Northern Tallgrass Prairie NWR Pavia Unit early Spring 2021...

The pond has a lot of water in it and things are slow but surely greening up.

Note the fence crossing under water. This previously burned area is very important to a lot of different species birds, etc. not just ones that will nest there but many migrating through as a temporary stop over area. The frogs etc. seem to like the pond and cattails.

... a couple marbled godwits on shore and some of those greater yellowlegs at waters edge.

... intermittent stream or outflow. It is not a regular stream channel like most streams or creeks it just kind of finds its way though the grasses and terrain as it meanders out. It has become less noticeable in the past weeks compared to when it actually had a flow or current noticeable.

Burned out 3-18-21...

They had real good weather yesterday barely a breeze. It needed a cleaning out. Glad they got it burned out this early in the season. Should grow back nicer than before.

  Stream Flowing out of the pond at Northern Tallgrass Prairie NWR Pavia Unit Spring 2021.

This was a week or so ago. As of today April 27, 2021 the flow is not noticeable and the water seems to more so sit. Probably moving but so slow you don’t see it. Guessing some of the plants growing now are also helping to soak it up.

Some time back we had some rain up here and some snow and that brought up that pond and got that outlet draining. A few weeks or so after the prescribed burning there was no water draining since there hadn’t been much snow all winter. But we did get some spring rain and snow after that...

There are a lot of Snipes at the Pavia Unit I noticed too. Hard to notice them they blend right in. It can be hard to sometimes even see those marbled godwits but with the greening up they are starting to be more noticeable.
