(~I i le- <br />..F~()r PC()/;/c <br /> <br />John Martin Reservoir - Fishery and Water Level Analysis <br /> <br />The following is an analysis for John (\~artin Reservoir of the relationship of reservoir water level to the quality of the <br />fishery and the correspondjng fishing recreation_ <br />This document contains: <br />· historicallllfornlation on angler use. <br />· angler expenditures and economic inlpact of the fishery at various water levels, <br />estinlated fish losses associated with declining lake levels, <br />· dollar value of estimated fish loss. <br />· and costs associated wIth rebuilding the fishery_ <br /> <br />ANGLER USE <br />The DOW conducted Intensive (full-time) creel census surveys in 1987l 1993, 19961 and 2001 (another creel is <br />scheduled for 2008). All of the surveys were conducted for a 6 month period (April-Sept), except for 1996 which was <br />done during the best three months of fishing (April- June). Fortunately, the creel surveys were conducted in years where <br />water levels of the reservoir \.vere quite varied and give us some predictive ability to tie fishing recreation with water levels. <br />The following chali cOlllpares the data: <br /> <br />Param'eter <br /> <br />1987 <br /> <br />1993 1996 (3 mo.) 2001 <br />1,500 10.000 71125 <br />4_7 3.0 7.0 <br />3,4 4.7 5_2 <br />9,430 29r052 451854 <br />21774 61181 8,818 <br />950/0 Res, 97, 1 ~/Q Res_ 96.70/0 Res. <br />50/0 NR 2_90/0 NR 3.30/0 NR <br />$46,903 $106,836 $1511781 <br />$19,599 $25,239 $41.031 <br />$66,502 $1321075 $192,812 <br /> <br />Avg.
