In general, the response time to retrieve data using the data retrieval forms is measured in one-tenths of seconds to a few seconds (depending on the user's internet connection and how much data the user requested). However, we have observed that some browsers do not handle returns from cgi-bin programs very well. In particular, the IBM WebExplorer program version 1.01 does not. Versions 1 and 2 of the Netscape browser and various versions of the Mosaic browser for Unix systems both support cgi-bin programs. If you are able to navigate through our pages but when you hit the submit button in the data retrieval forms and your computer just sits there, chances are that your browser is having problems with the cgi-bin scripts. Unfortunately, there is nothing we can do to correct this issue. You will need to update your browser.
There is a bit of a disconnect between the inventory and what you can actually retrieve from the verified water level form. We will be adding improvements over the next several months to fix some of the problems. The inventory shows a list of data types and a range of data from the first record to the very last record, even if there are breaks in the middle. Also, not all of the data shown in the inventory may be verified. The verified water level form will only return verified data. If there is a mix of verified and unverified data in the time period requested, it returns nothing. So, the larger the time period requested, the more chance the user has of hitting some unverified data and getting nothing. We are working to resolve this problem.
