Just wondering if any of you are involved in tile line monitoring on farms and if so, I’d be interested in learning what methods you follow, particularly for flow monitoring, but also other parameters as well.

Kris, All–

I’ve responded to the whole list as there may be others who would find this
resource helpful.

Our Michigan CAFO staff Sentinel Lynn Henning has done extensive monitoring
of tile systems, much of it around mega-dairies. She has more knowledge
about tile systems, their operation, and monitoring them than anyone else
I’m aware of in the US.

Lynn would be happy to field any questions on the topic. Contact her off
listserv at:

Hi Kris,
I do things very cheaply. To measure water from tile I use gallon jugs, or bags, and time it for 10 seconds and multiply to get gallons per minute (or you can weigh it) Also I was taught to use a ruler and use a leaf and drop it at one end of the ruler and time how long it takes to reach the other end of the ruler.( this will give you the speed such as 1 foot per 5 seconds to show the speed) I also take digital pictures to show how much water is coming from the tile. You can also measure speed of the water with your camera if you have time and date and measure the location you take the picture of)
I mainly use a DO meter. For my work I take pictures of the tile at least three days a week to show flow, color. I get many discharges just before large predicted rainfalls. Just by taking pictures with time and date we have gotten enforcement from the agencies.

Sorry to be chiming in a little late — but just want to mention there is an
article in the Winter 2006 Volunteer Monitor newsletter
about volunteers with the Michigan Sierra Club Water Sentinels Project
monitoring CAFOs for E. coli. See the article “Monitoring Water Pollution
from CAFOs” by Rita Jack, starting on page 19.
