The Incline Village monitoring site is located within the Lake Tahoe basin adjacent to Lakeshore Boulevard near Third Creek. This site was installed prior to the commencement of water year 2017. This site provides outfall characterization for an urban watershed that drains to a Third Creek, a tributary of Lake Tahoe. This reach of Third Creek is on Nevada’s 2014 303(d) List for pH and total phosphorus. This reach has also been listed in the past for dissolved oxygen and zinc. Lake Tahoe is an impaired water with TMDLs for: clarity, dissolved oxygen, plankton count, soluble phosphorus, and total soluble inorganic nitrogen.
The 97.8 acre catchment drains a relatively steep area of Incline Village with dominant urban land-uses consisting of higher density development including multi-family residential and commercial properties and a relatively large proportion of primary roads. Approximately forty-one percent of the catchment area is impervious and there is a lack of any intervening natural dispersion and infiltration areas. The monitoring station is located in the ditch that runs parallel to Lakeshore Boulevard shortly before it discharges into Third Creek. Improvements to the ditch are set to begin in 2017 and may include small basins to slow the flow rate and encourage infiltration and a rock-lining. Monitoring at the station began in October 2016.
Meteorological data is collected on the Sierra Nevada College campus approximately 0.4 miles from the Incline Village monitoring station and is representative of the overall catchment. The meteorological station is installed on the roof of the Tahoe Center for Environmental Sciences building.
