Project Update
- 5-14-07 PSMFC finished conducting the test run of the system over the weekend and made the announcement that the system was ready to be considered a production system.
- 5-8-07 - The COE conducted the final walk through for the project. This was done to create the punchlist of items that needed the contractors attention. There were only a handful of things that were presented and were to be addressed.
- 5-2-07PSMFC began installing the antennas in each shield.
- 4-25-07 - The weekly meeting was held at 1 p.m. there was a problem that was discovered the day prior with getting wire through the existing 2" conduit inside the JFF between the outside J-Box and the panel inside the PITtag room. The conduit appeared to be plugged and the possibility of new conduit having to be installed was to be decided. The electrician was going to try and clean out the conduit. The RF doors were not quite finished being installed but it was stated that they would be done by 4-27-07. A date of 5-8-07 was proclaimed as the day of the final walk through. PSMFC will be on site 5-2-07 to start the installation of the antennas and electronics.
- 4-10-07 - On site to inspect the modifications to the mounting structure. RF clamps are on site but not yet installed. The fiber and power distribution panel enclosure placement were moved to below the fourth shield. The doors have not yet been re-installed with the new hinges and the latches have not yet been installed.
- 4-2-07 - Visited the site to talk with electrician but not on site. A problem was discovered on the transceiver enclosure mounting structures. The opening was not wide enough to allow for the 30 X 30 enclosures. Modifications will be made to the structure per COE personnel.
- 3-28-07 - Meeting was brief. PSMFC addressed the issues of the RF clamps I.D. and increasing it to reflect an overall O.D. of 64.00" this was to allow for the uneven pipe circumference. PSMFC asked that the transceiver enclosures be hung so that the doors would swing downstream, this will help keep them open when the wind blows.
- 3-21-07 - There was no meeting today. The pipe was watered tested on 3-20-07 and all parties were on site during the water test. there was a slight leak that was detected on the upstream transition flange section but this was resolved by the contractor. It was discovered that the transceiver enclosure mounting structure was to wide for the locations that were originally called out (in front of the shields) so they were moved. Received a copy of all RFI issues.
- 3-13-07 - The weekly meeting for this week were canceled by COE personnel. The pipe install was completed on Friday 3-9-07. The water test was moved from 3-13-07 to 3-20-07. The site Biologist Terry Hurd stated that the water test will be conducted with makeup water and that the pipe will have water through the pipe starting April 2nd.
- 3/5/2007 - I started attending weekly meetings on 2/28/07. The pipe was delivered on 2/28/2007. I inspected the pipe for any abnormalities and did not find anything obvious. The shield were to be delivered in two stages, the first two shields would be delivered on 3/2/2007 with the remaining two delivered on 3/6/2007. PSMFC will be on site 3/7/2007 to inspect the shields and check to ensure that there is no continuity between the shields and the structure once they are in place. The meeting for 3/7/2007 was canceled by Naameh.
- 1/18/2007 - Pictures were taken by PSMFC show that the flume section has been removed.
- 1/10/2007 - Cisneros has built the scaffolding that will be necessary for their crew to work on the flume/pipe sections as they are installed.
- 12/06 - The contract was awarded to Cisneros Contruction. They will be mobilizing during the rest of the Moth of December.

RE: JOHN DAY FULL FLOW PIT INSTALLATION DECISION
Regional Fish Reps,
Per the message below the JD Full Flow PIT team is in the final stages of finishing our letter report that will recommend a primary site for the new John day Full Flow PIT Detection System. As of 3 May we had only received 2 comments back from Tom and Gary in regards to our current path both agreeing with the Corpsdirection and process. I have attached the Draft Final CH2MHill Decision Document that lays out our process thus far.The Corps JD FF PIT team will be meeting next week to finalize this document and we would liketheregional fish to respondto this requestin support of our recommendation.I would like to have e-mails of support or non-support back to me NLT Wednesday 14 June. A non-response will be seen as an agreement and concurrence with ourplan.
Thanks, -name removed-

Subject: RE: JOHN DAY FULL FLOW PIT INSTALLATION DECISION
Regional Fish Reps,
I have only had comments back from Gary Fredricks and Tom Lorz on this issue. They are both in favor of moving ahead with the current plan to get a FF PIT detector installed just above the switchgate area. They both also stated that we should continue the investigation into the viability of installing a system that could be operated during the winter but they don't want this requirement to slow the installation process. If you have comments please send them to me by the end of this week. Inthe next couple of weeksthe project development teamwill be finalizing our thoughts and making a recommendation.
Thanks,

Sorry for the first blank E-mail!
With that said, here is what I wanted to attach!
FFDRWG, SRWG, Regional Fish Managers,
As most of you are aware the Corps is in the initial stages of drafting a letter report to identify and locate the best suitable installation site for a full flow PIT detection system at JD. Attached is our meeting minutes from our site visit fromlast Tuesday with the in-house PDT players.The reason for this e-mail is to get clarity about the need to have year around FFPIT sampling capabilities at JDand to get comments back from the region about what it will take to accomplish this task and what the benefits would be if we were to pursue such a request.
During our site visit one area in particular rose to
the top as the best spot to locate a full flow PIT system. It is located
below the primary dewatering structure and just above the switch gate that
diverts fish either into the SMF or back to the return flume to the river.
At our first kick off meeting about this proposed project the subject of year
around monitoring came to light and identified the need
toinvestigatewinter passage of Fall Chinook or species that tend to
hold over in JD pool. By adding this requirement to our criteria,it
vastly complicatesthe system. Some of the hurdles andfar
reaching complications are as follows:
1. The Primary Dewatering Structure (PDS)was not designed to operate during winter months or freezing events. It is the team's opinion that a large amount of additional dollars will be needed to be added to the initialP&S effort as well as contract cost tomodify the current system. Significantdollars would be needed to enable the primary dewater structure to stay ice free during thewinter months (i.e.. modifying Screensweeps,dewatering pipes, auxiliary water systems, enclose the building, etc.)
2. Significant icing could take placein the corrugated flume sections of the JBS. Preventive measuresare likely to be costly.
3.Current operations of the system require OPS staff to be onsite 24 hours a day while the facility is inoperation.The currentschedule has OPs staffat the site from 1 April through 15 September each year. This is approximately 5 months. If we were to go to year around sampling Ops would have to cover an additional 7 or so months of 24 hour monitoring that is not scheduled or budgeted for.
4.Screens are currently removedon 15 December each year for theseason. Yeararound monitoring would require keeping screens in without much time for maintenance and redeployment.
Because of the obstacles outlined above there needs to be a regional discussion about the true need of year around monitoring and the associated biological benefits and outputs for management. I would like tohear from the regional fish managers as to their thoughtsand opinionsabout the need and benefits of this extra effort. If you can please e-mail withyour comments by COBFriday 28th April it would be appreciated. If you think that this subject and discussion warrants a Special FFDRWG meeting please respond to thateffect and I willgetsomething on the calendar in the near future.
This regional decision is extremely important and needs tobe made in the near future sothe Corps and the PDT team can continue tofast track this important program.
