Expanded WikiWatershed® Toolkit Debuts

WikiWatershed is a Web toolkit presented by Stroud Water Research Center (the people who bring you Leaf Pack Network!) to help citizens, conservation practitioners, municipal decision-makers, researchers, educators, and students advance knowledge and stewardship of fresh water.

The WikiWatershed toolkit currently includes six tools.

  • Model My Watershed® is a watershed-modeling Web app that lets you analyze real geo-data, model storms, and compare conservation or development scenarios in any watershed in the continental U.S.
  • Micro Site Storm Runoff Model allows you to explore how land use and soil determine runoff for the Site Storm Model package of Model My Watershed.
  • EnviroDIY™ is an online community of do-it-yourself enthusiasts sharing open-source ideas for environmental science and monitoring.
  • Monitor My Watershed® is an interactive map-based Web app that lets you see streaming data from NOAA, USGS, and more. The Web app is currently limited to the Delaware River Basin.
  • Leaf Pack Network!
  • Trout Grow on Trees® is a hands-on environmental education program that shows how planting streamside forests can lead to cooler, cleaner streams and healthier wild trout populations.

Connect With LPN on Social Media!

We’d love to see photos of your group in action. Share photos on our Facebook page or use #leafpacknetwork and mention @leafpack on Twitter, @stroudcenter on Instagram.

If you’re not into the social media thing, email photos to webmaster@stroudcenter.org and we’d be happy to post them on the website.

Additional Resources

Macroinvertebrate ID

You can find helpful macroinvertebrate identification tips in back issues of the newsletter.

For example, our Macroinvertebrate Reviews focus on commonly misidentified macros, such as scuds and sowbugs, which are often mistaken for each other.

Amazing Mayfly Video

If you subscribe to the Stroud Center’s UpStream Newsletter, you might have seen our amazing mayfly video.

Unlike most mayfly species, Cloeon cognatum is ovoviviparous, which means that a mated female holds her eggs internally until embryonic development is complete.

Watch the video to see the eggs hatch less than a minute after being laid!


Would you like me to Skype in for a few minutes of class time? I’ll introduce the Leaf Pack Network, show how to make a leaf pack or simply say hello to your class and thank them for participating!

Feel free to email me!

That’s all the news for now. Don’t forget that you can find lots of great information in past issues of the LPN newsletter.

Enjoy your spring and we look forward to seeing your data soon on the Leaf Pack Network website!
