Attached is my summary of preliminary comments on the draft MFL. It is subject to modification as I continue to read the reports.

Thanks Peter.  For today's meeting, I think that we should briefly summarize our comments so that the District staff will know what are comments that might require a simple correction, and what are comments that may need them to spend additional time on.  For example, we don't have to review typos with them today, but I think that we could point out what are concerns that they should focus on, given the timeline for this report.  I'll start off, and then if you want to go next Peter, and then Laura, if she has comments ready, or just wants to talk through her initial thoughts on the draft MFL.

Yes, sounds good, Dave. I will post a quick summary of my initial thoughts before the meeting. I read both of your (yours and Peter's) posted documents and had some of the same points. I made some notes on those and the main report and appendices. One thing I would like to talk about the fish population modeling work and its source data (Appendix E).

Sounds good, Dave. Talk to you and Laura soon.

Here are some initial thoughts and comments. I focused more on the ecology and water quality areas in these.

Laura:  Thanks!  After intro from Doug, are you guys okay with me going through my comments first, and then perhaps Laura, and then Peter.  Chair, then alphabetical?  I think that our goal here is not to get an answer to everything, but we've given the District a rough outline of our comments, so that they can come back at the next meeting with responses.  this should cut back on the time needed for producing our initial draft report.

Written comments e-mailed to Doug Leeper by Angel Martin on April 13, 2020, based on his oral comments provided during the April 13, 2020 peer review panel teleconference.

<><><><><>
As per the discussion concerning the subject peer review panel teleconference for the Lower Peace
River and Lower Shell Creek, the following are my comments/suggestions for consideration that I
briefly discussed.

1. Concerning the stratification of freshwater/saltwater in the open waters of Charlotte Bay,
Mr. Tomasko clearly answered my questions and described the processes involved when a
large volume of freshwater is discharged to the bay. I suggest that the two reports that Mr.
Tomasko referred to be included in the final report.

2. Suggest further discussion of the base flow component determined with the modeling and
how reasonable is this component when compared to other available information.

3. Suggest adding some discussion in the final report (a paragraph or two) on model limitation
and uncertainty (as discussed by Mr. Sheng) and which parameters may be more uncertain
for developing minimum flows and levels.

4. Suggest adding a section on possible future data collection and updating the analysis and
models. For example, perhaps additional vegetation data are needed. Also, there are
locations where tributaries may require gaging for better model simulation and analysis.
Additional data may be required to reduce model uncertainty as discussed in item 3 above.
As mentioned during the teleconference by others, the analysis should be reviewed on a
regular and systematic basis. As additional data are collected and analyzed, the models
should be updated and revised and the minimum flows and levels adjusted, if warranted.

I appreciate being able to comment on this important work. Please contact me if you need any
additional information or clarification.

Angel Martin

Draft summary of the April 13, 2020 Lower Peace River/Lower Shell Creek minimum flows peer review panel teleconference is attached. Draft was prepared and reviewed by Doug Leeper and Dave Tomasko. Once reviewed/revised/approved by Lara Bedinger and Peter Sheng (and Doug Leeper and Dave Tomasko if changes are made) a final version of the summary will be posted to the webforum. Approval can occur through the webforum or during the panel's teleconference scheduled for 4/20/2020.

Final summary of the April 13, 2020 Lower Peace River/Lower Shell Creek minimum flows peer review panel teleconference is attached. Differences between the attached file and the draft summary include correction of the start time for the teleconference and the correction of a few typographical and grammatical errors.

Doug:

Found what appears to be an error in the MFL report - at least something worth looking into.  Figure 6-3 and the text associated with that figure refers to the reference system of Charlie Creek, and the reference time period of 1950 to 1969.  However, it does not appear that the USGS flow data are available for the entirety of 1950 - at least the flow data on the USGS web site.  The earliest first year with flows for each month is 1951, not 1950.  Two things - either the District used an incomplete 1950 data set for flows, or it used 1951 for flows, and the figure legend should be modified.  Won't be a huge difference, but something I just found out - looking at the data set for Charlie Creek for other purposes.

Reply to 4/30/2020 post by David Tomakso regarding presentation of Charlie Creek flows:

Thanks, Dave. We will look into this issue and address any concerns regarding presentation of the Charlie Creek flow record in Figure 5-3 and the text associated with that figure in the next draft version of the District's minimum flows report.
