This webcam is located at the USGS stream-gaging station on East Twin Creek near Arrowhead Springs (see map). This station was established in 1919 and provides continuous monitoring of certain river conditions such as flow and stage. The webcam provides valuable information to the National Weather Service, first-responders, and area residents to evaluate real-time conditions in the creek channel during storms. The visual record of flooding and potential debris flows also provides valuable research data for the USGS. This webcam installation is part of the USGS Multi-Hazards Demonstration Project.

Debris Flow Potential
Numerous fires have occurred in the East Twin Creek drainage area, most recently in 2003 and 2005. Because a significant proportion of the hillside vegetation was removed by fire, a record flood occurred in 2003 (see picture to the right). The location continues to be at high risk for such events.
