Typically, the Colorado Division of Water Resources is very helpful in facilitating water well permit application, reasonable review, and prompt approval. Sometimes they require information beyond that immediately available to the applicant. In such instances, Guide Water can help, whether you seek a permit to drill a new well, to use an existing well, or to modify or replace an existing permit.
If planning work involving placement of material in any waterway under the jurisdiction of the United States Army Corps of Engineers, it is a good idea to notify them, and if necessary, to comply with conditions of their verification that the project conforms with a Department of the Army permit. It might be beneficial to ask Guide Water to facilitate the process. For this or other permit support, make contact.
