Rock Run Water Tests For February 2022

Mouth of Rock Run 2/6/22
The Mouth of Rock Run 2/6/22

Neither rain nor snow nor frigid winter temperatures will keep the FTTU citizen scientists from their appointed rounds! A beautiful winter morning greeted the testers at Linn Run State Park on February 6th. Water levels were up with recent rain and snow melt and the air temperature was a chilly 17°.

Air Temperature – 17° Fahrenheit
Water Temperature – 34° Fahrenheit
Linn Run Gauge – 2.24 ft.
Linn Run Flow – 33.3 ft³/sec
pH – 7.7
Alkalinity – 2.8

The idea here is to record monthly pH and alkalinity readings at the mouth of Rock Run to track the progress of the chapter’s acid mitigation project on this important Linn Run tributary. The limestone sand deposits are placed in the headwaters to treat the stream for acidity. If readings at the mouth are good, then it can be presumed that alkalinity and pH in the entire stream must be healthy. A goal would be to have alkalinity readings of 10 at the mouth. We haven’t reached that goal consistently yet. Higher flows typically bring alkalinity numbers down as we see in his month’s readings, but overall, alkalinity of the stream has improved since the project began.

Year End Rock Run Water Tests

Mouth of Rock Run
The Mouth of Rock Run 11-27-21

Icy temperatures and the first dusting of snow greeted the testers as the final water sampling at the mouth of Rock Run for 2021 was done on Saturday, November 27.

Air Temperature: 25° F
Water Temperature: 34.5°F
Linn Run Discharge: 7.95 ft³/sec
Linn Run Gauge: 1.76 ft.
pH: 7.7
Alkalinity: 7.8

The final averages for the year are 7.43 pH and 7.03 alkalinity. These are the best averages we’ve recorded since we began taking monthly readings in 2017.
2017-2018: pH-6.47, Alkalinity-5.9
2018-2019: pH-6.5, Alkalinity-6.1
2019: pH-6.5, Alkalinity-6.2
2020: pH-6.88, Alkalinity-5.92
2021: pH-7.43, Alkalinity-7.03

Plans are to add limestone to the headwaters in 2022.

Linn Run Cold Water Conservation Plan Update

Kick Net
Elizabeth Bruner inspects rock for aquatic organisms while Luke Sanner collects bugs in his net as they are flushed downstream.

Forbes Trail members and local volunteers wrapped up three days of water quality sampling and macroinvertebrate (trout bugs) studies on Linn Run and its tributaries in mid-November. They enjoyed beautiful weather for two of the days. But, the last day of macro, they had to deal with rain, falling temperatures and working under a dark pavilion to sort and identify the bugs. All in all, they collected a large quantity and wide assortment of bugs and the water quality in the stream is looking good.

Andrea Kautz from Powdermill Nature Reserve and Josh Penatzer from Loyalhanna Watershed Association were the bug experts assisting volunteers with sorting and making correct identifications. Strict protocols have to be followed for collecting the bugs from the stream, including the length of stream sampled, how long to kick the stream rocks and debris, and specific mesh nets to be used. The sorting and identification is a very tedious and eye-straining activity. Many of the bugs must be picked from leaf packs with tweezers.

Water quality samples were first analyzed stream-side by TU members for a number of parameters including pH, alkalinity and dissolved oxygen. Duplicate samples are being analyzed at St. Vincent College for additional parameters using a Microwave Plasma Atomic Emission Spectrophotometer. Analyses there include nitrates, phosphates and metals. Collectively the results will tell the overall health of the stream and its ability to support wild trout.

We thank all of the TU members and volunteers who gave of their time and talents to complete this portion of the study. We’ve had several volunteers from the PA Master Naturalist program offer their skills and expertise over the past year. We offer a special thank you to Elizabeth Bruner who is a 4-H and TU member and homeschooled senior from Blairsville, and Luke Sanner, 4-H member and sophomore at Hempfield High School for their participation. We are pleased to see the younger generation taking such an interest in coldwater conservation projects.

Rock Run Water Tests November 2021

Mouth of Rock Run
The Mouth of Rock Run 10.30.21

Here’s the results of water tests for November 2021 (taken October 30).

Air Temperature: 50° F
Water Temperature: 51º F
Linn Run Discharge: 16.0 ft³/sec
pH: 7.6
Alkalinity: 8.4

Good sign that alkalinity held up pretty well with recent rains and increased flow.

A kick-net survey was also done on the lower section of Rock Run. The survey scored a 28.4 which is in the fair range for a water quality score.

Woolly Adelgid Educational Video

Adelgid Eggs
Woolly Adelgid eggs on hemlock branches.

The Woolly Adelgid is an invasive insect pest that threatens and can kill our state tree, the hemlock. Hemlock trees go hand-in-hand with brook trout streams in Pennsylvania.
FTTU’s Ron Miller has put together an excellent video that explains it all and what’s being done to save our hemlocks locally at Linn Run State Park.
