Avidfly and TylerW inspired me to make a couple of graphs that I hope stimulate more dsicussion of the crazy observations people have been reporting here this spring.
The first graph compares the average water temp at LD1 for the past 10 years with this year. The error bars represent a 95% confidence interval around the mean. The information in the graph suggests that fish are behaving as if it is the end of April instead of the end of March. Should we hold the Roundup next weekend?
The next graph compares the average daily flow from LD1 for the past 10 years to this year. Water flow through the dam is and has been significantly below average. The data presented below provides some evidence for why fish are in such odd locations now compared to normal. I wonder what effects such low water flow will have on the spawn and this year's generation of offspring?
