Important information regarding hydraulic models available on the DNR, Division of Ecological and Water Resources website.
The FIS, LOMR, Approximate and No-Rise models available on this website are, to the best of our knowledge, electronic copies of the input files to various modeling programs used to calculate the floodplain and floodway limits and water surface profiles for the respective Flood Insurance Studies.
However, the DNR does not guarantee these models to be the legal models for FEMA purposes. It is the user's responsibility to confirm that these models are the effective models for the FIS in question. Please refer to the FEMA website for information on how to obtain copies of this modeling. Dates of models listed and model extents shown are not guaranteed to be accurate. User must verify the model information. All models available may also not be listed, so the user should not assume that if a model is not shown, that it does not exist.
All models are provided "as is" without any kind of guarantee as to their accuracy or applicability for a particular purpose. Even though every effort is made to provide accurate information, the user assumes all risks concerning the suitability and accuracy of the model downloaded from this website. These models may contain technical inaccuracies or typographical errors. The State of Minnesota, Department of Natural Resources, Ecological and Water Resources Division assumes no responsibility for and disclaims all liability for any such errors in the models.
The DNR may make changes to these models at any time and without notice. We strive to have this modeling resource as complete and accurate as possible; any errors found in these models can be reported to the DNR by emailing Suzanne Jiwani. Staff can only provide limited assistance in interpretation or guidance regarding these models. For more information on the modeling process and DNR's requirements, we recommend you consult the Floodplain program.
