Grab samples are currently taken at various locations on the Truckee River mainstem and tributaries including North Truckee Drain and Steamboat Creek. River sample locations are: East McCarran Bridge, Lockwood, Tracy/Old Clark Bridge, Derby Dam, Painted Rock, Wadsworth (really Dead Ox), and Nixon.
Specific Locations include the following:
#3 at East McCarren bridge, grabs taken on the downstream side of bridge. 39 deg/ 31'02" x 119 deg 44'23"
#4 Below Lockwood at the old bridge for grab samples, taken downstream of bridge. 39 deg/ 30'33" x 119 deg 38'58"
#5 Old Clark bridge at USA Parkway, grabs taken on the downstream side of bridge. 39 deg. 33'80" x 119 deg 29'29"
#7 Dead Ox, benthic sampling only 39 deg. 44'44" x 119 deg 19'20" (permit states Wadsworth but site was switched possibly due to safety concerns, over 8 years ago).
This Lake Tahoe Data Clearinghouse website, created and maintained by the footer image. U.S. Geological Survey (USGS) in partnership with Federal, State, tribal, and local agencies and groups, is a gateway to information and data on Lake Tahoe and its basin.
Equipment used: Hess sampler with 500 mesh netting. Area sampled: 0.256 m2 per sample, and three replicate samples are taken at each site. Subsampling: approx. 10-15% of samples must be halved due to richness, but counts over 200 are maintained whenever possible. Taxonomic level: to genus and species, except for Diptera chironomids, which are identified to subfamily or tribe level. Oligochaetes are identified to family level.
QA: Type specimens are confirmed by Idaho State University, Stream Ecology Center; Type specimen collection established and archived to demonstrate past id's and for future verification of specimens. Library of general and taxon specific texts and monographs for sample handling, collection and identification. Bibliography of texts, keys, monographs, etc. are available.
Analysis/metrics: Idenfication and enumeration of invertebrates and invertebrate biomass determinations. No metrics are applied.
