      I am looking for USACE surveys done in the Helena Valley in Montana. I believe there were some originally done when the irrigation canals were constructed, and I believe their were some done in the 1960s and 1980s in response to flooding. I am hoping to find them for some background information for a public meeting involving a flood mitigation district for Lewis and Clark County. Any help locating these would be greatly appreciated.
