Water Properties

In our winter wonderland, water is all around. It piles upon the landscape in great white drifts. It is a substance life is completely dependent upon and as ordinary as it seems, this tasteless, odorless substance is actually quite amazing. Up to 60% of our body mass is due to water, and life as we know it would not exist if not for water’s unique physical properties.

Properties of Water

When most known liquids get colder they contract – shrinking around 10 percent in total volume. Water contracts too, but only until it reaches its freezing point, at which time it reverses course and begins to expand. This molecular marvel does wonderful things for life on earth. As water freezes and expands, the resulting ice becomes lighter than its liquid form, causing it to float. If ice contracted as other liquids do, it would sink, and lakes would freeze from the bottom up – and freeze quickly, meaning big changes for aquatic life. Water in all forms happens to be a very good insulator, meaning that it doesn’t change temperature very quickly. Ice floating on top of a pond insulates the water underneath, keeping it warmer, and therefore liquid, longer than it normally would. Obviously, this is beneficial for local creatures like fish and beavers not to mention the penguins, whales and seals that thrive in the colder parts of our planet.

Another critical property of water is its stickiness. Individual molecules are generally more attracted to each other than to other substances such as air or soil. This ‘stickiness’, or cohesion, creates surface tension, which allow puddles, rivers, and raindrops to form, and also enables water striders to glide on the water’s surface and rocks to skip across a lake. Water tension is also responsible for a tree’s ability to siphon water from the soil and transport it to the very topmost leaf. However, water’s bonds aren’t so strong as to be unable to break when a fish swims through or when you cannonball into the deep end. You can observe surface tension at home by dripping water onto the head of a coin, and watching it ball up into a surprisingly large mound.

Water is also one of the only known substances that naturally occurs in three phases – solid, liquid, and gas. This is important to many facets of life including the proper functioning of the weather system as we know it. Thankfully, there is a lot of water here on earth – about 320 million cubic miles of it. However, only four tenths of a percent of that comes in the form of freshwater lakes & rivers. Most of the rest is locked up in glaciers and oceans. It’s also important to realize that this is all of the water that Earth has ever had, and all the water we’re ever going to get, which can lead to some interesting thoughts about where that water you are about to drink has previously been. Perhaps it was once part of Lake Bonneville, in the snow that fell on the back of a wooly mammoth, or in a puddle slurped up by a brachiosaurus. If only water could talk…

National Park or National Monument?

Established in 1916 the National Park Service manages all properties included in the National Park System. This system includes over 400 areas that encompass more than 84 million acres of land. These areas can go by one of 31 different titles. Within this system, Utah boasts 1 national historic site, 2 national recreation areas, 7 national monuments, and 5 national parks. While the reason for some of these titles is self-explanatory, the reason for others is less clear. National Park or National Monument?

For example, what makes one area a “national park” and another a “national monument?” Most people – including myself – would probably guess that the difference is in size. And while this is sometimes true, the primary difference is the reason for which each is established, because these two designations grew from historically separate concepts. The notion of the national park, which was simply the idea of large-scale natural preservation for public enjoyment, grew in popularity throughout the 1800s. As a result you can typically think of a national park as a spectacular scenic feature or natural phenomena preserved for inspirational, educational, and recreational value.

On the other hand, the idea of the national monument arose as a result of the need and desire to also protect prehistoric cliff dwellings, pueblo remains, and other historic ruins found by explorers of the American West and Southwest. Efforts to protect these sites resulted in the passing of the Antiquities Act of 1906. Therefore a national monument is usually designated to preserve objects of prehistoric, historic, cultural, and/or scientific interest. However, the Antiquities Act has been used more widely to preserve natural features as well, meaning the content of national monuments can be quite varied from wilderness areas to military sites to buildings and ruins.

There are also a couple of legal differences between these two designations. National parks are established through acts of Congress, whereas national monuments are established by Presidential proclamation. Administratively, the National Park Service manages all national parks. While national monuments, depending on their location and content, can fall under not only under the jurisdiction of the National Park Service, but also that of the U.S. Forest Service, the U.S. Fish and Wildlife Service, the National Oceanic and Atmospheric Administration, the Department of Defense, or the Bureau of Land Management.

So, it’s not just size that makes the difference, its intent, content, process of establishment, and administration. The next time you visit one of Utah’s national parks or monuments, will you be able to tell the difference?

-Wetlands-What’s in a name?

Hi, this is Mark Larese-Casanova from the Utah Master Naturalist Program at Utah State University Extension.-Wetlands-What’s in a name?

A wetland really is more than just ‘land that is wet’. There are certain key ingredients that need to go into a wetland for it to truly be a wetland. Of course, water needs to be present for at least part of the growing season. It can simply be in the form of temporarily saturated soils or even standing water a few feet deep.

As soil becomes saturated with water, oxygen levels are greatly reduced. Quite often, bacteria in saturated soils will create hydrogen sulfide, giving wetland soils that stinky odor of rotten eggs. As plants grow in a wetland over several years, their decaying matter helps to create a thick, dark layer of organic soil.

The presence of water in a wetland encourages the growth of hydrophytes, or ‘water-loving’ plants, that are specially adapted to living in wet environments. Many wetland plants have open spaces within the leaves and stems- often referred to as aerenchyma. This allows oxygen to diffuse down to the roots, sometimes creating an oxygen-rich environment in the soil around a plant. Also, many wetland plants reproduce both by floating or wind-dispersed seeds and by rhizomes, which are underground roots that can travel great distances. Some plants that grow in salty wetlands around Great Salt Lake are able to control the salt in their tissues by depositing it on the outside of the leaf or containing it in chambers within their cells.

Like plants, specially adapted animals also call wetlands their home. Mammals and birds have oily fur or feathers that allow them to swim in cold water without losing much body heat. They also often have webbed feet to aid in swimming. Other animals, such as fish, amphibians, and insects, have gills to breathe in water.

Despite being the second driest state in the country, Utah has a high diversity of wetlands. Vast marshes surround the Great Salt Lake, providing habitat to enormous populations of migratory birds. Less obvious wet meadows provide unique habitat to butterflies and other insects. Salty playas which are shallow basins with no outlet, are found throughout the West Desert, creating unique ecosystems of highly adapted plants. Riparian wetlands can grow along the edges of rivers, providing a unique transition between the swift water and upland habitats. Southern Utah is home to some peculiar wetlands such as potholes and hanging gardens, both associated with sandstone bedrock. A hanging garden clings to the side of a moist cliff, creating a microhabitat for rare plants, such as orchids and monkeyflower. Potholes can simply be eroded basins in the sandstone where water collects in spring. A pothole is an oasis that provides water for desert wildlife and a home for fairy shrimp and spadefoot toads.

Spring is the perfect time of year to visit a wetland. The constant chorus of birds, insects, and amphibians are a testament to the importance of wetlands, teeming with life in the middle of a desert.

Hi, this is Mark Larese-Casanova from the Utah Master Naturalist Program at Utah State University Extension.

The Colorado River Compact, written into law almost a century ago, helped ensure our survival in Utah today. We all know that Utah is a dry state. In fact, Utah is the second driest state in the country, with only Nevada being drier. Our average annual precipitation varies widely, from as low as a few inches a year near St. George, to as high as 60 inches in the mountains. Since most of our water comes from mountain snow, we rely on rivers and streams to deliver it to us.

The Colorado and Green Rivers, the largest in Utah, carry water from the Rocky, Wasatch, and Uinta Mountain ranges throughout Utah and the Intermountain West. The Colorado River Basin, the area of land from which the Colorado River and its tributaries drain water, covers the eastern half of Utah, along with the western half of Colorado, almost all of Arizona, and small parts of Wyoming, New Mexico, Nevada, and California. Each of these states has a dry climate, and water from the Colorado has always been in high demand.

In the heavily populated eastern United States, the right to use water often adheres to Riparian Doctrine in which water is shared by all those who live along the body of water. However, the western US was settled at different times, and populations are more sparse. So, water rights generally follow the doctrine of Prior Appropriation. That is, the water is set aside for whoever is able to use it first. The only problem is that California was developed earlier than the other states in the basin, and therefore, as the US Supreme Court ruled in 1922, was legally entitled to more than their fair share of the water! In this case, western water law simply didn’t work. So, all 7 states in the Colorado River Basin sat down together with the US Government and negotiated the Colorado River Compact to ensure that Utah and the other Upper Basin states were entitled to as much water each year as California and the other Lower Basin states that were growing at a faster rate.

So there you have it- one key piece of legislation helping to save civilization in Utah. Except, well, the amounts of water each state is entitled to was based on an abnormally high year of water flow… and, so, there often isn’t enough water to go around… and Mexico doesn’t seem to get much water at all. OK, so the Colorado River Compact isn’t perfect, but it’s important. To ensure that we all truly have enough water, it will take compromise, conservation, and a whole lot of common sense.
