PURPOSE:

This experiment was designed to assess the residence times of water in the channel and hyporheic zones of the lower reach of Watershed 3 and two adjacent reaches of 4th-order Lookout Creek.

METHODS:

Experimental Design - HF011:

Description:

Tracer injection and monitoring points were surveyed (Anderson, 2002), and added to the digitized maps (LO410 and 411). Source area for each reach was calculated from a 10-meter digital elevation model (DEM). Sinuosity was calculated as the thalweg length divided by the straight-line distance along the valley axis for each reach. Stream discharge in reaches 410 and 410/411 was measured by wading, using a Marsh-McBirney model 200 flow meter (Marsh-McBirney, Inc., Fredrick, MD, USA). Stream discharge in WS03 was measured at the gauge house at the bottom of the reach. All samples collected with ISCO auto samplers (ISCO, Inc., Lincoln, NE) were analyzed with the same Turner Designs fluorometers (Turner Designs, Inc, Sunnyvale, CA) in a lab within 24 hr of retrieval. Three slug tracer experiments were performed on separate reaches in the HJ Andrews Experimenatl Forest.

Field Methods - HF011:

Description:

Watershed 3 (Tracer Test 1), April 21, 2001

• Eleven grams of Rhodamine WT (RWT, Fomulabs, Piqua, OH) was injected into the WS03 stream reach.
• Stream flow was measured at a stream gauge at the bottom of the reach for the first 15.7 hrs of the experiment
• RWT fluorescence data was collected at a downstream sample point using a Turner Designs model 10AU field fluorometer.
• Data was collected on a five-second interval for the first 28 hr. For the remainder of the experiment, stream water samples were collected with programmable field auto samplers for an additional 7 days.

Lookout Creek, Reach 411 (Tracer Test 2), July 10, 2001

• 10.4 g of RWT was injected at the head of the LO411 stream reach.
• Stream flow was measured by wading, using a Marsh-McBirney model 200 flow meter at the end of the reach prior to the injection.
• RWT fluorescence data was collected at a downstream sample point using a Turner Designs model 10AU field fluorometer.
• Data was collected on a 10-second interval for the first 6.3 hrs. For the remainder of the experiment, stream water samples were collected with programmable field auto samplers for an additional 4 days.

Lookout Creek, Reach 410/411 (Tracer Test 3), July 18, 2001

• Seventy-five grams of RWT (Bright Dyes, Miamisburg, OH) was injected at the head of the LO410-411 stream reaches.
• Stream flow was measured by wading, using a Marsh-McBirney model 200 flow meter at the end of the LO411 reach at 14 hrs prior to the tracer experiment, and 10 hrs after the start of the experiment, respectively.
• RWT fluorescence data was collected at a downstream sample point using a Turner Designs model 10AU field fluorometer and a Turner Designs Model 10-005 R field fluorometer for LO411 and 410 respectively. Both were set up with a flow-through cell.
• Data was collected on a 10-second interval for the first seven hrs. For the remainder of the experiment, stream water samples were collected with programmable field auto samplers for an additional 4 days.

SUPPLEMENTAL INFORMATION:

Entities labeled “(E)” refer to early time data, collected in real time with a field fluorometer. Entities labeled “(L)” refer to late time data, collected as water samples using an ISCO auto sampler and analyzed no more than 24 hours after retrieval in the laboratory with the same field fluorometer used for the early time data. Tracer 3 has early and late time information on the same sheet to conserve the number of sheets in the database. Tracer 3 also has two sets of concentration data, one from the bottom of the 410 reach, labeled Tracer 3 (410) and data from the bottom of reach 411, labeled Tracer 3 (411).
