proposed rule change recognizes that a need to change the site-specific temperature criterion in the Snake River between the Hell’s Canyon Dam and the confluence with the Salmon River exists. The current site-specific criterion of 13°C between October 23rd and April 15th is not regularly met during the first 14 days of the fall spawning season and yet salmonid spawning and incubation are at the highest levels of the last two decades. The proposed rule changes the temperature criteria to 14.5°C for the first 14 days of the spawning period and then reduced to 13°C for the balance of the fall and early spring.
After consideration of public comments, the rule has been adopted as initially proposed.
