Subject: Mono Basin Clearinghouse Updates for 11/4/01


Dear Friends,

We have lots of new and updated items on the Mono Basin Clearinghouse this month!


RAW DATA

Real time data explanations updated
There is a frames page that shows LADWP's real time data page along with explanations (from MLC) of what the data actually means. These explanations had been last updated in April, and now they are updated for the October-March period. The minimum flows for each creek are bolded so you can quickly gauge how the actual flow compares to the Water Board-ordered minimums. See http://www.monobasinresearch.org/data/mbrtdframes.htm

Mono Basin Riparian Plantings and Survival, 1993-2000. A table showing the numbers of trees planted in revegetation efforts since 1993. Shows species planted at each location for each year, and at least one subsequent survival count for each. At the bottom there is a summary table showing totals for everything and broken down by stream. In the future we hope to add maps showing locations of plantings.
Planted Surviving (at last count)
Cottonwood 1189 827 (70%)
Willow 1273 711 (56%)
Jeffrey Pine 1687 682 (40%)
Lodgepole Pine 187 76 (41%)
total 4336 2296 (53%)
See http://www.monobasinresearch.org/data/riparian.htm

Piezometer data, Rush and Lee Vining Creek, 1995-2001. This year all of the piezometers on Lee Vining Creek went dry by October 18. Around July 15th flows dropped below 40 cfs and after August 1, groundwater levels plummeted to levels not yet seen in A2, B1, C1, C2, and C3. This is the first time A1, A2, B1, C1, C2, C3 have ever been dry since they were installed, and the first time B3 has been dry since the 1997 flood. For Rush Creek, except for Piezometer 2, October 2001 had the lowest groundwater levels since Channel 10 was rewatered in October 1995. See http://www.monobasinresearch.org/data/index.html#HYDROLOGY

August 25, 2001 Shorebird Count. Lots of American Avocets on the north shore. We have data online for our shorebird counts as far back as 1997. See http://www.monobasinresearch.org/data/index.html#BIRDS

Weather Summary for October 2001. October 2001, based on the records of our internet weather station that go back to 1996, had the warmest low and warmest average temperature for any October since at least 1995. September 2001 was the warmest September as well. See http://www.monobasinresearch.org/data/weather.htm


LINKS/GIS DATA

We've added a couple of aerial photography resources to the GIS page. The Fairchild Aerial Photography Collection at Whittier College is a great resource for aerial photos taken all over the state of California between 1900-1950s. Mono Basin aerials include 1929, 1930, and a 1953 or 54 mosaic. Thanks to John Bair who gave me quite a bit of info about this resource. Also listed on the GIS page are the 1999-2001 aerials that DWP has had flown and are available through IK Curtis using Photomapper software. See http://www.monobasinresearch.org/gis/index.html


ONLINE REPORTS

Gravity Modeling of Black Point, a “Surtseyan” style Tuff Cone, near Mono Lake, California, a Senior Thesis by Jim Schneider, UC Davis. Does not contain figures. This is the first undergraduate research we have posted on the Clearinghouse. See http://www.monobasinresearch.org/onlinereports/index.html
