The prosperous John Lapsley (Laps) Ish family are an example of very successful settlers and entrepreneurs in early Grand County. The Ish family, with eleven children, came by covered wagon to Colorado from Missouri 1863 and settled on a farm outside of Denver.

18-year-old Laps Ish came to Grand County in 1881 to attempt his luck at the short lived mining boom outside of Teller, north of Grand Lake.  He tried his luck at mining for 4 years and also carried the mail between Teller and Grand Lake, on skis or snowshoes in the winter and by foot in the summer. 

Laps Ish married Alice Shearer and homesteaded near Rand (in present day Jackson County). They had two sons, Lesley John Ish and Guy Lapsley Ish. Laps and Alice built the Rand Hotel and operated it until 1910.  The family then moved to Granby and built the Middle Park Auto Company garage and ran a stage line to Grand Lake. They built the Rapids Lodge by operating a sawmill on the Tonahutu River in Grand Lake and opened for business in 1915  They also built the Pine Cone Inn in Grand Lake and Leslie managed it for many years. Laps Ish died in 1943.

Grand County is home to the headwaters of the famed Colorado River — the river that brings water to five other arid Western states. Water is the lifeblood of semi-arid Colorado and Grand County is one of the most water-rich areas of Colorado, and yet faces a shortage due to historical water agreements, written long before population pressures and the environmental awareness of the current age.

On average, the water diversion projects in the county move a whopping 305,000 acre-feet per year from the Fraser, Colorado and Williams Fork rivers — all headwaters of the Colorado's main stem. 60 percent of the water in Grand County is diverted elsewhere and there are plans underway, mostly from Front Range communities, to divert as much as 80 percent of the county's headwaters by the year 2010.

Two of the main water utilities, Denver Water and the Northern Colorado Water Conservancy District face a quandary: how to take the water from Grand County without further damaging the delicate environment and the region's economy, which is fueled by tourists who expect to play in the very water the Front Range wants to take.

Many noted fur trappers and traders are reported to have been familiar with the headwaters of the Grand (Colorado) River as early as the 1820s. Among them were Thomas Fitzpatrick, Jim Beckwurth, Christopher “Kit “Carson, Henry Fraeb and Peter Sarpy. Louis Vasquez built a trading fort on the South Platte River and ventured into what is now Grand County, where a pass east of Berthoud Pass is named for him.

His partner, Andrew Sublette, also came across the Divide to trade in Grand County, as well as Ceran St. Vrain, whose fort was near modern Platteville. 26 year old Tom Smith was with a group of trappers who entered the northern part of Grand County in 1827, where they were attacked by either Ute or Arapahoe Indians. Tom was hit in the leg by an arrow, splitting the bone and creating a life threatening infection. Amputation was needed but none of the party had the nerve to perform the operation. So Tom took a butcher knife and amputated his own leg. As “Pegleg Smith” Tom later became noted as one of the greatest horse thieves in the West, but was never prosecuted.

The beaver trade was essentially over by the 1840s as silk replaced beaver pelt as the stylish material for top hats. In 1842, famed traveler Rufus Sage came over Muddy Pass into Middle Park, but recorded almost no hunting activity there. On the other hand …fishing was great! His party caught over 50 pounds of trout in one morning. Noted mountain man Jim Bridger and another guide, Joseph Chatillon, let the infamous Sir George Gore on an extravagant hunting expedition in Middle Park. Despite the senseless slaughter of thousands of game animals, Gore has been immortalized with a mountain range, canyon and pass named for him.

One of the earliest of the mountain men to discover what was to become Grand County arrived in the Fraser Valley as early as 1860, soon after gold was discovered in Colorado. Charley Utter, known as “Colorado Charley”, was considered the prototype of rough trappers and traders. He was unique, though, in that he insisted on taking a bath every day, whether in the hot springs or beneath frigid waterfalls. In 1864, Charley was one of the first to make use of Berthoud Pass driving cattle that he raised at Troublesome Creek. His home was host to various adventurers who came to explore the prospects of Middle Park. He would eventually work with the famous Buffalo Bill Cody, appearing in “Wild West” shows.

When Kentuckian Beverly D. William spent some time in Grand County, he realized the Grand River was originally named the Colorado. As a Washington delegate from the newly organized “Jefferson Territory” (as this area was known at the time), he was instrumental in getting the named changed to the “Colorado Territory”, although the river was called Grand River until 1921.

The idea of diverting water from the Colorado River on the Western Slope of the Continental Divide to the productive farmlands of the eastern plains had been a dream of planners as early as 1929.  Subsequently,  a long period of drought and the sagging economy of the “Great Depression” whetted demands for what became the largest trans-mountain diversion project ever built.

The Colorado-Big Thompson Project takes water from Grand Lake on the western side of the Continental Divide to the Big Thompson River on the east.  The water flows through a 13 mile tunnel beneath Rocky Mountain National Park.  In order to supply the residential and farming needs of Northeastern Colorado, the project was begun in 1938 and continued through the years of World War II.  The first water flowed though the tunnel, named for Senator Alva B. Adams, on June 23, 1947.

In order to assure an adequate supply from Grand Lake, a dam was built creating Shadow Mountain Reservoir.  A larger lake, Granby Reservoir was then built below, with a unique pumping plant that forces water into Shadow Mountain.  The Farr Pumping Plant cost over $9 million and provides an additional 700,000 of irrigated land to northeastern Colorado.  Further reservoirs were added, both to supplement the diversion and to compensate the water needs of Western Colorado.  These include Willow Creek and Windy Gap Reservoirs in Grand County.

While most legislators were enthusiastic about the project, U.S. Representative Edward Taylor was vehemently opposed to the reduction of water flowing down the Colorado River.  A compromise was reached in the creation of Green Mountain Reservoir (on the Blue River), which reserves water to replenish the Colorado River.   The city of Denver later claimed upstream water on the Blue River for the massive diversion project of Dillon Reservoir

Claims on the water of the Colorado River range from the fruit and wine regions of the Grand Valley in Colorado all the way to Los Angeles and Mexico.  It can be said that every snowflake which falls in Western Colorado had already been over-appropriated, especially during drought periods in the arid West.
