After cancelling once because of the bitter cold, the LFWA stream team was out monitoring the Little Falls Branch last week, February 22. The weather cooperated - sunny and 41 degrees and the team was able to complete the task. They were excited to find a crane fly larva and a narrow winged damsel fly larva along with 6 other species despite the high salt levels seen this winter.
Our summer macroinvertebrate survey of the Little Falls Creek discovered only 8 species which gives the creek a poor rating for its biological health. The Summer macroinvertebrate count is part of our water quality monitoring program. We survey the creek 4 times a year to learn about its biological health.
Our stream monitoring team was thrilled to find a two-lined salamander at their spring monitoring session, April 21! This little salamander lays her eggs in the creek on the rocks and pebbles. While they are native to the area, we don’t see many in the creek because their habitat is frequently buried in the silt caused by eroding banks.
Thanks to everyone for an efficient and productive Fall Monitoring. With a plethora of volunteers - there were 9 of us - we recorded 106 macro's. Watching small minnow mayflies take flight might have been the highlight of the day or possibly finding one Narrow Winged Damsel Fly (thanks to Averill!).
Summer time is sowbug time in the Little Falls Branch! These freshwater crustaceans (Asellus aqaticus) live under the rocks and eat little bits of debris floating in the water. As is common in the summer, almost 20% of macroinvetebrates found in our summer stream monitoring session were sowbugs. Other stars of the July 9 survey were planaria and minnow mayflies.
Members of the LFWA Stream team were out in force April 8 for the spring monitoring of the Little Falls Branch. The exciting news is that a few minnow mayflies were spotted after a several seasons of absence. A large water main break in Westbard seems to have wiped out their population in Fall 2022, but we found four this spring. Hopefully, we’ll find even more in the summer. (Their numbers are usually in the in the dozens.)
Saturday was our quarterly benthic monitoring of the Little Falls Branch. The winter monitoring always yield low numbers and this year was no exception. Visit our Macroinvertebrate page to learn about the results.
Muddy water and a broken water main were the highlights of the Fall stream monitoring last Saturday, October 22. No sooner had our volunteers started to sample than the water started to rise and turn muddy. A woman passing by told us that there had been a water main break at a construction site upstream from our spot. With only three-quarters of the nettings complete, we abandon the water for safer ground.
