​​​​​​​Submitting Data for CBCW



What is CBCW Data and Where Does It Go?

​​Watercraft inspectors collect important data while conversing with boaters and anglers at the boat landings, such as the number of boats inspected, how long they spend at the boat landing, and how many people are contacted with the AIS prevention message. The information they record on their datasheets is entered into an online DNR database called SWIMS, which stands for Surface Water Integrated Monitoring System. All of the water data collected around the state by the DNR and its partners is entered into this database.

If you've already entered data before, or have already setup your SWIMS account, click the button above to enter the data you collected now.
If you are new to entering CBCW data, please see below for step-by-step instructions on how to set up your account and use SWIMS.​

How to Enter Clean Boats, Clean Waters Data​​​


Before you enter your CBCW data for the first time, you will need to set up a SWIMS account. To do this, you simply need to have an email address. You will then be able to select a user ID and password that you will use to access SWIMS.

How to Set-up a SWIMS Account

Once you follow all the steps to set up your SWIMS account, you will be ready to enter CBCW data. Log in to the SWIMS database using your selected user ID and password, and you will see your CBCW project listed along with options for entering data.

Data Entry Instructions

You can find some very helpful data reporting tips on the DNR's "CBCW: Reporting Your Data" webpage, such as how to add a boat landing to your project or how to report data for multiple inspectors who worked the same landing on the same day.
