The overall effect of all non-hydrologic effects remains a small negative impact on summer low flows which will need to be addressed as part of a proposed low flow mitigation plan. I asked how the relinquishment of water withdrawals would be handled in the low flow analysis, in terms of assumed timing of the water withdrawals. I still suspect the numbers are more representative of withdrawal rates which would be sustained for a few hours per day, and probably not everyday of the week. The indication was that it was up to Joe Brascher as to how to incorporate the water withdrawal table into the low-flow impact. Therefore, I have no idea how this will be performed. f also do not fully understand the logic behind the "non-respondents" to the survey. It appears that a much larger percentage of the non-respondents were assumed to have been withdrawing water than would be indicated by the trend set…
