Check out the new and improved interactive CLAMP data set!

2017 Summer Science Teacher Externs Art Hellert (left), of Spirit Lake Middle School, and Marc Benedict (right) of Terril Graettinger Middle School,  have been working on analyzing CLAMP data this summer with Dennis Heimdal, Water Chemist at the State Hygienic Lab at Lakeside. The data set now goes back to the beginning of CLAMP in 1999! In addition, they have been working on plans to integrate CLAMP data into their classrooms and curriculums.

Happy CLAMPers!
Forty volunteers refreshed their water monitoring knowledge at 2016 CLAMP trainings and are now out on the water sampling! Follow our blog to learn about the data they are collecting.

2016 Trainings - Sign up Now!


Summer is just around the corner, and so is the 2016 lake monitoring season! Volunteers are needed to assist with checking the water quality of Dickinson County lakes with the Cooperative Lakes Area Monitoring Project coordinated by Iowa lakeside Laboratory. Free training and equipment are provided. To volunteer, all you need is access to a boat and to be able to donate about 12 hours of your time over the summer. Register for one of the workshops below or for more information, contact Jane Shuttleworth at or 712 337 3669 Ext 7.  Volunteers are especially needed for the smaller lakes: Center Lake, Little Spirit Lake and Silver Lake.

Free Trainings (registration required):

Friday, May 27 from 10:00 a.m. to noon or from 1:30 – 3:30 p.m.;

Saturday, May 28 from 10:00 to noon;

Successful CLAMP Trainings!

This past week at Lakeside there were 4 CLAMP training workshops. What a fun time learning how to retrieve data using secchi discs, YSI (Dissolved Oxygen) meters, and chlorophyll filtration. Now that we are pros we are ready for the real deal -sampling our Iowa Great Lakes! Thank you to everyone who was able to make it to the workshops.

West Okoboji Lake Water Quality Buoy

Last week Iowa Lakeside Laboratory deployed a limnological buoy in 98 ft of water on West Okoboji Lake.  Data is recorded every ten minutes by the buoy and can be viewed at the following link:   

Currently this buoy measures surface water temperature,  specific conductance, pH, dissolved oxygen, and carbon dioxide along with a number of weather related parameters.  Future plans are to measure water temperature and dissolved oxygen at every meter below the water surface.  Updates to the data site may change over time, so be on the look out for future posts regarding the buoy.

Be sure to check out all the sponsors at the bottom of the wqdata page who made this project possible.

A Beautiful Morning to Sample East Lake Okoboji!

This morning, August 7th, two CLAMPologists sampled East Okoboji Lake. The secchi readings between the five sights ranged from 1.25-2.25  meters. The temperature was around 24 degrees Celsius and the dissolved oxygen level ranged from 5.25-6.58 mg/L.
