People are often surprised to learn that yes, there are fish living in Nine Mile Run and in fact… there are rather a LOT of them!

Led by NMRWA Monitoring Committee members Brady Porter and Michael Koryak, fish sampling is performed on an annual basis, typically in the fall. Since the stream restoration was completed in 2006, their data have shown marked improvement in the number and diversity of fish in the stream.

Immediately post-restoration, the entire stream was electro-fished and only 116 fish comprising seven different species were found. Today, it’s impossible to sample the entire length of the stream in one day due to the number of fish and time it would take to process them all!

For example, last Wednesday, NMRWA Monitoring Committee members and other volunteers sampled for fish in lower Nine Mile Run. Beginning at the mouth of the stream near Duck Hollow in the morning, and traveling upstream to finish just below the pedestrian bridge in the late afternoon, we caught nearly 2,300 fish comprising 17 different species! This is the second highest species count ever found in this section of the stream – 21 species were found in 2011.

Additionally, we found two new species that had never been collected from Nine Mile Run before: Gizzard shad and Silverjaw minnows. The addition of these two species brings the total species count of fish collected from this stretch of Nine Mile Run since 1999 to 30!

This week, barring inclement weather, we will finish our fish sampling for the year when we sample a section of the stream in the main part of Frick Park.

As always, thanks to Brady and Mike and all the volunteers who help make this important sampling effort happen!

Whoops! Sorry for going radio silent the past three months or so… Summer is always a busy time here at NMRWA, but that’s no excuse. Now that Fall is on the way, we’re ready to get back on a regular blogging schedule!

In the coming months, we’ll be posting about NMRWA events and workdays, information about native plants and animals, lists of other upcoming watershed community events, and more, so stay tuned.

Here are a couple snapshots to help recap our summer…

stilling well installation

In May, with Dr. Dan Bain from the University of Pittsburgh & students Tyler Paulina and Sarah Lavin, we installed a stilling well in upper Nine Mile Run.The stilling well holds a pressure transducer that records data related to the water height. That data, along with additional information being collected by a team of Urban EcoSteward volunteers, will be used to calculate streamflow. Understanding streamflow in Nine Mile Run will allow us to better understand various dynamics at play in the stream (e.g., nutrient transport, volume of stormwater introduced during storms).

In July, we hosted a group of summer interns from Phipps Conservatory that came to Nine Mile Run for a tour of the restoration area. Following the tour, they helped us remove invasive mugwort from along the Nine Mile Run trail.

In August, we joined forces with Allegheny CleanWays for a Tireless Friday clean up in Duck Hollow. With the help of roughly 30 volunteers, we filled a dumpster, removed two shopping carts, and 14 tires from lower Nine Mile Run and the surrounding banks of the Monongahela River.

Most recently, this past weekend we had fantastic weather for our 2014 Friends of the Watershed Cookout. We really enjoyed getting to spend time with all our supporters that were there – you can see more pictures from the day on our Facebook page!
