Meter Calibration Log
Scroll to yes or no to answer this question. If you use a pH or conductivity meter, enter calibration values. These fields do not allow text. If you have a comment or a problem calibrating, note this in the comments section.
This is a very important field to answer. Select Yes or No and list any expired supplies or any other supply needs.
The average dissolved oxygen (DO) is not calculated automatically. You must enter two values from different fixed sample bottles that are within 0.5mg/L of each other, as well as the average of the values. If the first two values are not within 0.5mg/L, enter the third titration run from the first of the previously fixed samples. If the range between the two fixed sample bottles was still more than 0.5mg/L, enter the fourth titration run on the remaining fixed sample bottle. If the results from the two fixed sample bottles are within 0.5mg/L average all values that are within 0.5mg/L. If the four readings from the two sample bottles are still greater than 0.5mg/L apart, do not average the results. Average to no more than two places past the decimal by rounding if necessary. Review the TST monitoring manual for more detail.
After entering the value, select if you used a comparator or meter to obtain the results.
Transparency Tube and Secchi Disk
Enter in meters. Don’t forget to enter =, Less Than <, or Greater Than >.
This is only collected by TST citizen scientists with advanced training; skip this section if you do not collect information on Nitrate Nitrogen. Select = or Less Than (<). Remember that this test’s detect limits are not sensitive enough to report =0; instead if there is no color change record the result as Less Than 1 (<1).
This is only collected by TST citizen scientists with advanced training; skip this section if you do not collect information on flow. Enter the value for CFS. Enter how value was determined (gauge site data or on site assessment) in the comments section.
You can simply enter the number for each field and then tab to advance to the next field.
- Flow Severity - Enter as dry or no flow if the water is nonexistent or too stagnant to monitor. Leave blank if site is on a lake or reservoir.
- Algae Cover - Be sure to assess both surface and substrate algae for the combined percent algae cover. Include additional information in the comments section if needed.
Considered cloudy if more than 10% of the sky is cloudy.
Days Since Last Significant Rainfall
Click here to view historical rainfall levels throughout the basin. Only enter numerical values such as: 3, 0, 2. Additional information such as 7+ or >10, will not be accepted. If it was raining while sampling, enter 0 for days since last significant rainfall, and record present weather as rain. Visit http://hydromet.lcra.org/ to view historical rainfall levels throughout the basin. If you are not sure, please estimate the number of days and explain in the comments section.
Inches of Rainfall

This is only collected by TST citizen scientists with advanced training; skip this section if you do not collect information on e.coli. Enter all the information as you would normally on the datasheet. If the value is TNTC, (too numerous to count), enter a value of 4000 and enter TNTC reference in the comments section. Average and round the result to the nearest whole number to remove decimals.
Two photographs may also be uploaded for each data sheet. Please rename the photograph SiteID_Date_Photo#.jpg. The photo must be 640px by 480px or smaller.
Nine fields are required to be completed before the data can be submitted.
- Site Name
- Sample Date
- Sample Time
- Sample Depth
- Total Depth
- Are reagents expired?
- Days since Last Significant Rainfall
- Minutes Sampling and Traveling
- Mile Traveled
- Number of Participants
How do I move from one section of the data sheet to the next?
Use the tab key to easily advance from one section to the next.
I’ve entered all my data, but I keep getting an error message. What do I do?
A yellow asterisk (*) indicates there is an error with the field entered. It is most likely that one of the key pieces of information has not been entered. Required fields are highlighted in red and must be completed before data can be submitted. Make sure that all required fields have been entered. Also, many of the fields only allow numerical values. If you need to explain a value, please do so in the comments section.
If my first two dissolved oxygen readings vary by more than 0.5mg/L, how should I average my data?
As a part of the CRWN quality control program two dissolved oxygen tests are run with each sampling trip. This means collecting and fixing two sample bottles and running two titrations, one from each bottle. If the values are within 0.5mg/L of each other, record the average of the two values. Average to no more than 2 places past the decimal. If the difference is greater than 0.5mg/L, run a third titration (steps 10-20) from the first of the previously fixed sample bottles. If the range between the two fixed sample bottles is 0.5mg/L or less, then record the average of all titrations within 0.5mg/L of each. (This could possibly be all three. Ex: sample 1=6.0mg/L sample 2=7.0 mg/L, sample 3=6.5 mg/L. In this case all three values should be averaged, resulting in 6.5mg/L.) If the range between the two fixed sample bottles is still more than 0.5mg/L, repeat the titration on the remaining sample bottle. If the range between the two fixed sample bottles is 0.5mg/L or less, record the average of all titrations within 0.5 mg/L of each other. If the readings from the two fixed sample bottles are still greater than 0.5mg/L apart, record the four values online, but do not enter the average
What should I do if my site is dry?
It is important to collect data from a site even if it is dry. Make sure to include all the required fields list above. Sample Depth and Total Depth would be 0.
How do I find rainfall data history for my site?
If you do not have access to a rain gage near your site, visit http://hydromet.lcra.org for rainfall information. Also try www.weatherbug.net for rainfall data in your area.
An error was encountered when entering days since last rainfall. How can this be corrected?
Please enter only numerical values for days since last significant rainfall. For example 7+, >10, or written comments will not be accepted. This information is very helpful though, so please feel free to expand on recent rainfall amounts in the comments section.
Visit http://hydromet.lcra.org/ to view historical rainfall levels throughout the basin.
If you are not sure please estimate the number of days and explain in the comments section.
What should I enter if it was raining while sampling?
If it is was raining while sampling, enter 0 for days since last significant rainfall, and indicate that it was raining in the present weather section.
The information I entered is gone and I received a timed-out notice. What should I do?
Since this is a password protected web interface, several minutes of inactivity will end your session automatically. This is to ensure the security of the system. The system did not enter your data sheet before it timed-out. You will need to enter the data again and submit the data sheet.
The website will not upload the photographs that I took at my site?
Currently, two pictures may be uploaded per data sheet.
We recommend naming your pictures SiteID_DatePhoto#.jpg for easier filing purposes.
The file size for pictures should be optimized for web viewing. Or the picture should be reduced to 640X480 size. Most photo viewing software will allow you to resize pictures.
When viewing the data sheet on my computer, the complete data sheet does not fit on the screen. What's wrong?
The online data form is best viewed at 1024x768 resolution or higher. If your computer screen is running 800x600 or less there will be horizontal scrolling.
