Steps to generating a sample plan. There are six short steps involved in generating and saving a sampling plan.
Step 1: From the pull-down menu, select the project you want to survey. This will populate the work area in step 3 with a list of Corps-managed recreation areas and associated default visitation statistics.
Step 2: From the pull-down menu, select the 2-month period you want to survey. This would ideally correspond to the two consecutive months receiving the highest monthly visitation.
Step 3: Identify recreation areas you want to include in the survey by following the instructions provided in the Survey Schedule Generator. Then add or change the visitation use and distribution statistics, as necessary, to accurately characterize visitation patterns on each recreation area.
Step 4: Click on "Generate Calendar." This will generate a sampling schedule (see example below) with 20 sampling periods distributed over the areas and dates specified in steps 2 and 3.
The probability-based sample selections are drawn "with replacement." This means that more than one recreation area can be selected for sampling on a single date as occurred on 7/11/2004 in this example. It also means that one recreation area can be selected more than once on a single day as occurred with "Rec Area A" on 7/3/2004. Sampling instructions for these situations are provided in the section "Guidelines for Survey Personnel," subsection "How Many Samples."

Step 5: Print the calendar. You will need to verify the locations and dates of sampling and to tally the number of refusals and completed comment cards each sample period.
Step 6: Rename and save the Excel file to a location where you can find it later. You may need to print additional copies of the calendar at a later date for use during data collection and data entry.
