Reddish brown pond water

Asked July 31, 2017, 6:56 PM EDT

We live just north of palmyra on an acreage. We dug a pond about 10 years ago while leveling out an area for an out building. It is only fed by runoff from our land. The depth varies throughout the year from probably 6-9 feet at its deepest to 2-3 feet when the weather is dry. For the first time ever the water has turned a distinct brownish-red color (iron color?) since a recent rain. I think it might be some algae of some kind. It is less in the morning, but the color increases as the day warms up. There are no fish in it, just many frogs and dragon flies. There seem to possibly be fewer frogs since this started about a week ago and I've only seen larger frogs. Wondering what this is and what, if anything should/can we do about it? Thanks for any help!

Hi there,

I have asked a colleague to take a look at these pictures. I have a few additional questions for you so that I can help identify what's happening. Could you send an email directly to me at and cc my colleague at the NDEQ?
