Water quality monitoring network in Strymonas Basin The main objective of water quality monitoring network is to provide for adequate information for the assessment of the pressure that imported pollution and intensive agriculture put on its surface water. The network includes 16 sampling stations where eleven parameters are monitored every 15 days. Temperature (T), pH, dissolved oxygen (DO), electrical conductivity (ECw) and REDOX are measured using a portable multi-parameter + 3- 2+ 2+ + + device while NO3, NH4 , PO4 , Ca , Mg , K , Na are measured through the analysis of water samples in the laboratory. Also BOD5 is measured at certain sample stations (No 1, 3, 13 and 16) For the spatial distribution of the 16 stations the functioning and the management of surface water network in the catchment was taken into account. Hence the stations were established at the inlets and outlets of either the natural water bodies (e.g. Strymon River, Lake Kerkini, Ag. Ioannis River etc) or the main irrigation and drainage networks in the catchment. Also care was taken in order the position of the stations to be identical to that ones where water level auto-recorders have been established (see next paragraph) The 1st sampling station (No 1) has been established in Strymonas River, just upstream the flow control structure “Ypsilon 1 (Y1)” (map1.1), aiming at the monitoring of water that comes from Bulgaria. The distance from the borders is about 10 Km, and there is no any human activity in the area that could effect the quality and quantity of the water that inflows from the neighbor country. Also, since this position is too close (less than 500m) to the flow control structure “Ypsilon 1 (Y1)” (see maps 1.1 and 1.2) it can give the quality of the water that diverts into the irrigation networks Iraklia and Sidirokastro (see map 2). A sampling station (No 9) has been established downstream of Agios Ioannis’ springs (map 1.1), aiming at monitoring the quality of water that inflows into the irrigation network of Ag. Ioannis (map 1.2). The sampling station No 13, has been established at Aggitis River, aiming at monitoring of the quality of water that comes from its catchment. Also this station gives information with regard the quality of the water that fed a part of Dimitra’s irrigation network (map 1.2). 1 A number of sampling stations were established inside Lake Kerkini due to its importance for both its ecosystem and its role as a provider of water for irrigation. Hence the sampling station No 2 has been established at its upper end, sampling station No 3 in the middle of the lake and sampling stations No 4 and No 5 close to the flow control structures “Ypsilon 2 (Y2)” and “Ypsilon 3 (Y3)”. The later fed with water Strymonas River downstream the dam of the lake and the irrigation networks of Provatas (No 4), Nigritas and Dimitritsi networks (No 5) (see map 1.2). A water body of major importance in the catchment is the drainage ditch of Belitsa (map 1.1 and 1.2). It receives almost all of the drain water that comes from the agricultural area at the west side of Strymonas River, and following fed with water the irrigation networks of the Land Reclamation Agency and Neos Skopos (map 1.2). Four sampling stations have been established in Belitsa ditch No 6, No 7, No 8 and No 10 (map 1.1 and 1.2). The sampling station No 6, is aiming at monitoring the quality of water that drains from the upper part of Sidirokastro network and a very small part of Iraklias irrigation network (see map 1.3). Also station No 6 gives information for the quality of water at the upper end of Belitsa ditch. The sampling station No 7, is aiming at monitoring the quality of water that drains from the agricultural area of Iraklias irrigation network (see map 1.2 and 1.3) and outflows into Belitsa ditch. The sampling station No 8, has been established in the Belitsa ditch just downstream the outlet of the drain water that comes from the upper part of Provatas irrigation network. It is important to be mentioned here that the drain water of this area gives the main discharge of Belitsa ditch, due to the high quantities of irrigation water for the rise crops. The sampling station No 10, has been established in Belitsa ditch just before Ag. Ioannis and Belitsa brunch connection. Sampling station No 11 has been established in Ag. Ioannis springs and aims at monitoring the quality of water before the brunch connection of Ag. Ioannis and Belitsa. Sampling station No 12 is located in Strymonas River before its junction with the Belitsa ditch. It aims at monitoring the water quality of Strymonas River after it has been influenced by the drainage water of Dimitritsi, north part of Nigritas and the south part of Provatas irrigation networks (see map 1.2 and 1.3). 2 Sampling station No 15 is located in Strymonas River, just before Agitis River outflows in it. It aims at monitoring the water quality of Strymonas River after it has been influenced by the drainage water (see map 1.2 and 1.3) of the following areas: ° The south part of Nigritas irrigation network ° The west part of Dimitras network and ° The right and left Strymonas’ banks irrigation networks commanded by the General Land Reclamation Agency. The sampling station No 14 is located in Agitis River just before it outflows into Strymonas River and after it has been influenced by the drainage water of the east part of Dimitras irrigation network. Finally a sampling station, No 16, has been established at the outlet of Strymonas River (2 km before Strymonikos Gulf). It is near by the position where the innovated construction of discharge recorder is going to be established. 3 Map 1.1 .Water quality sampling stations in Strymonas Basin. 4 Map 1.2.

Surface water level monitoring network The surface water level monitoring network includes 12 water level auto-recorders and its main objective is to provide for an adequate number of water depth time series for the calibration and validation of the hydraulic model of the catchment. Additionally, the monitoring network will include discharge measurements at the same positions where the water level auto-recorders have been established in order water level – discharge diagrams to be produced. The type of the devise that has been selected constitutes an advanced data logging probe. It is completely self-contained and features an internal data logger with a pressure/level and a temperature sensor.
