Section 2: Financial Information/Budget for Rescheduled Activities
Original Budget for Rescheduled Activities FY 2007: $664,078
Proposed Budget for Rescheduled Activities FY 2008: $435,794
Explanation or Additional Information: This request is to reschedule funds from FY08 to FY09 for BPA project 2002032. This relates to contracts 36373 (USGS), 26934 Rel 13 (PNNL), and 36748 (UW).

In FY08, we intended to radio and acoustic tag run-of-the-river subyearling fall Chinook salmon in the Clearwater River. Fish collected from the river were found to be compromised by gas bubble trauma (GBT). Initial attempts to tag fish resulted in excessive mortality (~50%). Typical mortality from tagging is 0-1%. Regular sampling of fish revealed that fish exhibited GBT through the end of August—past our window of opportunity to tag fish. Elevated gas levels in the Clearwater River precluded all tagging activities during the summer of 2008. Personnel of project 2002032 decided it would be best save already-purchased radio tags for use in FY09. Similarly, vendors were contacted to stop production on most acoustic tags in 2008 with the intent of resuming production in FY09. We are requesting that funds associated with tagging, data collection, and data analysis work elements be rescheduled from FY08 to FY09. This will allow us to increase our sample sizes and effort in 2009 to provide more certainty for our results and inferences. Because this project was funded at a level far lower than originally requested, it has suffered from low sample sizes and effort. This reschedule will help ameliorate this shortcoming.

At present, we believe that spill at Dworshak Dam was partially responsible for elevated gas levels observed in the Clearwater River in 2008. Because gas levels were not excessively high (e.g., >110%), chronic low levels of gas may be a common occurrence in the Clearwater River. To overcome this in 2009, we plan to set up pumps, tanks, and stripping columns at the Hog Island tagging site. Fish will be collected from the river and held in tanks of degassed water to allow symptoms of GBT to dissipate before tagging. Preliminary testing has shown this approach will be effective as solving GBT-related problems.

The original budget and the proposed budget for the rescheduled tasks do not match for the following reasons. Some work was conducted on these tasks in 2008 in anticipation of planned data collection. For example, all telemetry data collection gear was installed and tested prior to the scheduled release of tagged. This equipment needed to be retrieved as well. One release of tagged fish was made in June in the Snake River and funds were expended to tag, track, download receivers, and analyze subsequent data. Funds were also expended to collect and tag fish in the Clearwater River before the magnitude of GBT-related problems were realized and activities halted. ATS produced about half of the acoustic tags before production was stopped. Projects were still needed management in spite of not conducting all planned work.


Section 3: Financial Information/Budget for Rescheduled Activities
Activity Description Original Start Date Original End Date New Start Date New End Date Condition/Situation Creating the Need to Reschedule Cost What Will Enable the Work to be Achieved Now?
USGS WE 158 Mark/Tag Animals: Wild juvenile fall chinook salmon will be tagged with either 0.42 and 0.85 g radio tags and a PIT tag  4/1/2008  10/15/2008  7/1/2009  9/15/2009  In 2008, elevated total dissolved gas levels in the Clearwater River caused fish to exhibit GBT and precluded tagging due to excessive mortality.  $48,000  In 2009, degassing tanks and columns will be set up to allow captured fish to dissipate any gas in their bodies before being tagged. 
USGS WE 157 Collect Data: To estimate detection probabilities of radio-tagged fish, it will be necessary to confirm tag life. We will activate a sample of radio tags and let them run until they expire to confirm the mean tag life.  4/1/2008  12/15/2008  7/1/2009  12/15/2009  See previous response. Since tags will be held for use in 2009, it will be necessary to conduct tag-life tests then to determine how much battery life has decreased.  $12,000  Tests will be conducted to confirm the life of tags that will be saved and implanted in fish in 2009 
USGS WE 157 Collect Data: Download data from radio telemetry receivers to determine the migration rate between each detection site and identify where fish delay their migration.  4/1/2008  12/15/2008  7/1/2009  12/15/2009  See previous response. No data collected on fish from the Clearwater River in 2008.  $1,000  The same detection data scheduled to be collected in 2008 will be collected in 2009. 
USGS WE 157 Collect Data: Tagged fish will be mobile tracked by boat three days a week to identify where fish delay their migration within the study area, and will provide mark-recapture information for abundance estimation and fate.  4/1/2008  3/31/2009  7/1/2009  12/15/2009  See previous response. No fish were tagged and mobile tracked in 2008 due to GBT issues  $3,452  The same mobile tracking effort scheduled for 2009 will also collect data on fish tagged with 2008 tags. 
USGS WE 162 Analyze Data: Construct a detection history for each fish. Identify variables that affect migration timing, rate, and potential delay and overwintering.  12/1/2008  3/31/2009  12/1/2009  3/31/2010  See previous response. No data collected on fish from the Clearwater River in 2008 that can be analyzed  $4,000  The same analyses of 2009 data will be conducted concurrently for rescheduled 2008 data. 
UW WE 162 Analyze/Interpret Data: Assist in analyzing RT, AT, and PIT-tag data. Relate migrational behavior to environmental conditions.   10/1/2008  3/31/2009  10/1/2009  3/31/2010  See previous response. No fish were tagged and mobile tracked in 2008 due to GBT issues.  $8,031  The same analyses of 2009 data will be conducted concurrently for rescheduled 2008 data. 
UW WE 162 Analyze/Interpret Data: Develop alternative methods to calculate SAR, based on additional AT, RT, and PIT-tag data collected in FY08.  7/1/2008  3/31/2009  7/1/2009  3/31/2010  previous response. No fish were tagged and mobile tracked in 2008 due to GBT issues.  $4,851  The same analyses of 2009 data will be conducted concurrently for rescheduled 2008 data. 
PNNL WE 70 Install Fish Monitoring Equipment: Deploy Acoustic Telemetry Equipment  5/15/2008  8/1/2008  5/15/2009  8/15/2009  In 2008, acoustic receiving nodes were not deployed because fish were not tagged (see above). In 2009, up to 8 additional receivers may be deployed to take advantage of the increased fish sample size and improve resolution of behavioral data.  $20,000  The 10 nodes that were originally to be deployed in 2008 will be deployed in 2009 as well as additional nodes  
PNNL WE 158 Mark/Tag Animals: Tag fish with JSATS acoustic transmitters  5/15/2008  11/1/2008  7/1/2009  9/15/2009  See explanation above for USGS WE 158. Gas bubble trauma precluded tagging due to high mortality  $100,000  See explanation above for USGS WE 158.  
PNNL WE 157 Collect/Generate/Validate Field and Lab Data: Download acoustic telemetry gear  5/28/2008  3/28/2009  7/1/2009  3/28/2010  See explanations above. No fish were acoustic-tagged in 2008. An increase in the number of acoustic nodes will increase the effort required.  $100,000  The same data to be collected in 2008/09 will be collected in 2009/10. 
PNNL WE 162: Analyze/Interpret Data: Compile AT Detection data  2/28/2009  3/31/2009  2/28/2010  3/31/2010  See explanation above. No data were collected in 2008 because no fish were tagged.  $50,000  The same data processing to be conducted in 2009 will be conducted in 2010. 
PNNL WE: Manage Project  4/1/2008  3/31/2009  4/1/2009  3/31/2010  An increase in the number of acoustic nodes and additional planning needed for a larger tagging operation will require more management duties.  $20,000  Rescheduled funds will be used for increased management duties in 2010 due to more tagging and data collection. 
ATS WE 158: Produce acoustic tags  4/1/2008  9/30/2008  4/1/2009  9/30/2009  Tag production stopped to produce tags with longer battery life in 2009  $64,460  Tag production will be resumed in 2009 

Please explain why the following alternative funding solutions are not feasible and would jeopardize the project:
Reducing existing scope of project
(i.e., eliminating some activities planned for FY 2008 to accommodate the FY 2007 activities)
In FY08, we intended to radio and acoustic tag run-of-the-river subyearling fall Chinook salmon in the Clearwater River. Fish collected from the river were found to be compromised by gas bubble trauma (GBT). Initial attempts to tag fish resulted in excessive mortality (~50%). Typical mortality from tagging is 0-1%. Regular sampling of fish revealed that fish exhibited GBT through the end of August—past our window of opportunity to tag fish. Elevated gas levels in the Clearwater River precluded all tagging activities during the summer of 2008. Personnel of project 2002032 decided it would be best save already-purchased radio tags for use in FY09. Similarly, vendors were contacted to stop production on most acoustic tags in 2008 with the intent of resuming production in FY09. We are requesting that funds associated with tagging, data collection, and data analysis work elements be rescheduled from FY08 to FY09. This will allow us to increase our sample sizes and effort in 2009 to provide more certainty for our results and inferences. Because this project was funded at a level far lower than originally requested, it has suffered from low sample sizes and effort. This reschedule will help ameliorate this shortcoming.

At present, we believe that spill at Dworshak Dam was partially responsible for elevated gas levels observed in the Clearwater River in 2008. Because gas levels were not excessively high (e.g., >110%), chronic low levels of gas may be a common occurrence in the Clearwater River.

Fish will be collected from the river and held in tanks of degassed water to allow symptoms of GBT to dissipate before tagging. Preliminary testing has shown this approach will be effective as solving GBT-related problems.

Shifting entire schedule
(i.e., deferring some FY 2008 activities to FY 2009 to avoid doubling up on activities this year)
Shifting the 2009 work into 2010 in order to complete the 2008 work in 2009 will not be possible since this project is not currently funded for 2010. The same work that was scheduled to be completed in 2008 is also scheduled for 2009. The 2008 work will be “piggybacked” on the 2009 work and will not jeopardize completing all work. This will be an efficient approach since the work planned for the two years is the same. For example, the detection equipment deployed in 2009 will acquire data on both 2008 and 2009 tags. Similarly, analysis of 2009 data will be the same as for rescheduled 2008 data. A significant advantage to this rescheduling is an increase in sample sizes in the 2009 data set.
