Chalk Creek monitoring program: continuous

lynellg — Fri, 15 Feb 2008 15:29:22 -0800

An instream sonde probe meter collected WQ parameters including flow every 15 minutes from 3/21/07 - 4/29/08.

Chalk Creek monitoring program: weekly

lynellg — Fri, 15 Feb 2008 15:07:15 -0800

Weekly samples are taken on Chalk Creek at the constructed weir between Int. 80 and West Fourth Street, just west of Reno. New weir installed Winter 2008 is located above the Highland Ditch spillway.

Values less than the reporting limits are non-zero estimated values to simplify mathematical manipulation of the data. Minimum Test Reporting Limits (mg/l) are: Total-P 0.01, NH3-N 0.02, NO3-N + NO2-N 0.005, TKN 0.1, TSS 2, TDS 2. Any values given below these limits are estimates only, based on statistics.

NDEP Truckee River Project

lynellg — Fri, 15 Feb 2008 14:10:41 -0800

The NDEP Truckee River Monitoring project is sampled and tested by Desert Research Institute. The same methods have been used for the last 20 years. The Analytical Procedures table referenced the EPA methods. The Methods Summary attachment describes both EPA and Standard Methods (SM). The EPA and SM methods listed for each parameter are essentially equivalent from an analytical chemistry prospective, but the EPA versions include specific QA procedures. The EPA methods reference the SM methods (and sometimes vice versa).

Sampling sites can be viewed on the maps in the Maps and GIS section or at the website below. It may be a little hard to read the Site ID's on the Routine. We are no longer using the word Routine to describe the monthly sampling sites, but are now calling them Long Term sites. In the misc part we have two types of sites, short term and special studies.

Tahoe-Truckee Sanitation Agency (TTSA) - Martis Creek dataset

lynellg — Fri, 20 Jun 2008 12:30:38 -0700

The Tahoe-Truckee Sanitation Agency, or TTSA, is committed to a policy of energy and natural resource conservation. Our goal is to discharge the treated wastewater in the Truckee River Corridor in such a manner as to retain the integrity of ground and surface waters, while ensuring the quantity of water downstream is not diminished.

The Agency is committed to policy of conservation and recycle. A few examples are cited:
-The biological removal process substantially reduces chemical demands, energy, and landfill stresses.
-Anaerobic sludge digestion results in methane gas. This fuels boilers to provide building and process heat.
-Combustion offgases, principally carbon dioxide, is an integral component in pH control.

The TTSA is made up of five entities: Tahoe City PUD (530) 583-3796; North Tahoe PUD (530) 546-4212; Squaw Valley Public Service District (530) 583-4692; Alpine Springs County Water (530) 583-2342; Truckee Sanitary District (530) 587-3804.

Treated effluent is piped out through a soil aquifer treatment system through a series of laterals where physical, chemical and microbial activity improve water quality further. This large discharge field contains monitoring wells, which are monitored regularly. Effluent is retained within the system for a minimum of 50 days, then the aquifer emerges to the Truckee River or Martis Creek through seepage.

TMWRF benthic macroinvertebrate monitoring program

lynellg — Fri, 22 Aug 2008 13:02:41 -0700

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.
Replication as QA/QC: ?
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.
Habitat assessment: ?
Data Availability and Mode of Storage: TMWRF FoxPro database and hard copies of quarterly data for past 23 years.
Written protocols?
Purpose of monitoring: NPDES permit for TMWRF.

TMWRF River Monitoring Data: grab samples

lynellg — Mon, 07 Apr 2008 16:56:54 -0700

The TMWRF dataset contains continuous hourly SONDE data from various regular sampling sites along the Truckee River. Sampling locations, minimum reporting limits and analytical methods used are available in this metadata record.

TMWRF River Monitoring Data: Near-continuous

dwaetjen — Wed, 06 Feb 2008 09:39:15 -0800

The TMWRF dataset contains continuous hourly SONDE data from various sampling sites along the Truckee River. The SONDEs collect basic water quality parameters such as temperature, pH, cpecific conductivity and dissolved oxygen. Sampling locations, minimum reporting limits and analytical methods used are available in this metadata record.

Values less than the reporting limits are non-zero estimated values to simplify mathematical manipulation of the data.
