On May 8th, KlamBlog editor and chief writer Felice Pace was interviewed on Jefferson Public Radio's Jefferson Exchange. The discussion included the US Bureau of Reclamation's decision to use taxpayer funds to pay for private irrigators to pump 45,000 acre feet of groundwater for irrigation this growing season. Felice questioned whether taxpayers should be footing the bill so that irrigators within the sprawling Klamath Irrigation Project can mine groundwater in order to fully irrigate during a drought.

Ever since Reclamation was forced to release water to the Klamath River to prevent "jeopardy" to ESA-listed Coho Salmon, the Klamath River Basin's Irrigation Elite has been able to continue fully irrigating even in drought years by mining the Upper Basin's deep aquifer, extracting groundwater in an unsustainable manner.
Groundwater mining occurs when the amount of groundwater extracted over time exceeds the amount of groundwater recharge. As shown in the graph below, the deep water table in the Tulelake Area (the lower Lost River Basin) has dropped significantly since 1992 when Reclamation was forced to allow more water to flow down the Klamath River. The groundwater aquifer has failed to recover even during years of above average precipitation and snow pack.
The irresponsible lowering of the groundwater table in order to fully irrigate during drought years has caused nearby towns (Tulelake in California, Merrill and Malin in Oregon) to drill deeper for drinking water. Even so, Oregon Department of Environmental Quality (DEQ) testing indicates that drinking water wells in the Oregon portion of the Lower Lost River Basin are polluted with nitrates, pesticides and other toxic agricultural residues.
Oregon DEQ has been reported as calculating that 15,000 acre feet of water could be safely extracted from groundwater in the Tule Lake Area (lower Lost River Basin) this year. Reclamation is using taxpayer funds to facilitate the removal of 3 times that amount!
Another silent Klamath Salmon disaster
Meanwhile fish disease levels in the Klamath River below Iron Gate Dam continue to rise. During what should be the height of salmon out migration, few juvenile salmon are showing up in mid-Klamath River monitoring traps operated by the Karuk Tribe.
