I gave a poster on "Tracking flood pulses and their impacts on water quality using a low-cost, open-source monitoring network in East Africa." Data from the network is available on Thingspeak. If you're interested in the base code that I use in the water level stations and the weather stations (take a measurement and then upload to Thingspeak via a GPRS connection), you can get it here - https://github.com/cldutton/MaMaSe.

The Mara is amazing low right now. We estimate the flows at around 1 m3/s at Purungat Bridge (see here for the water level data). The zebra and wildebeest had no trouble crossing the river.
Unfortunately, the low flows are probably contributing to the cholera outbreak in the upper catchment. Read more here - Bomet hotels closed over cholera outbreak and here - Two die of Cholera in Bomet.

2:50 pm - Alternator bearing froze in the middle of the Mara. We had already been suspicious of the new sound coming from our engine, and a friend's mechanic had checked it out, diagnosed the problem, and determined we could safely drive the 2 hours to the nearest town. We broke down a few hundred meters later.
2:53 pm - We had already ordered a new bearing from Nairobi as soon as we heard the diagnosis. Determined we couldn't get the part from Nairobi until the next day. Called our mechanic in Narok, 2 hours away, to source a more local alternative.
3:07 pm - Called our field assistant in Mulot, 1 hour away, to look for a back-up option.
3:11 pm - Called our friend whose family owns a shop in Aitong, 30 minutes away, to look for a back-up, back-up option. The closer the towns, the smaller they were, and the less likely we could find the part we needed, but it was worth the try.
3:49 pm - Determined a used alternator from Narok was the best/only option. Sent all the money we could (not enough) via cell phone to our mechanic to purchase the alternator.
4:05 pm - Our mechanic left Narok on a motorbike with the used alternator, heading for the Mara. The roboticists and I went to hang out with our friends we had been visiting. Chris, like a true sea captain, wouldn't leave the vessel, and insisted on sitting outside the gates in the afternoon sun with the Land Rover.
6:49 pm - Our mechanic arrived at our Land Rover in the Mara. She (the Land Rover) and Chris are outside the gate, and it's starting to get dark.
7:30 pm - Chris rolled into our friend's place, new (used) alternator in place and the Land Rover purring like her normal self again. Decided it was too late to drive, and a great opportunity to spend more time catching up with friends, so set up our tents for the night.
4 hours and 40 minutes from breakdown to repair in the middle of the Mara-- not bad! Of course, we have some great friends to thank for their help in getting things running again so quickly, and having a comfortable place to camp for the night. In Kenya, logistics are all about who you know, and how easily you can contact them. I can't imagine having worked here before cell phones!

Wouldn't be a true safari experience without a breakdown! Alternator bearing froze approximately 500 meters after a mechanic told us we could make the 2 hour drive to town. Fortunately we're near some friends who can help out, and we're pulling out all our logistics tricks to sort this out... wonder where we'll end up tonight...
