Linn Run Conservation Plan Work Continues with Macro Study

On Wednesday, June 16, FTTU volunteers gathered at the Grove Run Picnic area in Linn Run State Park to do a comprehensive aquatic macroinvertebrate collection and study of Linn Run and its tributaries. Andrea Kautz, Research Entomologist at the Powdermill Nature Reserve, and Josh Penatzer, Project Manager with the Loyalhanna Watershed Association, were the professionals who supervised the study. Previously, Andrea conducted a macro identification training session for volunteers via zoom, and both Andrea and Josh demonstrated the use of kick nets, explained the collection protocol, and oversaw the identification, sorting and scoring process on site. FTTU members with previous experience in macro collection led teams that carried out the kick net collection at 11 different sites within the watershed. Each site had at least 200 organisms captured. The samples were collected in buckets and brought back to the Grove Run Picnic Area where they were counted and sorted to the Genus level and then returned to the stream. All this work was carried out between 1:00 pm and 7:00 pm thanks to the great response we had from volunteers and Andrea and Josh’s guidance.

The numbers and types of macroinvertebrates inhabiting a stream are great indicators of stream health particularly the “high quality” Genus’s of mayflies, stoneflies and caddis flies.

The final report for the Linn Run Coldwater Conservation Plan will be produced in about one year.  The study is to determine the overall health of Linn Run and the fishery.  Next step, based on the information collected, is to determine if there are potential remediation projects we can undertake that might improve stream health and trout habitat.

Monthly Water Testing Results

“Neither rain nor snow nor dark of night…”, you know the saying. You may question their sanity, but the FTTU citizen scientists were out in the rain and snow and mist and fog to do our monthly water quality tests at the mouth of Rock Run. We visited two other Linn Run tributaries Grove Run and Quarry Run and took samples there as well. The flow in the watershed was healthy do to snow melt and rain which also stesses the alkalinity of the streams. Rock Run has the lowest alkalinity of the three, which is what led to out limestone treatment project there. Quarry Run, which is basically a large spring, has the best water quality of the three.

Air Temperature: 37° F
Linn Run Discharge: 19
Linn Run Gauge Height: 2.16

Rock Run
Water Temperature: 41.5° F
pH: 7.3
Alkalinity: 3.1

Grove Run
Water Temperature: 39.5°
pH: 7.2
Alkalinity: 6.2

Quarry Run
Water Temperature: 40.5°
pH: 7.2
Alkalinity: 16.6

Rock Run Water Testing for February 2021

Rock Run January 30, 2021
Denny Hess takes a temperature reading near the mouth of Rock Run.

You may question their sanity, but the FTTU testing crew was out with temperatures in the teens at Rock Run taking water samples this past Saturday.
It was a “crisp” but beautiful winter day at Linn Run State Park, Rock Run was flowing moderate and as always, clear.

Air Temp: 19 degrees F
Water Temp: 29.5 degrees F
Linn Run Gauge: 1.91 ft.
Linn Run Discharge: 21.8 ft³/sec.
pH: 7.6
Alkalinity: 3.2

We also collected some snow from around the area, allowed it to melt, and took readings of those samples as well.
pH: 7.3
Alkalinity: 4.5

Rock Run, January 2, 2021

 

A new year of water quality testing begins on Rock Run. The flow is high with rain and snow runoff, so the stream’s alkalinity content is put to the test.

Air Temperature: 39 degrees F
Water Temperature: 40.5 degrees F
Linn Run discharge: 22.0
Linn Run gauge: 2.88
pH: 6.8
Alkalinity: 2.6
