Crook, Kelly E.; Scatena, Fred N.; Pringle, Catherine M. 2007. Water withdrawn from the Luquillo Experimental Forest, 2004. Gen. Tech. Rep. IITF-GTR-34. San Juan, PR: U.S. Department of Agriculture, Forest Service, International Institute of Tropical Forestry. 26 p. This study quantifies the amount of water withdrawn from the Luqillo Experimental Forest (LEF) in 2004. Spatially averaged mean monthly water budgets were generated for watersheds draining the LEF by combining long-term data from various government agencies with estimated extraction data. Results suggest that, on a typical day, 70 percent of water generated within the forest is diverted before reaching the ocean. This is up from an estimated 54 percent in 1994. Analysis showed that up to 63 percent of average monthly stream runoff is diverted from individual watersheds during drier months. Watersheds with large water intakes have the most dramatic decrease in streamflow, particularly the Rio Espiritu Santo watershed, where 82 percent of median flow is diverted.
