Boulder County hosts lake flood repair project open house Wednesday, July 31, in Longmont.

Lake 4, West Lake, & A-Frame Pond flood repair to begin in September.

Boulder County, Colo. - Boulder County Parks & Open Space and the St. Vrain and Left Hand Water Conservancy District will host a public information open house on Wednesday, July 31, in Longmont.

The county and the district will begin a flood recovery project to repair Lake 4, West Lake, and A-Frame Pond in early September 2019. The project is located on county property closed to public access just south of St. Vrain Creek between Highway 66 and Hygiene Road and west of Hygiene near 61st Street.

The project is necessary due to the extensive damage caused by the 2013 flood. The project includes repair to the breached embankments and the construction of new emergency spillways that will better protect the area in future flood events. The project is expected to continue through July 2020.
