Waters Protection Ordinance
(WPO)

¹ The can­tons shall sub­mit to the FOEN a plan for meas­ures to re­medi­ate hy­dro­power plants that cause hy­dropeak­ing in ac­cord­ance with the pro­ced­ure de­scribed in An­nex 4a num­ber 2.

² The per­sons re­spons­ible for hy­dro­power plants must grant ac­cess to the au­thor­ity re­spons­ible for the plan and provide the re­quired in­form­a­tion, in par­tic­u­lar on:

a.

the co­ordin­ates and the des­ig­na­tion the in­di­vidu­al parts of the plant;

b.

the flow rates of the wa­ter­course con­cerned with meas­ured val­ues at in­ter­vals of no more than 15 minutes (hy­dro­graph) over a peri­od cov­er­ing the past five years; If these meas­ured val­ues are not avail­able, the hy­dro­graph may be cal­cu­lated us­ing data re­lat­ing to hy­dro-elec­tric power pro­duc­tion at the plant and the wa­ter flow;

c.

the meas­ures car­ried out and planned to re­duce the ef­fects of hy­dropeak­ing;

d.

the avail­able res­ults of the study on the ef­fects of hy­dropeak­ing;

e.

the planned struc­tur­al and op­er­a­tion­al changes at the plant.
