Abstract:
One of the main goals of the Chesapeake Bay restoration is to reduce the impacts of excess nutrients on the Bay and its tributaries. In accordance with this goal, the Chesapeake Bay Program jurisdictions have agreed to reduce nitrogen, phosphorus and sediment pollution to the Bay. The Maryland Chesapeake Bay Tributary Water Quality Monitoring Program evaluates the physical/chemical component of water quality at sixty tributary stations. By measuring levels of nutrients and closely related habitat characteristics such as dissolved oxygen and water clarity, the monitoring program provides some of the most direct linkages to management actions that are reducing nutrient loads to the Bay.
Samples are collected monthly at each tributary station with one exception: samples are not routinely collected at station EE3.3 in January and February.
Note that prior to 2014, sixty-nine stations were included in the Tributary Monitoring Program. Due to funding constraints, the number of sites sampled was reduced by nine in 2014. Tributary water quality monitoring project sampling ceased in January 2014 at the following stations: BXK0031, CCM0069, MNK0146, XDJ9007, POK0087, XAK7810, TRQ0088, TRQ0146 and XCI4078.
Note that the year 2013 tributary project station count was sixty-nine. The number of project sampling stations was incorrectly listed as seventy, instead of sixty-nine, in metadata records describing project years preceding 2013.
Purpose:
The Maryland Department of Natural Resources Chesapeake Bay Water Quality Monitoring Program is part of a cooperative effort between the Federal government and State and local governments in the Chesapeake Bay watershed to assess the status and trends of nutrient and sediment concentrations in Maryland's Chesapeake Bay mainstem and its tidal tributaries.
The information is integrated with data from other Bay water quality stations and living resources monitoring projects and used to understand linkages, temporal variation and long-term trends.
Water quality data are used to refine, calibrate and validate Chesapeake Bay ecological models. The models are used to develop and assess water quality criteria with the goal of removing the Chesapeake Bay and its tidal rivers from the list of impaired waters.

Attribute_Accuracy_Report:
QUALITY ASSURANCE/QUALITY CONTROL Maryland Department of Natural Resources followed specific procedures to ensure that the Tributary component of the Chesapeake Bay Water Quality Monitoring Program design was properly implemented and managed with sufficient accuracy, precision and detection limits. Accuracy (closeness to the true value) of collected data was controlled and assured by proper use, calibration and maintenance of both field and laboratory equipment for the measurement of physical and chemical parameters.
The procedures used to control and assure the accuracy of field measurements involved the calibration of field instruments, the verification of calibrations, and equipment maintenance. Most of the details of how data acquired with YSI sondes and Hydrolab sondes were quality assured and quality controlled are described in the process description elements in the Lineage portion of this metadata record.
Daily quality control checks which included the running of blanks and standards were used to control and assure laboratory accuracy.
Accuracy of Chesapeake Biological Laboratory, Nutrient Analytical Services Laboratory (CBL NASL) results was also assessed through DNR's participation in the Chesapeake Bay Coordinated Split Sample Program (CSSP) a split sampling program in which five laboratories involved in Chesapeake Bay monitoring analyze the coordinated split samples. CSSP was established in June 1989 to establish a measure of comparability between sampling and analytical operations for water quality monitoring throughout the Chesapeake Bay and its tributaries. DNR followed the protocols in the Chesapeake Bay Coordinated Split Sample Program Implementation Guidelines (EPA 1991) and its revisions. Split samples were collected quarterly. Results were analyzed by appropriate statistical methods to determine if results differed significantly among labs. If a difference occurred, discussions began regarding techniques and potential methods changes to resolve discrepancies.
ADDITIONAL COMMENTS
January 2015: At stations EE3.0, EE3.1 and EE2.2, surface and 1.0 m samples were obtained from water collected at the same depth and, due to the absence of a pycnocline, above pycnocline and below pycnocline samples were taken from one third and two thirds of station total depth, respectively. At stations EE1.1 and WT5.1 it was noted that, by the time the water quality sonde was returned to the surface, conductivity readings had changed.
February 2015: It was not possible to conduct post calibration checks on the dissolved oxygen probe used at stations LE1.2, LE1.3 and LE1.4 due to failure of the probe. Out of range pH probe post-calibration results compromised pH results measured at stations: ET6.1, ET5.1 ET10.1 and WIW0141. Stations EE3.1 and EE3.2 above pycnocline and below pycnocline water samples were taken from one third and two thirds of station total depth, respectively, due to the absence of a pycnocline. Very low water was noted in the station TF1.3 field log. Roughly fifty dead fish were reported in the icy waters when station ET3.1 was sampled. Surface and 1.0 m samples at station WT5.1 came from water collected at the same depth.
March 2015: There were no pyncoclines at stations EE2.1 and EE2.1. The dissolved oxygen readings at station LE2.2 were confirmed by readings on a second water quality sonde. Rain fell during sample collections at stations PIS0033 and MAT0078.
April 2015: Above pycnocline and below pycnocline samples at stations EE1.1, EE2.1, EE3.1, EE3.2 and ET5.2 were collected from one third and two thirds of station water column depth. Post-calibration checks of pH probes, used to measure water quality at stations ET3.1, ET4.1, ET6.1 and ET10.0, were lower than the standard range values. Scattered rain showers fell the night before station ET6.1 was sampled. Heavy rainfall was reported the preceding night and during the morning of the day water samples were collected at stations LE1.1, LE1.2, LE1.3 and LE1.4.
May 2015: Scattered rain and thunderstorms occurred the weekend before stations PIS0033 and MAT0078 were sampled. Similarly, scattered thunderstorms were reported the night preceding sample collection at stations: LE1.1, LE1.2, LE1.3, LE1.4 and RET1.1. When samples were collected at stations TF1.3, TF1.4 and WXT0001, the river was characterized as muddy. Above pycnocline and below pycnocline samples at stations EE3.1, EE3.2, ET5.2 and were collected from one third and two thirds of station water column depth.
June 2015: An oil absorbing boom was deployed bank to bank fifty yards below station MAT0078 on the day samples were collected. No oil odor was detected. Stations’ EE1.1, EE3.1, ET4.2, LE2.2, RET2.4 and WT5.1 above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depths, respectively. A stormy night preceded sampling at station WT5.1. Heavy rain fell two days before samples were collected at stations WT1.1, WT2.1, WT3.1 and WT4.1.
July 2015: The total depth at the center of the bridge at station TF1.3 was described as greater than three meters. Rain showers fell during the morning samples were collected at stations ET1.1, ET2.1, ET2.2 and ET3.2. There were no pyncoclines at stations EE2.1, EE3.1, ET4.2 and ET5.2, therefore above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth. Thunderstorms occurred the nights preceding the days samples were collected at stations EE3.2, ET3.1 and ET4.1.
August 2015: The air temperature reading was questionable at stations TF1.5 and TF1.6. Significant meter scoping was noted at station ET10.1. There were no pycnoclines at stations: EE2.1, EE3.1, EE3.2, ET4.2, ET5.2, and RET2.4, therefore above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth. The occurrence of thunderstorms the previous night was noted at stations EE3.0, ET6.2, ET7.1 and WIW0141.
September 2015: The 6 meter depth sonde readings at station LE1.2 were double-checked. The Secchi disk depth was greater than the total depth at station TF1.3. There were no pyncoclines at stations EE2.1, EE3.1, EE3.2, ET4.2 and ET5.2, so above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth. Showers occurred the evening preceding sampling at stations TF1.3, TF1.4 and WXT0001.
October 2015: Rainfall the evening preceding sampling at stations TF1.3, TF1.4 and WXT0001 was noted. The Secchi disk depth was greater than the total depth at station TF1.3. The above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth at stations EE2.1, EE3.1 and ET5.2.
November 2015: Periodic plumes of oil rising to the water surface was noted at both station LE1.2 and station LE1.3. The water for the surface and 1 meter samples at station EE2.1 was collected at a single depth. Due to the absence of pycnoclines, above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth at stations: EE1.1, EE2.1, EE3.1, EE3.2, ET4.2 and ET5.2.
December 2015: The Secchi disk measurement was made in the sun at station LE1.1. The above pycnocline and below pycnocline samples were collected at one third and two thirds of the water column depth at stations: EE1.1, EE2.1, EE3.1, EE3.2, ET4.2 and ET5.2 because there were no pycnoclines.
Logical_Consistency_Report:
Beginning in 2014, due to funding, nine stations sampled in previous years, were dropped from the tributaries water quality monitoring program: BXK0031, CCM0069, MNK0146, POK0087, TRQ0088, TRQ0146, XAK7810, XCI4078 and XDJ9007.
January 2015: Ice conditions necessitated variations from normal sampling locations at three sites. Station ET5.2 samples were collected from the Talbot County side for the fishing pier. At station ET3.1, samples were collected at a different pier due to Ice along shore and usual pier. Station ET5.1 sampling was conducted from the boat ramp dock.
February 2015: Station TF1.3 samples were collected from the dock. Sampling at station ET5.2 was done on the Dorchester County side of the fishing pier.
March 2015: Station ET4.1 samples were collected from the upstream side of the bridge due to construction activity. Station TF1.3 samples were collected from the bridge.
April 2015: Station WIW0141 sampling was conducted from the Ferry.
May 2015: Station WIW0141 samples were collected from the Ferry and station TF1.3 samples were collected from the route 4 bridge.

Process_Description:
SONDE CALIBRATION and POST-CALIBRATION
The Yellow Springs Instrument (YSI) data sondes and HydroLab multi-parameter sondes were maintained and calibrated before and after each cruise in accordance with manufacturer's recommendations. During year 2014, YSI series 6820 and 6920 and Hydrolab series 3 (rarely), series 4A, and series 5 sondes were deployed. Field sheet dissolved oxygen method and equipment-set unit number values were used to track sondes used for station water quality measurements.
HYDROLAB PROFILE SAMPLING PROTOCOLS:
A profile of temperature, specific conductance, dissolved oxygen, and pH was obtained from the water column at 0.5 m, 1.0 m, 2.0 m and 3.0 m depth intervals below the surface. Thereafter readings were taken at 2.0 m intervals and at the bottom. Tributary bottom equals total depth minus one meter (not rounded). If the change in dissolved oxygen exceeded 1.0 mg/L or if the change in specific conductance equaled or exceeded 1,000 micromhos/cm over any 2.0 m interval, readings were taken at 1.0 m intervals between these two readings. For total depths less than or equal to 10.0 m, readings were taken at 1.0 m intervals.
GRAB SAMPLING DEPTH PROTOCOLS:
At stations where two depths were sampled, collections were taken at 0.5 m below the surface, and 1.0 m above the bottom. If the station total depth was equal to 1.5 m, the bottom sample was also collected at 0.5 m. Great caution was exercised when taking bottom samples; if the bottom was disturbed and bottom sediments appeared to have been included, the sample was dumped out and collected after the sediments had settled. Alternately, the sample was collected slightly higher in the water column and the new bottom sample depth was noted.
At stations where 4 depths were sampled and a pycnocline existed, collections were taken at 0.5 m below the surface, 1.5 m above the upper boundary of the pycnocline, 1.5 m below the lower boundary of the pycnocline, and 1 m above the bottom.
At stations where 4 depths were sampled and there was no discernable pycnocline, samples were taken at 0.5 m below the surface, at the closest profile depth one third the distance from the surface to the bottom, at the closest profile depth two thirds the distance from the surface to the bottom, and 1 m above the bottom.
Note that six Patuxent River stations, at which samples are also collected from four depths, use a different fixed-depth protocol for sampling mid-water depths. At station TF1.5 and RET1.1, samples are collected at 3 m and 6 m. Mid-water-column samples at stations LE1.1 and LE1.4 are collected at 3 m and 9 m. Samples are collected at 3 m and 12 m depths at stations LE1.2 and LE1.3.
SECCHI DEPTH:
Water transparency was determined, to the nearest 0.1 m using a 20-cm standard Secchi disc lowered into the water column with a calibrated rope. Observations were made on the shady side of the sampling location.

VERIFICATION AND DATA MANAGEMENT:
Each month DNR Tawes Office and Field Office personnel conducted data QA/QC procedures. All of the water quality calibration "grab" sample data were plotted. Outliers and anomalous values were thoroughly researched. Staff compared unusual values to historic values from the site and values from nearby sites. Weather events were considered, event logs were reviewed and CBL analytical laboratory staff and DNR field staff members were consulted regarding possible legitimate causes for outlying values. In cases where values were not considered to be legitimate, they were masked from the published dataset with the approval of the field staff and the Quality Assurance Officer.
