Task: Develop county-level coefficients of large farm unreported irrigation withdrawals. @laljeet @jdkleiner @rburghol

Action items:
- [x] Calculate volume of large farm unreported ( W_{unr_lg}) in all counties using rainfall deficit approach. Large farm unreported is the total irrigation volume, minus DEQ reported, minus small farm volume from before. W_{unr_lg} = W_total - W_{unr_sm} - W_{rep_irr} W_total = Total irrigated acres x Rainfall_Deficit
- [x] Create table with coefficients of large farm unreported as percentage of reported irrigation withdrawals in counties with usda and vdeq irrigation data for each county c and usda year y: C_irr_lg_c,y = W_{unr_lg} / W_{rep_irr}
- [x] Create table with coefficients of large farm unreported as percentage of reported withdrawals (all use types) in all counties with usda data for each county c and usda year y: C_tot_lg_c,y = W_{unr_lg} / W_{rep_tot}
- [x] Map of C_irr_lg
- [x] Map of C_tot_lg
- [x] Trend analysis: As with small farm irrigation, identify any counties with monotonic trend in all four years

When to use/prefer methods:

small farms:
- if VWUDS data is complete (high % of eligible reporters reporting), and small farm area varies with large farm area, small farm irrigation coefficient is robust method.
- if not, need ag census area.
how would def vs coeff compare if we use median instead of mean?

Bar Chart of Total State Irrigation by Year:

Crop Deficit Method w/Max Acreage
Crop Deficit Method w/Median Acreage
DEQ Reported
Irrigation Survey reported

Median coefficient results in higher unreported withdrawals in some counties where median = mean This bumps up the state's yearly unreported withdrawals

Proposed Method for limits on counties with large unreported withdrawals

Get the max irrigation demand for each year
Unreported withdrawals based on the coefficient method can't exceed the max irrigation demand.

Thanks Lal! This is interesting to see, and I think would put us in a much more reasonable ballpark of water demand. For instance, assuming June-August is 14 weeks, with a water demand of 1" per week for the first and last four weeks, and 1.5" per week for the middle six weeks, that would be a total water demand of 17".

I'd be inclined to set crop water demand over that period to 20" as an initial test and see how our numbers compare. If we were using 30" before and an average effective rainfall of ~12", we're assuming ~18" of water put on. Now we'd be down to something like 8" of water put on, so I suspect our volume estimates would be around 8/18 = 44% of what they were.

@rburghol what do you think?

@julieshortridge I think that makes lot of sense, both the final totals, and your idea to do more need in the middle weeks. Thanks to both of you!
