Year  Year as specified in the query. 
Project  Project as specified in the query. 
River Parameter  River Parameter as specified in the query. 
Critical Value  Critical Value or range of Critical Values as specified in the query. 
Calculate Exposure  Below Critical Value: Calculate the percent of fish exposed to values below the selected Critical Value for the selected River Parameter. Above Critical Value: Calculate the percent of fish exposed to values above the selected Critical Value for the selected River Parameter. Range Critical Value: Calculate the percent of fish exposed to values within the range of Critical Values for the selected River Parameter. 
Fill Missing River Data  Yes: Apply simple data interpolation to fill missing data points within the River Parameter data set. These filled values will be used in calculations for fish exposure and averages. No: Use River Parameter data set as found in DART. 
The Total Run Period is defined by the first date when fish are observed/transported to the last date when fish are observed/transported at the selected Project within the selected Start and End dates. The values for Start Date and End Date specified in the query determine the maximum length of the run period. The Total Run Period may not reflect the true run period.
Total Number of Fish Observed/Transported  Total number of fish observed/transported during the Total Run period. In the case of Transport queries, this is the total number of fish transported (the sum of the number of fish barged and trucked from the project). 
Percent of Total Run Analyzed [Number Observed/Transported]  Percent of the total number of fish observed/transported that qualify to be analyzed (the number of fish analyzed follows in square brackets). In order for observed/transported fish to be included in the analysis, River Parameter data must be available for the same day. If River Parameter data is unavailable/missing for any day during the Total Run Period, then the number of fish analyzed is less than the number of fish observed/transported. 
Exposure Index 

Total Percent Fish Exposed [Number Exposed] 
The number of fish exposed divided by the Total Number of Fish Analyzed observed/transported at the Project during the Total Run Period. The number of fish exposed follows in square brackets.
The Number Exposed is based on the query specification for whether exposure is calculated below the Critical Value, above the Critical Value or within a range of Critical Values.

Number of Days Fish Exposed  Total number of days when fish are observed/transported at the Project and the River Parameter value observed matches the critical value conditions as defined in the number of fish exposed. 
The Middle 80% of the Run is defined by a range of days rather than an exact percent of the run. The Middle 80% of the Run Period begins on the first day when the percent of fish observed/transported at the Project is greater than or equal to 10%. The Middle 80% of the Run Period ends on the first day when the percent of fish observed/transported at the Project is greater than or equal to 90%. In some cases, the percent of the run passing during this period can be well above 80%.
Number of Fish Observed/Transported  The total number of fish observed/transported at the selected Project during the Middle 80% of the Run Period. 
Percent of Middle 80% of Run Analyzed [Number Observed/Transported]  Percent of the total number of fish observed/transported during the Middle 80% of the Run Period that qualify to be analyzed (the number of fish analyzed follows in square brackets). In order for observed/transported fish to be included in the analysis, River Parameter data must be available for the same day. If River Parameter data is unavailable/missing for any day during the Middle 80% of the Run Period, then the number of fish analyzed is less than the number of fish observed/transported. 
Exposure Index 

Percent Fish Exposed [Number Exposed] 
The number of fish exposed divided by the Number of Fish Analyzed observed/transported at the Project during the Middle 80% of the Run period. The number of fish exposed during the Middle 80% of the Run period follows in square brackets.
The Number Exposed is based on the query specification for whether exposure is calculated below the Critical Value, above the Critical Value or within a range of Critical Values.

Number of Days Fish Exposed  The number of days during the Middle 80% of the Run period when fish are observed/transported at the Project and the River Parameter value observed matches the critical value conditions as defined in the number of fish exposed. 
Run Dates are based on the Total Run Period of the query. The Total Run Period may not reflect the true run period.
First Day of Run  Date of the first day of the run. 
5% of Run passed  Date when the percent of fish passing the Project is greater than or equal to 5%. 
10% of Run passed  Date when the percent of fish passing the Project is greater than or equal to 10%. 
50% of Run passed  Date when the percent of fish passing the Project is greater than or equal to 50%. 
90% of Run passed  Date when the percent of fish passing the Project is greater than or equal to 90%. 
95% of Run passed  Date when the percent of fish passing the Project is greater than or equal to 95%. 
Last Day of Run  Date of the last day of the run. 
For a single Critical Value, the dates when the observed value for the River Parameter is equal to the Critical Value, and dates when the observed value for the River Parameter crosses below or above the Critical Value line. For a range of Critical Values, the dates when the observed value for the River Parameter crosses inside or outside of the specified Critical Value range.
