1. (a) The map titled "annual potential net evaporation in inches for Equus Beds groundwater management district no. 2 (annual average evaporation minus annual normal precipitation)," prepared by the district and dated June 11, 2002, is hereby adopted by reference for the purpose of determining potential net evaporation from a free-water surface within the district.

2. (b) The values on the map shall be used in all situations in which the determination of potential net evaporation from a free-water surface is necessary, including the following:

   1. (1) Computing the annual amount of evaporation that will be caused by exposing the groundwater table;
   2. (2) calculating the quantity of surface water that is reasonably expected to be replaced with groundwater pumped under an approval of application or water right;
   3. (3) calculating the average annual evaporation from groundwater that will be used to determine annual water use; and
   4. (4) determining the maximum annual quantity of water that is perfected pursuant to K.S.A. 82a-714, and amendments thereto.
3. (c) The values shown on the map shall be used unless the applicant provides, or the chief engineer or the district has available, better or more site-specific data concerning potential net evaporation.

(Authorized by and implementing K.S.A. 82a-706a and K.S.A. 2003 Supp. 82a-1028; effective Dec. 10, 2004.)
