Summer Tech Will Treasure Experience for a Lifetime

Summer Tech Will Treasure Experience for a Lifetime

The experience of working at Lake McConaughy is something I’ll hold onto for the rest of my life.

I spent a second summer at Lake McConaughy working as a biological technician for The Central Nebraska Public Power and Irrigation District. The gorgeous landscape that surrounds the huge lake is remarkable and the white sandy beaches make the lake unlike any other I’ve seen. The sandy shorelines make an excellent destination for campers and outdoor enthusiasts from all over, but people are not the only ones utilizing the beaches.

Piping plovers and least terns are small shorebirds that also call Lake McConaughy home during the summer months. These magnificent birds are ground nesters and the fine sandy beaches of Lake Mac make the perfect habitat in which to hide their eggs. But because the birds share their nesting sites with people who are enjoying the lake, their nests are in danger of accidental destruction from getting run over, stepped on, or destroyed by unleashed pets. This is where my job becomes important.

During the early months of the summer – late May and June — a typical day for me would be to survey the beach, searching for plover and tern nests and eggs, which is more difficult than one might imagine. The eggs are slightly smaller than a quarter and blend into the sand extremely well, which is the reason they nest in open, sandy places.

Once a nest is located, certain actions must take place to ensure that it has the greatest possible chance of producing eggs and chicks. In areas where human traffic is heavy, an enclosure is constructed around the nest, consisting of orange flagging and signs to make it as visible as possible to beach-goers. The enclosures are large enough that the bird will feel comfortable sitting on the nest as people drive or walk by. In certain areas around the lake where nests are more frequently established, a much larger enclosure is built. These enclosures could have more than ten nests inside them, and make it possible for the birds and chicks to go all summer without human interaction. As the summer progresses, the eggs begin to hatch and then comes the difficult task of keeping track of all the chicks on the beach until they are old enough to take flight. This can be difficult as the chicks can roam a great distance in either direction in a single day. However, this summer was much different than last.

Early in the summer, we had many much needed rain showers, causing flows in the North Platte River to rise dramatically. This meant a high volume of water flowing into the lake, which raised its elevation by more than a foot a week. The beaches rapidly disappeared as the birds were trying to find a suitable spot to make a nest. Just as the birds would find a site, the location would become inundated by the rising lake. As days passed, more and more birds left the lake in search of different locations to nest. By the end of the July, which is the natural deadline for these birds to make a new nest, we had no successful nests as the lake rose to 97 percent of its capacity. All suitable habitats were covered by water and the birds were forced to leave without having a successful nesting year at the lake. However, these birds tend to be resilient and will surely be back next year to give it another go!

This summer at the lake was one of the most interesting experiences I have had. Watching how the birds reacted to the water rising and seeing them battle each other for territory on what little beach remained was a sight unlike any other. This summer also showed me just how much natural changes can affect the entire ecosystem of the lake. Not only were the birds forced to leave without successfully nesting, but people had to find other areas to park their campers or pitch their tents , which was quite a sight to see. The fishing at Lake Mac quickly became more challenging as the summer went on. As the lake expanded, so did the areas in which fish could forage or take cover. Watching how fisherman reacted and tried new tactics was also interesting to me, as I am an avid fisherman.

All in all, one of the most important lessons I learned this summer is that things don’t always go as planned, but you have to be ready for whatever happens and learn to adapt to the situation that you encounter. I am thankful I am able to come away from this experience with such an important life lesson!

No, they weren’t taken along a wild and scenic river, or at some national park. These photos were taken along Central’s Supply Canal, which runs from just east of North Platte to east of Lexington. Many sections of the canal wind through high banks, and narrow canyons.

The public is permitted to use the entire length of the canal for recreational purposes, excluding areas around Central’s three hydroelectric plants and NPPD’s Canaday Steam Plant. Portages around check structures are relatively easy, but getting around the hydroplants requires a lengthier overland trek. Launching a canoe or kayak may be difficult in some spots because of the shoreline protection materials (in most cases, broken concrete riprap). Many sections of the canal are paralleled by maintenance roads or state and county roads. The flow in the canal is relatively constant year-round, the water is 15 to 20 feet deep in most places, and the current is not rapid (no whitewater stretches), although caution should be exercised when approaching check gates.

The 75-mile-long Supply Canal and its many canyon lakes are used for hunting, hiking, canoeing and kayaking, camping and fishing. Only wakeless boating is allowed on the canal to prevent bank erosion.

Also, when planning a canoe or kayak trip, it’s a good idea to remember these helpful hints from the Nebraska Game and Parks Commission:

  • Wear your life jacket.
  • Take a spare paddle.
  • Don’t canoe alone.
  • Have tether ropes on both ends of the canoe.
  • Take insect repellant.
  • Take ample water.
  • Take sunscreen, sunglasses, and wide-brim hat. The sun’s reflection off the water can be intense. If it is hot, start early or later in the day and make the trip shorter.
  • Put extra clothing, gear, and food in water-proof bags.
  • Take rain gear, but not ponchos.
  • Take first aid kit. Learn what poison ivy and poison oak look like, as well as black widow and brown recluse spiders.
  • Avoid contact with livestock and wild animals.
  • Protect your feet with tightfitting wading shoes.
  • Camp only in designated areas. Obtain permission prior to camping on, or entering the water from, private land.
  • Read maps and plan ahead. Be off the water before dark.
  • TRASH: If you create it, e.g., cans, bottles, food wrappers, etc., pack it out. Don’t discard it in the water.
  • Build fires only in fire rings; drown flames and coals after use. If no fire ring exists, use only camp stoves.
  • Use caution when loading and unloading near highway or county bridges.
  • And remember, Nebraska’s weather can be unpredictable and prone to extremes of temperature, humidity, wind and rate of change. Summer storms rapidly form, are fast-moving and can have rain, hail, high winds, lightning, and tornados combined.  Pay attention to signs of bad weather, get off the water and take cover as quickly as possible if a storm is approaching.
