Dominant Land Use:
This catchment is comprised of higher density development including multi-family residential and commercial properties and a relatively large proportion of primary roads.
Percentage of Impervious Surface:
46% percent of the catchment area is impervious.
The Incline Village monitoring site is located in the Wood Creek Watershed on the western edge of the parking lot for Incline Beach Park in Incline Village, Nevada. Runoff discharges directly to Lake Tahoe via a rock-lined ditch; the monitoring station is located in a culvert pipe directly upstream of the rock-lined ditch. This is the largest catchment in the monitoring network and contains the relatively steep, highly urbanized area of Incline Village, therefore this area has a high potential for generating fine sediment particles (FSP). Until 2016 there were numerous unarmored roadside ditches and bare shoulders used for parking that are known to contribute large amounts of sediment to runoff as well as a lack of any intervening natural dispersion and infiltration areas.
Washoe County completed an environmental improvement project in this catchment the summer of 2016. Improvements were made in the County right-of-way and on public properties and included sediment source controls such as slope, bare shoulder, parking, and channel stabilization. Improvements also included the installation of sediment traps throughout the project area to capture coarse sediments and the installation of a Contech Jellyfish vault above the existing monitoring site in an effort to capture FSP. Other water quality improvement strategies included various types of settlement and infiltration basins and the purchase of a high efficiency vacuum sweeper to remove a portion of the FSP generated on the roadways. This project was so successful that runoff volumes and FSP loads are now reduced to a third of what they used to be through capture, infiltration, and treatment. In October 2016 the monitoring site was moved down the street to a channel that parallels Lakeshore Blvd. and discharges into Third Creek.
