Olathe Lake water depth. I understand that the park there will soon be posting this online as well. More detailed images are available (I had to downsize these to be able to post them). A website with the detailed maps will be up soon, along with maps that will have a GPS grid superimposed on the depth map. The Kansas Biological Survey is in the process of surveying a number of Kansas lakes and reservoirs for water depth and bottom type classification. These maps will be made available online as they are produced. Questions and comments may be addressed to the project director, Mark Jakubauskas, at the Kansas Biological Survey, at email@example.com or 785-864-1508.
