1 Watershed Assessment Section John Wirts Watershed Assessment Section March 17, 2009

2 Overview of monitoring activities Current and future monitoring Deployables, LiTMuS, and others Biology: bugs, fish, and algae

3 Watershed Branch Responsibilities Watershed Branch Responsibilities : §Statewide Monitoring Program l Ambient Monitoring of Major Rivers (26 sites, 6 times / year) l Random Monitoring of Wadeable Streams (1 st - 4 th order; 75 sites annually) §Watershed Specific Monitoring Program l General Water Quality Screening – Targeted (single visit) l TMDL Monitoring (monthly) §TMDL Development §Preparation of 305(b), 303(d) and Watershed Reports §Support of other agency programs (ie. Permitting) Monitor, Assess and Report on WVs Water Quality

9 AmbientMonitoringProgram Ambient Monitoring Program Monitor the states largest streams and rivers Currently 26 sites on the major rivers. bi-monthly samples for many parameters. Long term data - many have been monitored for nearly 50 years. Biology

10 Ambient Monitoring Program



13 Examples of available Ambient Data



16 Probabilistic, Targeted, and Pre-TMDL Sampling Include similar assessment procedures. Water Quality Field parameters, Fecal Coliform Others dependent on likely stressor Habitat Assessments Site maps, photos, & description Physical measurements Landuse activities and disturbances Qualitative habitat evaluations Biological Benthic macroinvertebrates Periphyton Fish

17 All Stations sampled or visited since 1996

18 Macroinvertebrates

19 Macroinvertebrates – Why? Resident biota in a watershed function as continual natural monitors of environmental quality, responding to the effects of both episodic as well as cumulative pollution and habitat alteration

20 Family Level Macroinvertebrate IBI WVSCI West Virginia Stream Condition Index Developed in 1999/2000 with EPA and Tetra Tech. Includes 6 metrics. Can be utilized statewide. Impairment threshold is based on reference conditions. Sampling period limited to the dates from which the reference condition was developed. Mid-April thru Mid-Oct

22 All comparable Benthic Macroinvertebrate samples since 1996

23 Probabilistic Sampling – Randoms Provides statistically valid estimates of condition. There are over 10,000 streams identified in WV. Between 30,000 and 50,000 stream miles. We cant sample them all.

24 Probabilistic Sampling - continued Started random program in 1997, completed 1 st round in Round 2: Changed from rotating basin to statewide approach. Instead of getting all 30 or 35 sites from a specific watershed in one year, were getting 5 or 6 samples in each of the 5 years. In April we will be starting year 3 of the 3 rd round

25 State of the Streams Report Data from 1 st 2 5-yr rounds has been crunched Condition estimates (% stream miles impacted) for: Biologically impaired Several habitat measures WQ condition estimates (acid precip, AMD, ++) Estimates completed for 8-dig HUC wsheds, Level 3 Ecoregions, and statewide Probabilistic Sampling - continued

26 Example of random data crunch

27 Round Three – entering 3 rd year of R3 Fewer sites (75/yr instead of 150) Will be able to report on condition at ecoregion level Will include fish at ~30 sites / year Probabilistic Sampling - continued

28 Sites selected within appropriate watersheds 4 main target categories: Representative sites: including major tributaries & HW Resample sites where use attainment questionable Refine impairment spatially: go upstream until above likely source Fill assessment Gaps TargetedMonitoring Targeted Monitoring

29 Monongahela Little Kanawha Upper & Lower New Greenbrier James & 2009 Targeted sampling 2009 – after random season

30 Mid-Ohio North & South Lower Guyandotte Tug Fork Gauley Potomac Direct Drains & 2008 & 2013 TMDL Sampling

31 Current Pre-TMDL sampling ~ 300 sites – starting July 2008 Sites sampled mostly for bacteria, biology, TSS, and Iron

32 ContinuousMonitoring Continuous Monitoring Have utilized in order to better understand relationship between grab samples and real world variability. Currently deployed in: Acid precip impacted streams Abandoned mining areas Potomac River sites Deployables

33 Acid Precipitation impacted sites / Limed Streams Project 2008 Added Otter Creek, Red Run

34 Abandoned Mine Land Remediation Monitoring Recently deployed sondes in Abram Creek, Three Forks Creek, and Paint Creek. Also Sovern Run of Big Sandy (Cheat)

35 Fish Tissue Analysis


37 Selenium - Fish & WQ studies Mercury Fish Tissue study LTMS – L I TM U S Lakes – Restarted in 2006 National Survey – streams, lakes, wetlands Wetlands

38 Above / below impoundment study Chesapeake Bay – Non-Tidal Monitoring Network Greenbrier algae / nutrient criteria development
