Click here for all the inside skinny. Here’s an excerpt:

Please join Save The Poudre at the first bike “TOUR de POUDRE!” Come dressed as your favorite river species, or just come dressed! We’ll ride along the Poudre River bike trail from Watson Lake in Bellvue downstream to the Environmental Learning Center, and then rendezvous at Avogadro’s for libations and cheer.

Data Visualization with R: global climate change

From the R Bloggers website (David Smith):

Due to anthropogenic climate change, the average global temperature has increased steadily over the past decade or so. While we’re all familiar with the hockey-stick line chart of rising temperature, the change is even more dramatic on this animated globe showing the local effects of climate change.

The first half of the animation shows the monthly local change compared to historic averages (blue is cooler; red is warmer). The second half of the animation repeats the cycle, but introduces a moving 10-year smoother to reduce the variability in the temperature changes, making the global temperature increase much more apparent in the forecast part of the animation. The overlaid time series shows the global average temperatue deviations from the historical average, in degrees Celcius.

This animation was created by Matt Leonawicz, Lead Statistical Analyst at the Scenarios Network for Alaska and Arctic Planning, using the R language. He created a custom R package called “mapmate” (available on Github).

Dixon Reservoir drawn down for repairs

From the Fort Collins Coloradoan (Cassa Niedringhaus):

The 950-foot earthen dam on the north edge of the reservoir is classified as a “significant hazard dam” because of its proximity to homes to the east. The dam is located west of the intersection of Overland Trail and Drake Road in west Fort Collins. It’s prone to “seepage” in which water moves through the dam and erodes it away.

The reservoir’s water level has dropped significantly in recent weeks to allow the dam to dry out so work can begin to repair it. The dam is located in the city-managed Pineridge Natural Area.

The Dixon Canyon Ditch and Reservoir Company, which manages the operation of the reservoir, hired John Gauthiere of Gauthiere Engineering to head the repair project.

“It’s not a major risk, and we were not told we had to do it,” Dixon Reservoir Company president Doug Kokes said. “It’s going to have to be done sometime, so we said, ‘Let’s get it done now before it becomes a hazard.’ ”

Gauthiere submitted preliminary plans to the state March 30. Kokes said Gauthiere will submit finalized plans to the state this week.

He said he plans to spend the next eight weeks finding a contractor to do the construction work, which he said should take between one to two months to complete.
