Go With the Flow

"Have you ever dropped a stick in a river and wondered where it might go if it floated all the way downstream? Now you can trace its journey using Streamer." In addition to displaying the distance traveled, difference in elevation, and number of states, counties and cities the stick will pass through before reaching its outlet point, Streamer can do an upstream trace to show you which rivers and smaller streams fed into the spot where the stick was dropped.

Uffda

Much to the frustration of the local population the Devils Lake Basin is currently endorheic, but this may be about to change(photo is from a year ago). An epically inadequate outlet was finished in 2005. Like most land management issues this one is complex(see bottom of pg. 45), but one thing is for sure: at several points in the past Devils Lake naturally flowed into the Sheyenne River and eventually into Hudson Bay. The state government wants to armor the outlet to prevent the natural overflow, but the city of Devils Lake owns the land and is preventing any construction until a negotiated lake level is agreed upon.

You're soaking in it

"There it is. Take it."

Eighty years ago, William Mulholland completed his final project: the St. Francis Dam, which converted San Francisquito Canyon--about 5 miles northeast of what is now Santa Clarita, California--into a 38,000 acre-foot reservoir for Los Angeles/Owens River aqueduct water. You're probably familiar with Mulholland's name --he designed and built the Los Angeles Aqueduct and the beginning of the system with which Los Angeles is supplied water from the Central Valley--and as a gesture of gratitude, the city named its most scenic highway in his honor. Mulholland, the California Water Wars, the aqueduct, and the dam were also referenced and alluded to extensively in Roman Polanski's Chinatown. But the man who helped build an immense metropolis by bringing water to the desert has only a small fountain as a memorial to his legacy. Three minutes before midnight, on March 12, 1928...

This LA Times article will get you clued in to some recent developments. But what is the most responsible course of action to deal with the Salton Sea? It's part of a complex hydrologic system and has a pretty unusual history. To me, this seems one of the best reminders that ecological issues are among the trickiest we face.

Next Thursday, NASA will announce the discovery of huge water ice oceans on Mars. Lying less than a metre beneath the surface south of 60° latitude, the water ice reservoirs if melted would form an ocean 500m deep covering the entire planet. NASA insiders believe these findings could result in a manned landing within 20 years.
