River Day

I’ve been working along the Central Platte River in Nebraska for close to 30 years now. Despite that, I’ve actually spent relatively little time in the river itself. As a grassland ecologist, most of my time has been focused on nearby prairies. The river sustains the groundwater beneath those prairies and it draws the sandhill cranes and geese that provide an annual soundtrack each spring. It’s much more than that, of course, but those are the attributes I’ve paid the most attention to.

The Central Platte River is a shallow braided river. At this time of year, it is a combination of exposed and barely submerged sandbars – all slowly moving downstream. Nikon 10.5mm fish eye lens. ISO 320, 1/200 sec, f/22.

During the last couple weeks, my college-age son John has been bugging me to take him out to splash around in the Platte. Last week, we found some time on a hot afternoon and enjoyed a couple hours in a quiet stretch of river – wading through channels, squishing through mud and sand, chasing toads, and more. It was so much fun that we couldn’t keep it to ourselves and we made another trip a couple days later, bringing Kim, Calvin and Atticus with us.

The boys had a great time playing on one of the sandbars – building sandbars, making mini river channels through the sand, and generally enjoying the day. Nikon 12-28mm lens at 12mm. ISO 320, 1/400 sec, f/10.

While the boys had noisy fun on a sandbar and Kim enjoyed some quiet time on another (far away) sandbar, I meandered around with my camera. As I did, I wondered why this kind of river exploration is such a rare part of my nature-based activities. I spent much of my time in a backwater channel (connected to the main channel only at the downstream end) where tiny fish and tadpoles zipped around much slower snails and other aquatic creatures. Killdeer and spotted sandpipers patrolled nearby, and red-winged blackbirds noisily let me know when I was too close to a nest on the higher, more vegetated islands.

This backwater wetland was full of life, including fish, tadpoles, snails, birds, frogs, and more. Nikon 12-28mm lens at 12mm. ISO 320, 1/800sec, f/13.
Little pools like this one were full of snails and tadpoles, along with other aquatic life. Raccoon tracks around the edge showed that this pool was well known by local predators. Nikon 10.5mm fish eye lens. ISO 320, 1/250 sec, f/18.

Killdeer were running all around the bare sand, making lots of noise and (I assume) keeping an eye on eggs or chicks nearby. Nikon 105mm macro lens. ISO 320, 1/400 sec, f/9.

Woodhouse’s toads were regulating their temperatures by sitting in shallow depressions in the wet sand. After I startled the first one out of its hole, I got better at spotting them before I got close enough to make them nervous. By slowly approaching them and staying low to the ground, I even managed to get a couple photos of them.

There were several Woodhouse’s toads in the backwater wetland, partially dug into the wet sand. They were firmly ensconced in their shallow depressions, coming out only if I got too close as I walked past. Nikon 10.5mm fish eye lens. ISO 320, 1/200 sec, f/18.
This clever toad took advantage of a deer track in the sand and just nestled into that. Nikon 105mm macro lens. ISO 320, 1/250 sec, f/13.
I didn’t see this toad until it hopped away from my feet and into some shallow water where it let me take a few photos of it. Nikon 105mm macro lens. ISO 320, 1/160 sec, f/13.
Water from as far away as the Rocky Mountains passes through the Central Platte on its way to the Gulf of Mexico. On the way, it provides drinking water for much of Nebraska, supplies irrigation water to many thousands of acres of crops, sustains groundwater levels beneath prairies and meadows, and – by the way – is important habitat for many fish, wildlife, and invertebrates.

It won’t come as a big revelation to most of you that rivers are a fun place to explore. It’s not exactly a revelation to me either, but it’s certainly an opportunity I’ve not taken advantage of very often. Hopefully, I’ll be a little less neglectful in the future. If I forget, I’m guessing the kids will remind me…

  1. Hi Chris
    I am from Australia but had a lovely quick trip through the sandhills in February before the SRM meeting in Denver. I was surprised to find such lovely open rolling country with such diversity so close to a main highway. Seeing the Platte river was also very special after reading about it in James Mitchener’s book Centennial many years ago.
    Your sagittaria spp. looks very similar to the one I sometimes encounter in gilgai ‘melonholes’ on heavy vertosols over here in our northern savannas. Unfortunately your toad reminds of our invasive cane toad that has caused so much damage to our native wildlife!
    Keep up the great blog and photographs.
    Cheers
    Peter O’Reagain
