Holtzman for governor?

According to the Denver Post, Marc Holtzman has decided to attend the state convention.

The Denver Post has more on the Marc Holtzman controversy. They write, "Credibility problems dogged Republican Marc Holtzman's gubernatorial campaign last week as a series of contradictions and straight-out lies were disclosed in a Denver courtroom. Questions also were raised about Holtzman's knowledge of donors - including his father's company - who gave money to a Virginia-based nonprofit group that contributed to a Colorado anti-Referendum C committee...

"Holtzman's campaign manager, Dick Leggitt, admitted Friday that he lied to a Denver Post reporter in an e-mail by fabricating poll numbers that purportedly showed Holtzman's name recognition going from '10 percent to 70 percent and his favorables among GOP primary voters are now just slightly less than (U.S. Rep. Bob) Beauprez's (39 to 42)...'

"The case centers on how much coordination and control are legally permitted between political-issue committees and candidate campaigns. The complainant, lobbyist Steve Durham, alleges Holtzman was inextricably linked to the 'If C Wins, You Lose' committee."

CloudSat and CALIPSO

Here's a roundup of yesterday's launch of CloudSat and CALIPSO from Nature. They write, "The satellites will fly in formation, taking measurements of the same part of the sky within 15 seconds of each other. Their goal is to enable scientists to understand exactly how clouds absorb and reflect the Sun's radiation. This effect helps to regulate the Earth's climate in a way that depends on the clouds' altitude, density and colour.

"The inner workings of clouds are currently something of a mystery, which introduces uncertainties into climate models that predict the progress of global warming. 'Clouds are a critical but poorly understood element of our climate,' says Graeme Stephens of Colorado State University, Fort Collins, who leads the CloudSat science team.

"Both satellites are equipped to slice through the clouds to find out how water droplets and aerosol particles are distributed inside. CloudSat's radar will be able to pick out large water droplets in thick clouds, whereas CALIPSO (the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite) will use the visible-light equivalent of radar to pick up finer detail in wispy clouds. Previous satellite observations have measured little more than cloud thickness."

Fountain Creek management

The Pueblo Chieftain reports on a recent study of the state of Fountain Creek. From the article, "Sections of Fountain Creek tributaries are becoming straighter and shorter in developed areas to the north, while the creek is meandering more and lengthening as it moves through Pueblo. A 'geomorphology' study incorporating aerial photos, scientific measurements and on-the-ground observations was presented Friday to the technical advisory committee of the Fountain Creek Watershed Plan by Graham Thompson of URS engineering. Simplified, geomorphology means the shape of the earth surrounding Fountain Creek, Thompson said. The study complements the hydrology and hydraulics studies which earlier looked at water patterns and structures in the Fountain. The latest study helps explain how sediment is moved along the creek. The study found flood events experienced every 18 months or so, not just the 100-year floods, have an impact on the creek. That impact is referred to in engineering jargon as a channel-forming discharge...

"Using aerial photos, Thompson showed how Fountain Creek has meandered in different areas for the past 50 years. His presentation concentrated on areas where the change has been greatest - movement of the creeks by 10 percent or more - because all portions of the creeks change course over time. Development in Sand Creek, Cottonwood Creek and Monument Creek has created steeper, narrow channels that risk bank erosion, he said."

The dilemma of efficient irrigation
A picture named denver2008new.jpg

Farmers on the lower Arkansas river are being discouraged from installing more efficient watering systems due to the effects on return flow to the main river, according to the Lamar Daily News. From the article, "State engineer Hal Simpson confirmed that Witte [Steve, Water Division 2 engineer] had been sent to talk with the farmers to try to explain the seriousness of the situation. According to Simpson, it is not a matter of telling farmers they can no longer have the same allotment of water, but rather how they use that water. Simpson agreed that sprinkler systems make more efficient use of the water. The problem is that because a wider area can be irrigated with the same amount of water, there is less to seep down into the ground and eventually return to the river.

"Flood irrigation, on the other hand, uses more water per acre and is much more labor intensive, which increases the farmer's cost per acre. The obvious choice for the farmer is to use sprinklers and get more coverage with less man hours. Flooded fields, however, allow the water to seep deeper into the ground and return more water to the river. The issue is that less water returned to the river leaves the region's farmers open to another challenge from the state of Kansas about insufficient return flow to the Arkansas, according to Simpson.

"Simpson said that in the lawsuit brought and won by Kansas water users, it was the government that paid the $35 million settlement. 'I doubt that the government will step up and pay another settlement on behalf of Colorado water users again,' he said.

"Local farmer Bud Scranton counters that there is more to the story than how much acreage is irrigated with the allotted water. He believes that officials are not considering the drought's effects on the land.

"According to Scranton, the water must pass through about 12 feet of ground before it gets to the clay barrier which carries the water back to the river. The drier the ground, the less likely that any of the irrigation water will reach the barrier because it is quickly absorbed and used by the plants within the top few inches of the soil.

"In wetter years, the irrigation water can contribute to the return flow because it is not so quickly absorbed at the surface. The bottom line said Scranton, is that 'Mother Nature is going to be the one to solve this problem. As soon as we get some nomal moisture, we will be in good shape with return flow.'

"So, it is, in fact true, that farmers who irrigate more efficiently on the same amont of acreage, will be penalized for it. Adding to the confusion is the fact that the Natural Resource Conservation Service (NRCS) is currently providing cost sharing, which defrays 50% of the cost for installing the sprinkler systems.

"Simpson said that part of the problem is the unique situation in the region, which is unlike other farming areas in the country, where more efficient watering systems are a win-win situation. The water short condition of the region, the fact that all rivers flow out of the state and that water compacts have been made with all downstream states agreeing to share the river water, makes the issue of more efficient watering a thorny one."
