I received a special report from Ken's sporting goods." It sounds like the Reservoir is in the process of "turning over" and this created a huge amount of carbon dioxide from the decaying weeds and as the carbon dioxide pushed through the dam at the "Big Hole" it caused a significant fish kill. We've had reports and photos of many fish, hundreds if not thousands of fish of all species, dead along the "Mile". It's too soon to really know the extent of the die off but it appears to be significant. Some of these fish may have actually come from the Reservoir but it seems likely that most of them are from the river. We've only had a few reports from anglers fishing the Mile after the event and all have reported not getting any fish or even any takes. My understanding is that this situation occurs every year as the weeds and algae in the Reservoir start to die off and decay but typically it is not anywhere as intense as it was this time, we often see a die off of small perch in the river around this time of the year which is likely caused by the same thing, it's usually just not as huge an event as it was this time".
