A Sanford couple is taking on the federal government in general and FERC (Federal Electricity Regulatory Commission) in particular after they lost their lakefront home in May when the Sanford Dam was overwhelmed, causing major flooding. This is interesting since at the root of the dam disaster is the failure of FERC. For years, FERC kept humouring the dam owner, and tolerated its violations. Why it did that, when it could have taken much stronger action almost two decades back is a mystery. Hopefully, this case will help get it resolved.

On Tuesday, May 19, 2020 evening following two days of heavy (4-7 inches) rains, Edinville Dam breached at 1740 and downstream Sanford dam overflowed at 1900 hours, leading to highest ever water level in downstream towns, leading to evacuation of over 10 000 people, besides massive damage, including to roads, bridges, buildings and crops. Both were earthen dams, Edinville dam famously did not have sufficient spillway capacity to pass even half the PMF (Probable Maximum Flood) it was expected to get. USA has much better dam safety situations legally, institutionally and practically that we in India have, and yet this happened where problems were known. As India awaits in the South West Monsoon 2020, there is lot we need to learn here and worry about our dams. Continue reading “Michigan Dam failures: New Warnings for India’s Dam Safety”
Water use across US has been decreasing since 2005, has now reached pre 1970 levels, says the U.S. Geological Survey (USGS) study[i] published on June 19, 2018. According to a new USGS report[ii], 445 BCM (Billion Cubic Meters, all BCM figures are annual figures) of water were withdrawn for use in the United States during 2015. This represents a 9 percent reduction of water use from 2010 when about 489 BCM were withdrawn and the lowest level since before 1970 (511 BCM).

How is development possible along with environment protection? There are two kinds of answers possible to this question. The standard kind of reply would try to provide a list of options that are available to a given development need.

I was standing in a waste dump, with pigs, garbage and dumped clothes all around me when Mr. Shailendra Patel told me to take off my shoes.
Just a few steps ahead of me was a miracle.
In the midst of the dump, Mr. Patel went down to a sparkling spring of clear water and kneeled down. This was a living stream in the heart of Pune city, with “development” all around, with a sewage carrying nallah flowing right next to it. Crystal clear water gushed out of rock crevices, there was a small sandy pool with tiny fish, water skaters and a desolate looking statue of a jaldevata on a stone ledge.
Mr. Patel talked with ladies with their washing loads who came to the spring, with school children running past, late for the school, with construction workers brushing their teeth nonchalantly next to the spring. The problem was he could not talk with the people who stayed in huge apartment complexes right next to the spring. They find the place too filthy, despite the fact that the tankers that supply water to complexes fill up from springs like these.
One more problem was that the Pune city does not recognise existence of such springs and the City Development Plan has not marked this as a spring or stream. It is up for grabs. A building complex will be built over this at any time.
This led me thinking, how does a city recognise & protect living streams and springs? How can we make the city development plan leave them out of development activities? Are there examples where this happened somewhere? Continue reading ““Streams don’t like to be in Channels” Interview: Stream Restoration, Austin Watershed Protection Department”
USA’s tallest, Oroville Dam on Feather river in California suffered severe spillway damage, as discovered on Feb 7, 2017. As we wrote in our blog “Oroville Dam Spillway Damage in USA: Worst is yet to come”[i] on Feb 12, 2017, worse was yet to come, but the author did not imagine the threat would materialize so soon. Here we try to capture the key events since that blog. Continue reading “Oroville Dam damage in US: Many questions”
Oroville Dam, the tallest Dam in USA was found to have suffered severe damage to its spillway on Feb 7, 2017. A crater of about 180 feet width, 250 feet length and 30 feet depth was found in lower portion of the 3000 ft long spillway on Tuesday when 55000 cusecs (cubic feet of water) was flowing down the spillway.
That water release down the damaged spillway was stopped the same day. But the water level in the Oroville dam was than already over 80%, fast climbing to over 90% by the evening of Feb 9, 2017 and with inflow of 128000 cusecs on Feb 7, rising to 191000 cusecs on Feb 9, the officials of Department of Water Resources (DWR) of California decided to first test the damaged spillway by releasing 20000 cusecs twice on Feb 8, 2017. This further damaged the spillway, increasing the depth of the crater to upto 300 ft as per some reports and not only increasing the length and width, but also eroding the adjoining hills.
