Follow the Water - 3 - Park City

 

 

Water use in the Park City area was historically focused on surface water, which was used for agriculture and mining processing. Ground water was a nuisance to mining and was pumped or drained to the surface for disposal.  Now it drains through the mine tunnels and is fed by gravity to our new 120-million-dollar water treatment plant that removes heavy metals such as Arsenic, Mercury, Cadmium and Lead Zeppelin.  Streams have dried as this water has been used in the city and sold to purveyors in the Snyderville Basin to help pay for the new treatment plant.  Everything is a tradeoff.  You don’t get something for nothing.

 

With the modern change from mining and agricultural water use to municipal uses, the demand has shifted from surface water treatment to the capture of cool, clean groundwater.   Municipal wells in the Park City area therefore withdraw water from consolidated rocks, such as the fractured and faulted limestone and sandstone.  These rock formations are locally broken into separate block formations that can inhibit or isolate water flow and withdrawal, which can make finding reliable water difficult.  Water that recharges in the bedrock outcrops in the mountains, typically takes 15 to 40 years to move through the system, although much older water can still be found stored in the underlying bedrock and aquifers.  Because of the low capacity for bedrock ground water storage, the hydrological system is very dependent on the amount of annual precipitation and is therefore sensitive to prolonged drought and climate change.  Less than normal precipitation or overuse can result in substantial groundwater level decline, both in the bedrock (affecting municipal wells), and in the basin fill (affecting stream flow). 

 

In addition, the under-drain effect of the system of mine tunnels below our town also influences surface waters and subsequent ground water flows, inhibiting recharge and draining some water out of the basin toward Jordenelle, East Canyon and Echo, and even Snowbird and Brighton.  Mining related sinkholes, historically opened along Silver Creek and elsewhere, can capture the entire stream and direct it underground towards our aquifers or towards other drainages.   Because of our increased use of surface waters and springs, the local stream flows have diminished and historical recharge to the aquifer have suffered.  Unfortunately, in-stream flows are hard to protect in Utah where only the DNR Divisions of Wildlife and Parks can hold an in-stream right.  Protecting stream flows and establishing a base or minimum flow for water quality and wildlife or for riparian habitat and aesthetics, is difficult in this climate of low supply, high demand, and expensive water rights.  This protection may require cooperation of all the stakeholders and leadership to enable new legislation of in-stream flows. 

 

The public owns the water of the State, and the State Engineer distributes it to all for ‘beneficial use’ and economic development, till it is all gone.  The State Engineer must consider other issues when approving a water right, such as availability, interference, speculation, economic feasibility, recreation, natural stream environment and ‘public welfare.’  Fish and flowing water unfortunately are not considered a ‘beneficial use’ by the State Engineer and public welfare is hard to define.    But if the people lead, the leaders will follow.  It is we, who dictate what the ‘public welfare’ is, that must be protected by The State Engineer and our legislators.  We must send policy and law makers a strong message that we value clean, flowing water and the riparian environment that contribute to the quality of life that we all cherish.  Clearly, drying up the Great Salt Lake or The Colorado river is not good for public welfare.

 

The changing picture of the future of the Park City water resources is full of challenges.  This is a system, surely affected by man and climate, which is a system out of balance.  Our water supply is now being taxed to its limits both in water quantity and water quality.  Park City’s historical punitive-conservation rates have been repealed recently, at the request of some fat cats, allowing big users to waste water at the expense of small users who conserve.  Water flows downhill, but it also flows towards money.  How much will we pay for good water when we are thirsty?  What are the full costs of our consumption?  Water is an inelastic commodity and when we need it, price is not an issue.   Our affluence enables us to access the water within our basin and reach beyond its borders for augmentation, but it also inhibits our desire and ability to live within our natural basin means, as John Wesley Powell encouraged us to do more than one hundred and fifty years ago. 

 

We need to consider the needs and rights of our neighbors, the cost of our desires to the streams and wildlife as well as the limits of the natural systems that sustain us.  If we work at it, together we can live in harmony with our environment and with each other.  Picture the Native American Utes at their summer camp in our basin only 200 years ago, with grasses up to the belly of a Bison, a hydrologic system in balance.  Let that be our guide and goal.  Sustainability will require good science and engineering, legislation and regulation, conservation, and cooperation, which will respect the limits of nature and our environment and reveal the priorities and character of this great community.   

 

Keep Park City Kind.  Keep Park City Cool.
