PRF insurance in Lassen County, California: 2027 grids, values and record

Pasture, Rangeland, Forage (PRF) is USDA’s rainfall-index insurance for grazing land and hay ground. USDA’s 2027 files offer it in Lassen County on 37 grids: 23440, 23740, 23741, 24036, 24037, 24038, 24039, 24040, 24041, 24335, 24336, 24337, 24338, 24339, 24340, 24341, 24635, 24636, 24637, 24638, 24639, 24640, 24641, 24935, 24936, 24937, 24938, 24939, 24940, 24941, 25235, 25236, 25237, 25238, 25239, 25240, 25241. It pays when precipitation in the grid over two months you choose comes in under a set share of normal.

USDA’s 2027 county base values, the same on every grid in the county. Protection per acre is the value times your coverage level times a productivity factor of 60 to 150: grazing at 90% and 100 is $12.60 an acre.

Example, not a recommendation: 100 acres of grazing at 90% coverage, productivity factor 100, half in April to May and half in June to July, on grid 23741, the middle of the county’s 37 grids by premium. The full premium is $329: USDA pays $168 and you pay $161, or $1.61 an acre. Run over 1951 to 2025 at 2027 rates, it would have paid in 53 of 75 years, an average of $288 a year, or $2.88 an acre. That is the past record, not a forecast, and it leaves out the administrative fee.

What each pair of months costs in Lassen County

At 90% coverage, across the 37 grids that touch the county: the middle grid first, then the lowest and highest. The premium is the full rate per $100 of protection; USDA pays 59% at 70%, 59% at 75%, 55% at 80%, 55% at 85%, 51% at 90%. Normal is the grid’s average precipitation for those months. A year counts, of the 75 from 1951 to 2025, when the grid’s index for those months came in under 90% of normal, which is when a 90% policy pays.

The wettest pair of months here is November to December (5.31 in on the middle grid) and the driest is July to August (0.63 in). Coverage costs least in February to March and most in July to August. The months to insure are the ones when a dry spell costs you grass or hay, not the cheapest ones.

The last five years in Lassen County, and 2026 so far

The index for each pair of months as a percent of normal (100 is a normal year), on the middle grid (each grid has its own; the calculator shows yours). Shaded cells came in under 90%, where a 90% policy on those months would have paid. 2026 shows the 6 pairs of months USDA has published so far.

PRF dates for 2027

  • Dec 1, 2026: acreage report.
  • Sep 1, 2027: premium billed, no earlier than this.

From 2027, grazing acres need livestock you have an interest in, equal to at least 25% of the stocking rate, or no payment is due and the premium is still owed. PRF pays on the grid’s precipitation index, not on your production. How PRF works · Before you sign · PRF in California

A grid is a quarter degree of latitude by a quarter degree of longitude, about 17 miles north to south. Your grid follows from a point inside the acres you insure; type a ZIP or coordinates in the calculator to find it.

How much does PRF cost per acre in Lassen County?

It depends on the grid, the months, the coverage level and your productivity factor. USDA’s 2027 county base value is $14.00 an acre for grazing. At 90% coverage and a productivity factor of 100, grazing land is protected for $12.60 an acre, and the full premium runs $19.20 to $37.74 per $100 of protection depending on the months, on the middle grid. USDA pays 51% to 59% of the premium. In the example above, 100 acres of grazing at 90% with half in April to May and half in June to July, you pay $1.61 an acre on grid 23741. The calculator gives the figure for your acres and months.

How often has PRF paid in Lassen County?

At 90% coverage a pair of months pays when the index comes in under 90% of normal. Over 1951 to 2025, on the middle grid, that happened in 35 to 42 of 75 years, depending on the months. Run at 2027 rates, $1 of full premium at 90% would have paid back a middle $0.88 across the county’s grids and months. That is the past record, not a forecast.
